Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for sharing and exchanging data files between enterprises, which enables efficient sharing and exchange of data files among a plurality of enterprises via the Internet.

[0002] The present invention also relates to a business cooperation system between companies that includes a data file sharing / exchange system between the companies and that can efficiently perform business processes performed between a plurality of companies via the Internet. Things.

Further, the present invention relates to a business cooperative system design method for designing a business cooperative system between specific companies using the business cooperative system.

[0004]

2. Description of the Related Art With the development of the Internet technology, information provision and information sharing between companies have been performed via the Internet instead of using tools such as telephones and facsimile machines. In addition, business processes such as a product ordering business performed through a plurality of companies are also being performed through the Internet.

[0005]

However, the use environment of the electronic space formed on the Internet is currently being developed and designed individually by the respective companies.
For example, even when companies of the same type of business provide similar information, the structure and presentation means of the information providing homepage are different for each company. For this reason, companies should open their homepages individually at a cost of several million yen to several tens of millions of yen, supposedly "to make efforts to differentiate between companies based on the content of information". The presentation method is being developed individually for each business requirement. "

[0006] To put it another way, in preparing a business document to be sent to a customer, instead of using standard A4 copy paper as a paper medium, a custom-made high-quality Japanese paper is produced and used each time. Is equivalent to the act of being. Further, as a similar phenomenon, there is an illusion that a homepage content as an advertising medium and “means for presenting / exchanging actual information”, which should be standardized, are completely integrated. As a result, we are now far from the vector of human standardization efforts that humanity has cultivated to date.

As a natural consequence of such a problem, for example, "If information to be sent by facsimile is to be sent using more sophisticated means such as a homepage on the Internet," the sending of the information is performed. The cost of acquiring and using the environment (web application development and operation costs and human costs such as operation training for users) is higher than the cost of transmitting information using a facsimile, and the situation of end-of-life falls frequently. It is doing.

Thus, at present, in projecting our business activities on electronic space, we are forced to construct "applications" each time with labor intensive means prior to the Industrial Revolution. I have. As a result, there are various "costs that would be unnecessary if standardized" when using the electronic space, which has caused a serious obstacle to the spread of the electronic space.

Considering the inherent potential of the Internet, the cost of developing and using an information exchange / sharing environment between companies should be "endlessly free" in view of the development vector of human history. It is a normal figure when it is. In fact, in the increasingly standardized world of e-mail exchange, communication costs are being reduced indefinitely.

An object of the present invention is to provide a method for exchanging and sharing information in an electronic space where the Internet / computer newly obtained by human beings is integrated, based on the above-mentioned historical view and recognition of the current state, and construction of the method. It promotes normal and reasonable evolution of the electronic space by "standardizing" the means, cutting the non-essential communication costs as a result, and returning the network usage environment to the original vector of human history development.

[0011]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a data file sharing / exchange system between companies of the present invention provides a common space for sharing / exchanging data files between companies on the Internet. Means for providing common space; database means capable of holding various kinds of information; access operations to data files posted on the common space by a plurality of companies based on access management information held in the database means Access control means for managing authority; file operation function providing means for providing each of the companies with an operation function including at least one of uploading, downloading, updating and deleting of the data file; Upload, download, update, or delete files If the Re of operation is performed, is characterized by having an electronic mail notification means notifies to companies said is previously designated from among the companies.

Here, it is generally desirable to have data encryption means for encrypting the data transfer via the Internet.

The access operation authority for the data file includes an upload authority, an update authority, a delete authority, and a download authority for the data file.

[0014] In this case, the database means includes a history holding means for holding at least one of a download history and an update history of the data file, and the access control means also manages an access right to the history holding means. It is desirable.

It is preferable that the access management information can be freely updated by a predetermined company among the companies, for example, a sponsoring company presenting a data file.

Next, the data file sharing / exchange system between enterprises according to the present invention is characterized in that in addition to the above-mentioned configuration, there is provided state transition management means for managing the state transition of the data file.

[0017] The state transition management means may be configured to, when the data file is operated by the company, shift the data file to a transition state corresponding to the operation.

[0018] For example, the state transition management means may correspond to the data file in response to the trigger by using a preset condition not related to the operation by the company and not related to the data content of the data file as a trigger. It can be configured to shift to a transition state.

Next, the present invention relates to a business cooperation system between enterprises provided with a data file sharing / exchange system between enterprises having the above-mentioned configuration. In this system, the state transition management means comprises: When the data content of the data file satisfies a specific condition as a trigger, the data file is shifted to a transition state corresponding to the trigger.

The file operation function providing means in the business cooperation system between companies of the present invention includes a data disclosure function of performing a disclosure operation of new shared information for posting the new data file on the shared space; At least one of a data update function for updating or determining the contents of the data file formed in the shared space, a data browsing function for browsing or downloading the data file, and a data deleting function for deleting the data file. It is characterized by providing two operation functions.

