The user interface information storage means (hereinafter, referred to as UI information storage means) 24 stores user interface information (hereinafter, referred to as UI information) indicating a mode of processing and / or shaping of the result of the business process, as a request source. Storage means such as a hard disk device or a memory device that stores in advance for each client or for each group to which the client belongs. When the client is a person in a company, for example, there are jurisdictions such as branch offices and sales offices of the company, departments such as divisions and departments in the company, and the client is an individual customer. May include the client's age, gender, location, etc.

The WWW (World Wide Web) server 25
After the data conversion by the data management server 21, the business application layer 12 is caused to execute the business process according to the request, and the UI server 23 processes and / or processes the data.
Or an I / O server that sends the formatted business process result to the client that sent the request,
It is realized by executing a program describing such a function on one or a plurality of computers.

Further, in the first embodiment, W
The WW server 25 sends a request from the client terminal device 2 via the data management server 21 to an HTTP (Hype
r Text Transfer Protocol) and CGI (Common
Gateway Interface) is started and the business application corresponding to the request is executed by the business application layer 12,
The server also receives the result of business processing, which is an HTML (HyperText Markup Language) document processed and / or shaped by the UI server 23, and transmits the result to the client terminal device 2 that transmitted the business processing request by HTTP. It should be noted that the HTML document may include image data, script, and the like, in addition to page data in HTML.

FIG. 3 is a block diagram showing the structure of the database layer 13 in FIG. In the database layer 13 shown in FIG. 3, an abstract database server (hereinafter, referred to as an abstract DB server) 41 is a real database 43-i (i = 1 to N) which is a target of a command supplied from the business application layer 12. ) Is read from the abstract database 42, the command from the business application layer 12 is converted into a command for the real database 43-i according to the specification of the real database 43-i, and the converted command is converted into the real database 43-i. -I server.

After issuing the converted command to the real database 43-i, the abstract DB server 41 acquires data from the real database 43-i in response to the command, and changes the format of the data to the real database 43-i. The server also converts the data into a predetermined single data format based on the specifications of 43-i and supplies the converted data to the business application layer 12.

The abstract DB server 41 is realized by executing a program describing the above functions on one or a plurality of computers. For example, ODBC (Open DataBase Connec
Describing the program of the abstract DB server 41 based on the specific DB, the abstract DB is managed without being aware of the difference between the database management systems managing the real DB 43-i. A server 41 can be created.

An abstract database (hereinafter, abstract DB)
42) is a database that stores the specification information of the real databases 43-1 to 43-N. The real databases (hereinafter, referred to as real DBs) 43-1 to 43-N are one or a plurality of databases that actually store data used for business processing. Note that the real DBs 43-1 to 43-
As N, a database having various structures other than a relational database or a structured database can be used.

For example, in the real DBs 43-1 to 43-N,
Only the data value is stored in association with the key, and the abstract DB4
2 stores the attribute of each data in the real DBs 43-1 to 43-N. The attributes of the data include the type of data, the state of the data (whether or not a value is determined), the logic for calculating the value, the relation between the data, and the like.

In other words, the database layer 13
The virtual database layer 51 converts a database specification into a single specification using B data 41, and the real database layer 52 includes an abstract DB 42 and real DBs 43-1 to 43-N.
Regardless of the database of any specification, the abstract DB server 41 functions as a database or a database group of a predetermined single specification as viewed from the business application layer 12 by the operation of the abstract DB server 41.

Next, the operation of the business processing system 1 will be described. FIG. 4 is a flowchart illustrating the operation of the business processing system 1 according to the first embodiment.

First, when a user who is a client of a business process operates the client terminal device 2, the client terminal device 2 transmits a business process request corresponding to the operation to the business processing system 1 via a computer network or the like. I do. In this embodiment, HTTP is used as the communication protocol.

At this time, for example, the client terminal device 2
However, by executing a program dedicated to specific tasks, the user,
Operate the request according to the program. Alternatively, the client terminal device 2 executes a WWW browser program, accesses a WWW page for a specific business in the WWW server 25 or the like of the business processing system 1 in response to a user operation or the like, and
Download HTML (Dynamic HTML) documents, etc.
The user performs a request operation on the WWW page.

On the other hand, the business processing system 1 stands by until a request is transmitted. When a request is transmitted from any one of the client terminal devices 2, it receives the request and executes the following processing. (Step S
1). At that time, the request is received by the data management server 21 of the I / O layer 11.

The data management server 21 of the I / O layer 11
In addition to receiving the request, it also receives the data attached to the request (request attached data)
The data format of the request attached data is checked (step S2). The data format at this time is the data type, the number, and the like of the request attached data, and includes the order of the request attached data when there are a plurality of request attached data.