Next, the present invention relates to a method for designing an individual business cooperative system using the business cooperative system between enterprises having the above-mentioned configuration. In the method, the individual business cooperative system is provided on the common space. A data file related to the cooperative system is displayed, and at least the access control means, the file operation function providing means, and the means including the state transition management means are used, and on the common space, between the development contractor and the contractor. In addition, the design work of the individual business cooperation system is performed.

[0022]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a business cooperation system between companies according to the present invention will be described below with reference to the drawings.

1. Outline of configuration of this system In the business collaboration system between companies in this example, the business processing system between companies is decomposed into the following three layers based on the complexity of the components, and each usage environment is divided into an ASP provider ( App
ligation Service Provide
r). In other words, by decomposing the layers of means for realizing the information sharing and exchange business between companies from the following viewpoints, unified operability and screens for projects of various levels (business requirements, scale, schedule, budget, etc.) The configuration / production process can be applied, which can contribute to the improvement of applicability and convenience of a user company.

(1) Layer 1: Simple and single data file sharing / exchange processing system between companies In layer 1,
It supports a system for sharing and exchanging data files created using OA software such as Excel (registered trademark of Microsoft Corporation) in a one-to-one, one-to-many, or many-to-many relationship. In this system and its service environment, "Collaboration Workspace" is used for exchanging and sharing data files.
(CW)) ”.

Referring to FIG. 1, a user (company A, B, C, D./D.) Registered in advance into a common space CW provided by the business cooperation system 1 between companies in this example.
・ ・) Receives ID and password authentication, logs in, and performs file exchange and sharing work. The users of the common space CW are classified into organizer companies (for example, company A) and user companies (for example, companies B, C, and D).
The access right to the common space CW is controlled and managed by the access control function 2 of the system 1.

The sponsor company A has individual user companies B, C,
For each ID of D, the authority to upload, download, update, and delete files can be given. In addition, the organizer company A has a function that, for each file, a function that an automatic e-mail guide is notified to a specific company (in many cases, the organizer company A) when any user company downloads the file. And "When the organizer company A or the user companies B, C, and D upload / update the file, the automatic e-mail guidance is notified to the user companies B, C, and D having the authority to download the file. Function can be used or not. Further, the sponsor company A can browse the download history log of each file. Note that information flowing on the net in connection with all the above processing is subjected to encryption processing by the function of the present system 1.

Compared with the current information exchange means via an e-mail attached file, in the data file sharing / exchange processing system provided in the layer 1 by the system 1 of the present example, it is necessary to transmit data for each business participating company. To easily check whether sent data has been viewed / not yet viewed by using the automatic e-mail function or by referring to the history log. By setting the authority for uploading and updating data for each participating company, there is a requirement that data contents change after data is sent, or a requirement that information is transferred between multiple companies and business is advanced For example, an environment for implementing a complicated information exchange / sharing system between companies can be obtained inexpensively and quickly.

(2) Layer 2: Data file sharing / exchange processing system "taking into account the state transition" between companies In Layer 2, data files created using OA software such as Excel are shared / exchanged. ,
The system is the same as the layer 1 in the above (1). However, it is characterized in that it not only lends space for installing shared information, but also supports processing in which the meaning of the data file changes in accordance with the progress of business processing.

Referring to FIG. 2, in the business collaboration system 1 of this example, for example, a file 3 in which delivery date desired information presented on a common space CW for a plurality of companies from a specific company is entered. Is a state (state 1) whose transition state is “desired delivery date” at the initial presentation stage. At the stage when the consensus of the concerned parties is obtained, the transition state of this file 3 is not the “desired delivery date” but the “determined delivery date” state (state 2) with the same contents. .

In the system realized by the layer 2 of the business cooperation system 1 in this example, by adding the state transition element to the static file 3, the data file shared between the companies is Project social business processes. In other words, it plays a role of giving an “application software” element, which cannot be obtained by simple data file sharing / exchange operations, to data file sharing / exchange operations between companies. As a result, the user of the business collaboration system of the present example can obtain the application “without developing the application”. This has the effect of dramatically reducing the cost of obtaining the same benefits as current application development.

The point of the system realized by the layer 2 of the business cooperation system 1 of this example is that the common space CW itself does not perform an operation on the “contents of the data file” itself, but the “data file” is stored. That is, the state transition element is brought into the “environment”, and the state of the data file in the current state is expressed. In other words, the above-described concept is embodied in such a form that the common file CW having the state transition machine or the state transition management function 4 "wraps" the data file.

(3) Layer 3: Application system supporting business process between companies In layer 3, information sharing / exchange means is realized not through data files but through dedicated application software. When it is necessary to present and operate information that cannot be expressed in a simple file, or when a special graphical screen is required due to business policy, user's proficiency in computer operation, or other reasons, it is not a simple file but a dedicated file Creates and presents application software with screen and operability.

The main features of the method for developing application software created on layer 3 are the following three points.

Features from the individual requirement analysis stage to the implementation stage (Requirement analysis combining the standard form of business process
"Implementation method" Operations on the data, "public", "update"
It is limited to the four basic functions of "view" and "delete", and the actual operation screen also has these four functions as a menu, and the screen is used uniformly for all requirements. In other words, the approach for realizing each requirement on the net has been changed from the conventional order of “individual requirements → actualize individual requirements on the net” to the order of “the above four function menu → application of individual requirements”. It is a conversion. By limiting the functions that can be operated for each login ID to the business collaboration system 1 of this example, and by dynamically changing the availability of functions depending on the state of the common space CW, The individual business process is applied to the business cooperation system 1 of the present example by performing control such that another person can rewrite the data at some time just by looking at the data. That is, this is an act of mapping an individual business process to a model space of a three-dimensional combination of a finite number of states, four basic functions, and a user ID.

This makes it possible to simplify seemingly complex business processes with a unified framework.
Individual system requirements that existed as an infinite number of patterns can be reduced to simple combinations of functions and elements. As a result, standardization of the requirement analysis step and the procedure of transferring the analysis contents to the mounting step is realized.

Features at the mounting stage (development method based on a combination of abstract components) The business cooperation system 1 of the present embodiment has a structure as shown in FIG.
It has a computer screen state transition function 5 as a general-purpose application component, and also has a detailed access control function 2 essential for organizing the operation authority and range of each user on the Internet 6 and the value of input information as a general-purpose component. In addition, it also has a general security function 7 on the Internet and a database function 8 for each system as advanced general-purpose components.

The business cooperation system 1 of this example and a general AS
P (Application Service Pro)
The difference between this method and the system construction method is that it is not an ASP that develops each system incorporating individual specifications and rents and runs the system, nor is it an ASP that provides a single package in a customized manner. In other words, it provides a “third solution”. That is, the above A
Despite having SP-like elements, state transition machines, access control parts, and data store functions are prepared as abstract parts for general use independently of the application domain. This is an approach to map the context of the operation business domain to a computer through the implementation of.

[0038] The approach is fundamentally different from that of the current ASP service provider, which makes minor changes and additional functions to existing applications incorporating the context of the application domain.

With this approach, it is possible to apply the system of the present example and the services provided thereby to more business domains.
In addition, the reusability and applicability of the parts once prepared are dramatically increased. Until now, the “ASP business that customized general-purpose software” could be approached even in “business processing domain, where the mass market could not be expected and the development of dedicated software was necessary”. It becomes possible. This is a shift in thinking from an "application-based ASP business" to a "function-based ASP business".

Features of the entire process (Prototyping development method via the Internet (ISDM
I)) application software design and construction itself,
The actual work will be developed while taking the method of packing specifications via the Internet. The present invention relates to computer software and a construction method for realizing not only a network of services to be provided but also a construction procedure. (In addition, this method is referred to as “Interactive Software De
development Methodology ove
r The Internet (ISDMI) ”) Application screens in the process of production and their operability can be browsed and commented sequentially from the client, and the production status is simultaneously disclosed on the net. As a result, the communication cost and friction between the client and the creator are drastically reduced, and the productivity can be greatly improved.

2. Hardware resources required of the system user of this example The hardware configuration required to use the business cooperation system 1 between companies of this example is as follows, and these are the respective layers in the system 1 of this example. This is common to all of 1, 2, and 3. (1) System development contractor PC and browser software and communication line that can use the Internet (2) System development contractor PC and browser software and communication line that can use the Internet Computer server and general-purpose software required for system construction or external Utilizing the same resources (3) System users The target company is the system development contractor who called for the use, and the system development contractor himself. PCs and browser software that can use the Internet and communication lines. General-purpose software Technical features of this system Although the outline of the business cooperation system 1 between companies in this example has been described above, the technical features of the layers 1 to 3 provided by the system 1 are listed below.

(1) Layer 1: Simple and single data file sharing / exchange processing system between companies a) A data file sharing / exchange environment processing system (shared space CW) is provided across a plurality of companies.

B) The sponsoring company and the using company access the common CW using the ID / password issued in advance,
Perform file downloads and other operations.

C) The sponsor company can grant access authority (update / delete / download authority) for each file to each user company.

D) It has a function of sending an automatic e-mail notification to the concerned person every time a file operation occurs (each time an upload, update, or download operation occurs).

(2) Layer 2: Data file sharing / exchange processing system "taking into account state transition" between companies Layer 2 has the following technical features in addition to the functions of Layer 1.

A) How to proceed with business between companies on the net
It is defined as a sequence of "writing and reading to and from the shared information (data file)" rather than as a mere information exchange.

B) A mechanism (state transition machine) for giving a state to a posted data file is held, and a static data file is given a dynamic meaning in an application flow. As a result, it is possible to implement an application that embodies an inter-company collaboration system on the net without any programming work.

(3) Layer 3: Application system supporting business process between companies Layer 3 has the following technical features in addition to the functions of Layer 2.

A) It has both a program description rule in which input data undergoes a state transition every time it is written and a description rule for access control, and already possesses a specification base that can express almost any inter-company cooperation system as a general-purpose component. That you are.