As the request attached data, in addition to plain text and binary data, for example, a file format specific to an application such as Microsoft Word or Excel may be accepted.

That is, in accordance with the type of the received request, the data management server 21 requests the data format required for the request attached data, that is, the business application layer 12 requests the request attached data for the business processing of the request. The data format to be specified is specified, and the predetermined data format is compared with the data format of the received request attached data for inspection. The information in the predetermined data format may be stored in the data management server 21 in advance, or may be stored in the database layer 1.
3 and, if necessary, the data management server 21
May be read.

After the inspection, if the data format of the received request attached data is not the predetermined data format, the data management server 21 converts the data format of the request attached data to the predetermined data format (step S3).

At this time, when the number of the request attached data is insufficient or the data format of the request attached data cannot be converted to the predetermined data format due to an unknown data type. Then, the data management server 21 transmits an error message to that effect to the requesting client terminal device 2 (step S4), and ends the processing for this request. Upon receiving this error message, the client terminal device 2 displays the error message to call attention to the user.

On the other hand, when the data format of the request attached data is converted to the predetermined data format, the data management server 21 associates the converted request attached data with the request and stores the request attached data in the request attached data storage means. 22.

When the data format of the received request attached data is the predetermined data format, the data management server 21 associates the request attached data with the request without performing any conversion. It is stored in the request attached data storage means 22 as it is.

The data management server 21 transfers the received request to the WWW server 25 by HTTP (step S5).

Upon receiving the request, the WWW server 25 activates a predetermined CGI (step S6),
The business application according to the request is executed by the business application layer 12 (step S7).

At this time, the business application layer 12
For example, in the case of different programs for each business process such as warehousing process, warehousing process, inventory check process,
The CGI of the WWW server 25 executes a program describing a business process according to the request. Alternatively, in the case where a plurality of business processes are executed by one program in the business application layer 12, W
The CGI of the WW server 25 supplies the type of the requested business process as an argument, and executes a program including a description of the business process in accordance with the request.

Then, the business application layer 12
When the business process specified by the request is executed, the result is transmitted to the I / O layer 11 (step S8). At this time, the business application layer 12 uses the JAVA (trademark)
Technology and. The business process may be performed in cooperation with the client terminal device 2 using the NET technology.

As the result of the business process, there is a notification that the business process has been successfully completed, output data (data of a calculation result, data read from a database) by the business process, and the like.

Upon receiving the result of the business process, the UI server 23 of the I / O layer 11 specifies the client, that is, the user who is the request source of the business process, and determines in advance the user or the group to which the user belongs. The designated UI information is read from the UI information storage unit 24, and based on the UI information, the received business process result is processed and / or shaped (step S9), and the processed and / or shaped business process is processed. The result is supplied to the WWW server 25 (step S10).

For example, when data A, B, and C are obtained as a result of business processing, data unnecessary for business (for example, data C) of the user or the group to which the user belongs is deleted. For example, data of another format (for example, data obtained by performing predetermined calculations on the data A, B, and C) of the user or the group to which the user belongs is generated. That is,
In the UI information, among the obtained data, data to be left as a result of business processing for the user is set,
Data conversion formulas, data display formats, etc. are set.

The UI information includes the above-described format of processing and / or shaping for the result of each business process.
It is set for each user or group to which the user belongs.

The method of specifying the requesting user may be any method. For example, when the client terminal device 2 attaches an identifier (user identifier) unique to the user to the request and the data management server 21 receives the request, the client terminal device 2 attaches the request identifier to the request, and associates the request identifier with the user identifier. Notify the UI server 23 in association with the
The server 25 executes the business processing by the business application layer 12
The request identifier is also passed to the business application layer 12 when the
Sends the result of the business process with the request identifier to the UI server 23, and the UI server 23 associates the request identifier previously received from the data management server 21 with the user identifier of the requesting user. The requesting user may be specified from the information of the request and the request identifier attached to the result of the business process from the business application layer 12.

Further, at this time, the UI server 23 transmits the HTML including the result of the business processing after the processing and / or shaping.
A document may be created and supplied to the WWW server 25. In that case, the layout of the HTML document may be set in the UI information.

When the WWW server 25 receives the result of the business processing after the processing and / or shaping, the WWW server 25 transmits the result of the business processing or an HTML document including the result to the client terminal device 2 which has requested the business processing by HTTP. It transmits (step S11).

When the client terminal device 2 that has transmitted the request receives the result of the business process corresponding to the request, the client terminal device 2 displays, saves, or prints the received result of the business process. At this time, the result of the business process
It is displayed, saved, or printed as processed and / or shaped by the UI server 23.