B) Parts such as “access control parts”, “data sharing space”, and “state transition management parts” are held in advance,
It is premised on a software configuration and method for mounting as a general-purpose component and then creating a dedicated creation screen for each individual case.

C) While the above-mentioned general-purpose components are shared, the system itself for each case is different. In that sense, a plurality of individual systems are mounted on the common general-purpose components.

D) It is possible to implement a software construction method in which the developer contracts the specifications while checking the screen sample together with the developer.

E) With respect to individual systems constructed in parallel under various development contracts, so to speak, the use company including the contractor is conscious of only the mechanism used by himself, and the influence of other systems is not considered at the use level. The entire software configuration is used.

F) The screen via the network has different specifications for each development system, and the contents of the functions are also different for each programming design, so that the overall user operation is different.

4. Benefits of related parties by introducing this model The advantages of the related parties who use the business cooperation system 1 between companies in this example are listed below.

(1) Layer 1: Simple and single data file sharing / exchange processing system between companies (user advantage of using the system) a) Business conventionally realized by the e-mail broadcast "contact" function By realizing information communication and sharing between related parties by "publishing" in the common space CW on the Internet,
Improve the efficiency of information communication and sharing work.

B) By utilizing a mechanism for controlling access to shared information, information contact / sharing destination selection can be realized by a single "information posting" process.

C) By browsing the download history and using the automatic e-mail transmission function, it is possible to grasp in real time whether the contact / shared information has been browsed from the other party.

Conventionally, it has been attempted to satisfy this requirement with an electronic mail opening confirmation notification function.
Depending on the e-mail viewing environment of the source and destination of the information,
Whether the transmission of the opening confirmation notice is affected is affected, and as a result, it is not possible to confirm whether or not the other party has viewed the contact / shared information only with the opening confirmation notice.

D) The confidentiality of the contact / shared information can be ensured by using the authentication function using the ID / password for the common space CW and the encryption function.

(2) Layer 2: Data file sharing / exchange processing system "taking into account state transition" between companies (user advantage of system use) In addition to the advantage of layer 1, the following advantage can be obtained.

A) A function equivalent to an information communication / sharing application between companies can be obtained without any programming work.

B) The actual use environment is no different from the normal file upload / download, and there is no need to learn specific operation procedures and the like when using the application.

(3) Layer 3: Application system that supports business processing processes between companies Advantages of system development contractor When it is desired to construct a business system that extends between companies or a company system utilizing Internet technology, business requirements and functions are required each time. The process of compiling requirements and compiling specifications is indispensable. With this system, it is possible to sort and combine general-purpose system parts on the basic Internet, and to specify individual requirements through specific screens on the Internet. In the process of finalizing specifications with developers, the production process can be checked each time, and the difference in recognition between the specification request and actual construction can be minimized.

By performing a design procedure on a general-purpose component on which individual specifications are tailored to each business, it is possible to reduce the development cost per developer contractor, and simultaneously design requirements. By deviating from the above procedure and building the requirements while creating them specifically on the screen via the Internet, the system construction period can be significantly reduced.

Also in the system operation stage, it is possible to operate the developer on a loan basis and to operate the fixed-price inexpensively, and also to reduce the cost of changing the specifications due to the sophistication of general-purpose parts per person. .

Advantages of the System Development Consignor a) Rather than designing individual requirements from the beginning, a framework is constructed from a combination of general-purpose components, and individual requirements are confirmed and confirmed while showing actual screens via the Internet. It is possible to reduce the development cost per project, and thus the service cost.

B) As a prerequisite for individually developed components, by mounting general-purpose components at a lower level or higher, the system can be operated on the same system base in terms of system operation, and the operating cost per case can be reduced.

System User Benefits A system constructed based on the present system is a system for use on the Internet, and if it has a general communication environment and computer conditions, it is possible to participate and use immediately.

Next, a specific embodiment of the present system 1 will be described.

5. Conceptual diagram between layers on implementation First, with reference to FIG. 4, general-purpose modules on implementation between layers 1, 2, and 3 in the business collaboration system 1 between companies of this example and their relationships will be described. I do. In the system 1 of this example, the individual requirements of the inter-company cooperation system are implemented by combining general-purpose components at the following levels. In other words, the present system 1 provides a "real-world modeling technique / tool", "implementation methodology / means" and "operating environment" in unified manner, and also provides a prototyping development technique (ISDMI) via the Internet. To increase the overall actual work efficiency.

(Explanation of General-Purpose Components) This is a function that controls the entire infrastructure of the common space infrastructure system 1. As shown in FIG. 4, the entities are a web server 11, an e-mail server 12, a data storage space (database) 13
And an I / O control unit 14, which provides an operating infrastructure for an individual use environment implemented on each layer. By sharing and using this infrastructure from each individual use environment, it is advantageous in terms of construction cost and period as compared with a case where each individual environment is independently constructed.

Data Inclusion Module Group 15 This is a function part for encrypting data exchanged on the system 1 and this function is shared and used by all layers.

Access control module group 16 This function provides security-related services such as access control on the system 1. A user ID and password authentication function 17, a function 18 for mapping between “authenticated ID” and “accessible data and operable functions”, and an access log of data / functions of the present system are generated. It consists of a function 19 to be presented. This function is also shared from all layers. In addition to the authentication using a simple ID and password, the authentication function has a certification authority base for electronic authentication (server authentication, client PC authentication) and data encryption, and is provided according to the business requirements of the user. I do. In addition, according to the request of the user company, the authentication infrastructure such as card authentication and fingerprint authentication will be improved to improve the level of general-purpose parts.

Communication service 20 This function manages the communication service infrastructure on this system. It consists of an e-mail automatic transmission function activated by the occurrence of a specific event as a trigger, and an HTML-based data upload / download function. This function also
Shared from all layers.

State transition machine 21 This function provides a state transition service on the present system. Layer 2 provides a state transition environment independent of the data itself, and layer 3 provides a state transition environment integrated with a dedicated GUI screen and data.

In the present system, the driving elements of the state transition are decomposed into the following two types, and a business process in the real world is projected on a computer by a combination thereof. By analyzing and returning the user requirements of this system along with this element decomposition, it becomes possible to directly determine the business requirement analysis-the process of constructing the real environment, and the Internet-based Proto Timing Development Method (ISDMI) environment described later In addition to this, it is possible to drastically reduce the time and cost for implementation of business requirements and application construction work.

(A) State transition triggered by external I / O to this system a) Specific event executed by one or more users This is the state when the user explicitly performs some operation. This is a case where a transition occurs. For example, when a specific user (or a plurality of users) downloads / uploads a specific file (group) or presses a specific button.

B) A specific event that occurs independently of a human operation This is not a user operation as described in (A) above, but rather, for example, when a specific date and time has arrived, or when a specific This is a case where a state transition occurs when time elapses.

(B) State Transition Triggered by Satisfaction of Specific Condition of Data Content in the System This is a case where a state transition occurs when data content satisfies a specific condition. For example, in an environment where the inventory quantity is a data, the automatic order processing is driven when the inventory quantity falls below a preset level.

This event occurs only in layer 3. This is because the layer 2 does not refer to the contents of the data. Therefore, for business requirements that cause a state transition based on the content of data, the mechanism of Layer 3 is presented to the user.

The number of stages of each state and the name of each state to which a transition is made by the triggers (a) and (b) are different for each requirement. In layer 2, the number of stages and the names of the states can be easily set on a GUI basis, and applications can be generated and used without programming.

Application Repository / GUI
The control module 22 is a service that provides an application / GUI component on Layer 3 in the present system. The application implemented in layer 3 is implemented by combining the functions provided by this service.

Others Various platforms required for data transfer between companies are prepared, and ED
Includes I transmission function, data item association mapping function between companies, and FTP transfer support. In addition, a system that allows browsing of the mailboxes of many Internet provider services on the Web, that is, various functions aimed at completing business on the Internet, such as the Web mail infrastructure, will be made into general-purpose components according to the requests of system development contractors. I'm trying.

6. Example of environment using this system: Layer 1 A specific example of the environment of Layer 1 will be described with reference to FIGS. Layer 1 has no elements to be customized for each individual case, so the screens shown in FIGS. 5 to 8 are not examples but are determined functions themselves.

By referring to this history, it is possible to check at a glance whether or not the shared file has reliably reached each user.

Note that the "Refresh AccessLogs" button 46 is pressed to update the history to the latest state.

7. Example of environment using this system: Layer 2 A specific example of an environment of Layer 2 will be described with reference to FIGS. In layer 2, a “state transition” element of an individual requirement is added to the file exchange / sharing environment. Therefore, the usage method / screen described below is an application example of the system 1 of this example at the layer 2 level. However, no programming work occurs, and the environment can be obtained by performing “environment setting” of the system 1 on a GUI basis.

(1) System Background of Application Example In this example, the system 1 of the present example is applied to a business form in which a mechanical parts manufacturing company outsources scrap scrap to a trading company. That is, the mechanical parts manufacturer notifies the trading company of the item / volume to be scrapped and the collection frequency, and the trading company presents an estimate of the collection cost.

That is, in consideration of the estimated amount of money, the mechanical parts manufacturer makes a decision on which item is to be picked up and how much, and notifies the trading company. Next, the trading company notifies each scrap vendor of the final transaction request result of the mechanical parts manufacturer.

The business form of this example is a form in which the contact work includes a part of the contact sharing work. Although the development of web-based dedicated applications is also a prospect, there is a requirement that we do not want to invest in systems that exceed the human costs of the work currently performed by facsimile. Therefore, dedicated GU
The system investment including I is not implemented, and the implementation is made by the service of this layer 2 which combines the file exchange and the state transition machine. The purpose of applying IT to the business form in this example is to increase the efficiency and speed of communication and information sharing between related parties.