At this time, the client terminal device 2 executes the WWW browser program to execute DHTM
The request is sent according to a script in the L document, and the result of the business process of the request is HTML
When sent as a document, the result of the business process is displayed based on the HTML document according to a WWW browser program.

Thus, the client terminal device 2
Receives the request from the business processing system 1
Executes the business process corresponding to the request, and transmits the result of the business process to the client terminal device 2.

Next, a description will be given of an operation for executing access to a database when executing the above business process.

The business application layer 12 executes the business process corresponding to the request when the database layer 1
When access to the database 3 is required, a command for a predetermined single-specification database virtually constructed in the database layer 13 is transmitted to the abstract DB server 4 of the database layer 13.
Send to 1.

At this time, the business application layer 12
With a set of general-purpose tools that implement an interface with this predetermined single-specification database,
The business application layer 12 may transmit and receive commands and data to and from the abstract DB server 41 using the general-purpose tool group.

Upon receiving a command supplied from the business application layer 12, the abstract DB server 41 receives one or a plurality of real DBs 43-i as targets of the command.
(I = 1 to N) specification information (for example, real DB
The attribute data of each data in the real DB 43-i is read from the abstract DB 42, and the command from the business application layer 12 is read according to the specification of the real DB 43-i.
The command is converted into a command for 3-i, and the converted command is issued to the real DB 43-i. If the real DB 43-i is a relational database, the converted command is SQL (Structured Query Language).
The command of e) may be used.

When the real DB 43-i receives the command, the real DB 43-i analyzes the command and performs processing (addition, change, reading, etc.) according to the command.

[0133] Then, when processing such as data reading is performed, the real DB 43-i transmits the data to the abstract DB server 41. The abstract DB server 41 acquires the data and converts the format of the data to the actual DB 43.
Based on the specification of -i, the data is converted into a predetermined single specification data format, and the converted data is supplied to the business application layer 12.

As described above, the abstract DB server 41
B43-1 to 43-N are transferred to the abstract DB42.
The database layer 13 functions as a database of a predetermined single specification when changed based on the specification information of each real DB 43-i registered in the database and viewed from the business application layer 12.

As described above, the I / O layer 11, the business application layer 12, and the database layer 13 are realized by independent programs, and the business application layer 12 does not directly receive a request from a client. The database layer 13 is regarded as a database having a predetermined single specification, and inputs and outputs commands and data.

In the I / O layer 11, the data management server 21 and the UI server 23 perform data processing for each client, so that the business application layer 12
Need not perform those processes.

In the database layer 13, the abstract DB
Since the server 41 absorbs the difference between the specifications of the real databases 43-1 to 43-N and allows the database layer 13 to be regarded as a single-specification database, the business application layer 12 Command and data may be input / output to / from the device.

As described above, according to the first embodiment, the I / O layer 11, the business application layer 12, and the database layer 13 are separated from each other. (That is, the part processed by the I / O layer 11)

According to the first embodiment, the I / O
The data management server 21 of the layer 11 receives a business process request from a client at a stage prior to the business application layer 12 and checks the format of data attached to the request. If the data format is not the predetermined data format required for the business process by the data management server 21, the business application layer 12 converts the data format to the predetermined data format and uses the data converted by the data management server 21. To perform business processing. Thereby, the conversion process of the format of the data attached to the request from the client can be separated from the business application layer 12 and the load concentration on the business application layer 12 can be suppressed. In addition, since the I / O layer 11 is separated from the business application layer 12, creation of the business application layer 12 is simplified and productivity is improved.
Only by changing the / O layer 11, the style such as the display screen for the client can be changed, and the maintainability is improved.

Further, according to the first embodiment, the I / O

The UI server 23 includes a UI information storage unit 24 that stores in advance, and the UI server 23 processes and / or shapes the result of the business process based on the UI information. Thus, by simply adding or editing the UI information, the style of presenting the result of the business process can be appropriately set according to the client and the group to which the client belongs. It is easy to set the style and change the specifications of such style for existing clients.

Further, according to the first embodiment, I / O
In the O layer 11, the UI server 23 generates a result of the business processing after the processing and / or shaping as an HTML document, and the WWW server 25 transmits the HTML document generated as a result of the business processing to the business processing request. It transmits to the transmitting client by HTTP. Thus, the existing WWW server technology and WWW browser technology can be used for communication between the client and the I / O layer 11, and the system can be constructed cheaply and easily.

Further, according to the first embodiment, the data management server 21, the UI server 23, the WWW server 25