(2) State Analysis and Screen Flow In this case, the work proceeds by sharing the Excel file “scrap.xls” among the manufacturing company, the trading company, and the scrap company. In the course of business, this file keeps multiple states. The system 1 at the layer 2 level has a space on the net for sharing “scrap.xls” between related parties, a function that allows related parties to recognize the “state” of this file, and It has a mechanism to change the "state" of a file by an operation given to the file by a related person. In this case, there are the following four types of states of “strap.xls”. (Note that the log-in function for the common space CW uses the same mechanism in the case of the above-mentioned layer 1, so the description is omitted.) Scrap item / volume / collection frequency presentation state (FIG. 9) As a starting point, the parts manufacturer notifies the concerned parties of information on scrap products symmetrical with respect to the takeover request. The actual operation uploads an Excel file (scrap.xls) in which the parts manufacturer has written the information of the request for collection on the common space CW provided by the system 1. At the stage when the file is uploaded, this file is "Scrap item, volume, collection frequency presentation state"
Becomes FIG. 9 shows a screen display example of the component manufacturer side terminal in this state.

The scrap item pickup price offer state (FIG. 1)
0) With respect to the collection request information provided by the parts manufacturer, the trading company presents a collection price. Specifically, a trading company downloads “scrap.xls” posted on the book space CW, inputs a pickup price in a corresponding location, and uploads a file to the book space again. At the stage where the trading company uploads this file, this file becomes “Scrap item collection price offer state”.

Confirmed pickup request notification state (FIG. 11) In consideration of the pickup price information presented by the trading company, the parts manufacturer selects a picked-up item and notifies the trading company and each scrap company. Specifically, "scr" posted on this space
ap. “xls” is downloaded by the parts manufacturer, a symbol such as “○” or “X” is given to a corresponding location in the file, and the file is uploaded again to this space. At the stage when the parts manufacturer uploads this file, the file becomes "confirmed takeover request notification state".

Receiving Request Confirmed State (FIG. 12) In response to the finalized collecting request notice presented by the parts manufacturer, the trading company and each scrap collecting company confirm the contents and accept the collecting request. More specifically, a trading company and a scrap collection company download “scrap.xls” posted on this space and confirm the contents. Thereafter, the trading company and the scrap trader press the "confirm" button that has appeared on the system. This file appears when the system 1 detects that the state of the file has been changed to the “requested request confirmed state” when the trading company and the scrap collecting company press the “confirm” button.

When the shared file is in this state, one cycle of the operation is completed. When a parts manufacturer implements a new scrap product takeover request (specifically,
When the parts manufacturer overwrites and uploads the shared file), the shared file is again in the “scrap item / volume / collection frequency presentation state” described above.

(3) Others The setting items necessary for obtaining the above environment are as follows. Each setting item can be operated from a PC on a GUI basis, and does not require any programming.

[0110] Login ID, password,
Setting of E-mail Address Setting of Shared File Status (Registering the Four State Names) Operating Authority Setting of Each ID for Each State The operating authority of each ID in each of the four states is set. For example, when a file is in the “Scrap item / volume / recovery frequency presentation state”, only a trading company can upload data. Only the parts manufacturer can do it.

Transition condition setting for each state An event when each of the above-mentioned states transitions to the next state is set. For example, when the file is in the “Scrap item / volume / collection price offer state”, the state of the file changes to “Scrap item offer price offer state” by executing the data upload by the trading company, and so on. is there.

Setting of Automatic E-mail Notification Guidance For each of the above-mentioned events (data upload / download), the function of transmitting automatic e-mail guidance by this system is set.

8. Environment example using this system: Layer 3 A specific environment example of Layer 3 will be described with reference to FIGS. In Layer 3, an application is constructed by combining general-purpose components for each individual case.
(However, the framework of the information disclosure / update / view / deletion functions is retained as it is.) (Case 1: Shipment schedule) (1) System background of this case This case is a trading company and shipping company The ship allocation schedule and operation information on the screen accessed via the Internet.

In other words, “Space No” and “Workspac”
e) Register as a pair and set specifications so that updates can be made as needed.

In the menu of each function, the shipping company can use all the update / browse / delete functions, starting from the release of the shared information. As shown in FIG. 14, these functions are activated by clicking “public”, “update”, “view”, and “delete” buttons 51 to 54 displayed on the screen. Each trading company that views information can only use the “view” function. That is, as shown in FIG. 15, a "Browse" button 5 is displayed on the screen as a function button.
Only 3 is displayed.

(Function Selection Screen) Release (FIG. 16) With this function, new ship schedule information can be posted. The shipping company can be entered, and by clicking the "Post" button 35 after the entry, a transition is made to a detailed registration screen, and a new ship schedule and departure schedule can be disclosed to the viewing trading company.

After the registration is completed, the participating trading companies of the present system can browse within the operation range of the shared information browsing described below.

Update / confirmation of shared information (FIG. 17) This is selected when updating the data of the already registered ship operation schedule. In principle, the shipping company can update / confirm operations. Click the "Update" button to change the screen and update the date schedule. After the data is input, when the user selects the confirmation screen, the user can select whether to disclose as updated status information (with unconfirmed) or to disclose as confirmed information (final schedule).

Browsing of shared information (FIG. 18) The shared information of each of the determined and updated states at the present time can be browsed. For shipping companies, all information is available for trading companies under disclosure conditions in accordance with the shipping company settings.

From this screen, data acquisition (downloading) of operation data becomes possible, and data extraction becomes possible separately so that it can be taken into the in-house system of the participating company.

Shared information clear This function is selected when the shipping company wants to delete the shared information. After receiving a warning message such as a confirmation message, the right holder instructs data clear.

Maintainment of Common Space Participating Companies In principle, shipping companies can perform maintenance. A master maintenance screen for the contact of the trading company in charge of notification of e-mail, facsimile, etc. for each browsing range setting, various data entry updates, and new registrations for each trading company.
At the same time, it becomes possible to perform master registration when controlling the authority to update shared information within the shipping company. There is also a screen for setting an ID and a password for a trading company registered as a new space information sharing destination.

Unique Functions of the Space The unique functions required differ for each existing in-house system of the shipping company actually used and the trading company provided by the shipping company. The extracted data format, data type, and the like are parts that are individually created for each user company, and in that respect, they can be said to be parts that are individual differences in screen specifications after login.

(Case 2: Negotiation of delivery date delivery destination) (1) System background of this case In this case, in order to procure raw materials such as aluminum ingots of a certain manufacturing company and adjust the delivery destination and delivery date, we agreed with the delivery trading company. This is an example of building a negotiation business on the Internet. The contents of the process, from regular announcements of raw material quotas to trading company counters and final decisions on destinations and delivery dates, are to be digitized, leading to more efficient operations for both manufacturing companies and trading companies.

(2) General-purpose parts and individual parts in this system (general-purpose parts) Access control function: Detailed control of browsable information for each trading company Security function: Encryption, user setting, ID, PA
SSWORD management Database function: Input data and various master information of manufacturing companies and trading companies Screen / state control function: All function infrastructure necessary for "posting / sharing information" such as information input / update / browsing / deletion (general-purpose parts Login function Announcement of input for allocation of raw material handling, input of trading company counter, final confirmation, etc. Notification settings such as finalization For each function selection screen, save the state transition of various writing of input data, and screen associated with button operation Development (individual parts) Screen setting of "part that presents the information itself" Multi-function data extraction function for manufacturing companies and trading companies to pass data to each company's in-house system. Other functions that can be added by (Contents realized on the screen based on individual parts) And screen expansion associated with the button operation,
Although the functional aspects are general-purpose components, the screen settings differ depending on the individual contractor.

Buttons for taking out data necessary for each user on each screen and programming design associated therewith The method of notifying each company is different for each user. The display of the corresponding amount is displayed in dollars in addition to the Japanese yen display, and the bilingual notation is also reflected in the extraction data. (3) Screen flow of specific functions As with the first ship assignment schedule, the main screen where functions can be selected is This screen is displayed immediately after the trading company as a manufacturing company / utilizing company logs in to this system with its own ID and password. Similarly, the participating trading companies will be authenticated with the login name and password given by the manufacturing company that is the system development contractor, and only those who have obtained this certification will be able to use the service (the manufacturing company, that is, the system contracting company). Depending on the setting of the seller, the browsable range and contents of each trading company may be possible).

After receiving the authentication, the operation selection screen to be performed this time is displayed, and the shared information in the “Workspace” column is selected (in the case of the reference diagram, “Aluminum metal, delivery destination / delivery date adjustment” is selected), and the content is viewed. ·input. “St” on this screen
In the "atus" column, all participants can check the current adjustment progress.

The manufacturing company previously sets a shared space for exchanging information on the Internet, that is, a “procured material and its delivery destination / delivery date” pattern to “Space”.
It is registered as a “Workspace” pair, and specifications are set so that it can be updated as needed (FIG. 19).

(Function Selection Screen) Disclosure (FIG. 20) This is a function for notifying each trading company of a new raw material procurement quantity and a desired delivery date for each business site of the manufacturing company. A manufacturer can be input, and after inputting, a transition to a detailed registration screen is performed by a “disclose” button. Notify / disclose the new allocation request and the contents of the tender notice to the trading company that has been permitted to browse. Specifically, after filling out the input sheet, each trading company can browse the information via a confirmation screen.
Participating trading companies can browse through the operation of viewing shared information in the following sections, and the screen contents differ depending on the settings of the manufacturer.

Update / confirm shared information (see FIG. 21 for the manufacturing company screen and FIG. 22 for the trading company screen) Correction / final assignment finalization based on the registered contents of procured raw materials and their delivery destinations / delivery dates To be selected when When the manufacturer performs the update / confirmation operation, after the screen is changed by the "update" button, the delivery destination, the desired delivery quantity and the desired delivery date can be updated. After inputting the data, if the user selects the confirmation screen, the user can select any one of "disclose as updated information", "disclose as fixed information", and "return to updated screen".

When the same screen is opened on the trading company side, the contents of the notification of the allocation of the manufacturing company are displayed on the upper part of each column, and the trading company representative enters his / her request in the counter column below it and goes through the confirmation screen. This is the counter update information for the manufacturing company.

The manufacturer can correct the contents on the same screen in order to notify the counter information of each trading company of a different update or final confirmation, and finally select “disclose as final information” at the manufacturer. Is replaced with the final assignment notification.

[0137] In addition to the fact that the manufacturer always asks for the allocation, if the tender is announced by the new shared information disclosure in the above section, the trading company enters the bid on this screen and the manufacturer reports the successful bid result. It can be used for flow.

Browsing shared information (the manufacturing company screen is shown in FIG. 23,
(Refer to FIG. 24 for the trading company screen). All information about the manufacturing company,
It can be viewed under the disclosure conditions according to the settings of the manufacturer. From this screen, it is possible to acquire (download) the data in the data format of the data being determined or adjusted, and it is also possible to separately take out the data so that it can be taken into the in-house system of the participating company.

Clear shared information Select this when the manufacturer wants to delete the shared information. After receiving a warning message such as a confirmation message, the right holder issues a data clear instruction.

Maintenance of Common Space Participating Companies In principle, the shipping company can perform maintenance. A master maintenance screen for a trading company contact, which is a notification destination for e-mails and faxes, for each browsing range setting, various data entry updates, and new registrations for each trading company. At the same time, master registration can be performed when controlling the authority to update shared information within the shipping company. There is also an ID and password setting screen for a trading company registered as a new space information sharing destination.

This unique space function is different for each existing in-house system of the manufacturing company actually used and the trading company provided by the shipping company. It is a part that is created individually for each user company, such as the data format and data type to be extracted, and in that respect, it can be said that this part is an individual difference in the screen specification after login. In addition, the final allocation quantity for each trading company and the display of the amount corresponding thereto correspond individually to conditions such as foreign currency notation.

(Other Embodiments) The case where the system of the present invention is applied to each case has been described above. However, these cases are merely examples, and the present invention can be similarly applied to other businesses. Of course.

Further, screen display examples in each of the above cases,
The operation procedure is also an example, and other screen display forms,
Of course, an operation procedure may be adopted.

[0144]

As described above, according to the system of the present invention, there is no need to transmit data to each business participating company as compared with the current information exchange means via an e-mail attached file. Communication can be executed rationally. In addition, by using the automatic e-mail function or referring to the history log, it is possible to easily confirm whether or not the transmitted data has been viewed / not yet viewed by the other party. Furthermore, by setting the authority for uploading and updating data for each participating company, there is a requirement that data contents change after sending data, and a requirement to carry on work by bringing information between multiple companies For example, it is possible to obtain an environment for implementing a complicated information exchange / sharing system between companies at low cost and quickly.

Further, according to the data file sharing / exchange system in consideration of the state transition between companies and the business cooperative system provided with the same according to the present invention, it is possible to simply lend a space for installing shared information. Instead, it is possible to support processing in which the meaning of the data file changes as the business processing progresses. Therefore, it is possible to add an “application software” element that cannot be obtained by simple data file sharing / exchange operations to data file sharing / exchange operations between companies, and as a result,
Get the application "without developing the application." Therefore, the effect of dramatically reducing the cost for obtaining the same effect as the current application development can be obtained.

Further, according to the system of the present invention, operations on data can be performed by “open”, “update”, “browse”, “delete”
Since these functions are implemented as general-purpose components, seemingly complex business processes can be simplified with a unified framework, and exist as an infinite number of patterns. Individual system requirements can be reduced to a simple combination of functions and elements.

Also, the computer screen has a state transition function as a general-purpose application component. In addition, a detailed access control function necessary for organizing the operation authority and range of each user on the Internet and the value of input information is also a general-purpose component. Have. In addition, it also has a general security function on the Internet and a database function 8 for each system as advanced general-purpose components.

Therefore, the system of the present invention is not an ASP which develops each system by incorporating individual specifications and lends and operates the system as in a general system construction method.
In addition, it is not an ASP that provides a single package in response to customization, but can provide a so-called “third solution”. As a result, while having an ASP-like element, the state transition machine and the access control parts, and the data store function are prepared as abstract parts in a general purpose independently of the application domain, and the combination of the parts and An approach can be adopted in which the context of the operational domain is mapped to a computer through implementation on the screen display.

With this approach, it becomes possible to apply the system of the present invention to more business domains, and the reusability and applicability of the components once prepared are dramatically increased. Until now, the “ASP business that customized general-purpose software” could be approached even in “business processing domain, where the mass market could not be expected and the development of dedicated software was necessary”. It becomes possible.

In addition, if the system of the present invention is used, the design and construction of application software itself,
The actual work can be developed while taking the method of packing specifications via the Internet. In other words, there is an effect that computer software and a method for constructing the same can be realized not only in providing the services to be provided online but also in the construction procedure simultaneously.
