Description

  The present invention centrally manages a group of electronic documents created, edited and referenced in a plurality of different facilities with a common software, minimizing server resources, reducing software development and maintenance costs, and further necessary. The present invention relates to a document management server system that facilitates information sharing between facilities according to the situation.

With the expansion of computer utilization technology, medical institutions such as medical care, nursing care, and welfare institutions, as well as educational institutions, administrative institutions, etc., aim to improve work efficiency and speed, instead of paper documents, The introduction of a document management server system using a computer is in progress. In medical institutions, medical records such as medical records such as doctors and nursing records, so-called electronic medical records, as well as medical instructions, are issued by doctors as electronic documents including the date and time of execution and the content of instructions to be performed. Based on this medical instruction document, the medical staff performs a medical practice. In nursing care facilities and welfare facilities, the digitization of documents such as personal information, nursing care plans, and nursing care records of care recipients is rapidly progressing. Educational institutions are beginning to manage student histories and attendance records, and computerized lecture records. Also in the government, the internal approval of the agency and the digitization of records of each case such as bidding are being promoted.
As a system for managing and processing such document data, techniques of Patent Documents 1 to 3 are known.

  Hospitals, nursing homes, schools. Because administrative functions differ in administrative institutions, the types of documents managed for operation are naturally different. Even if you take the same medical institution, for example, university hospitals and outpatient clinics, brain surgery and psychiatry have completely different document categories and items, and they are medical institutions of the same industry and business type. However, the types of documents and the items built in each document are usually slightly different for each individual medical institution. In addition, the types and items of documents need to change according to changes in medical care and social conditions. It goes without saying that educational institutions and administrative institutions with different industries have completely different types of documents and items.

  In a document management server system, a relational database is often used. It is indispensable to design the relational database item strictly in advance because it is difficult to change the item in the middle. If the items are different, the structure of the database is naturally different. Therefore, it has become natural that the document management server system for designing and managing the database is individually developed and operated. Therefore, it has been usual to have individual databases and individual document management server systems for each facility in the same industry as well as medical, education, and administration in different industries.

When a document management server system is installed for each facility, the following problems occur.
(1) Since each document management server system is one-item production for each facility, it takes a lot of time and money to develop and maintain software.
(2) Since the recording areas of the individual document management server systems are all separate, the compatibility is poor and they cannot be interchanged. Therefore, each system has a large recording area that is not used, resulting in unnecessary costs.
(3) Server management for each facility requires maintenance work on-site, and there is a considerable increase in labor costs and movement costs for standby maintenance personnel.
(4) In the same industry, it is sometimes necessary to share information between facilities, but sharing is difficult between different document management server systems.

There is also an ASP format that consolidates servers in a data center and provides document management services to customers via the Internet. This solves the problem (3), but assigns one corresponding server to one facility, and other problems are still unsolved.
A company called Salesforce.com has a huge data center (cloud) on the Internet, which allows office work such as sales, inventory management, and payment management of many client companies to be accessed from a browser such as a PC connected to the Internet. It provides a service in the form of SaaS. Although this form solves many of the problems described above, it is limited to office work related to corporate sales. This type of work is common to all types of documents and slips regardless of company, so if you set up the use of documents and items provided in advance for each client company, you can use them immediately. You can start. However, it goes without saying that document management such as medical care, education, and administration with completely different document structures is impossible on the same system.

  There is also a company called SAP. It is a collection of various management functions for the entire company such as cost calculation and delivery plan as well as sales, inventory management and payment management. Each company can easily construct a complex and huge company management system by selecting and setting necessary functions from among a myriad of provided functions. Although there are many advantages of this system, for the same reason, it is impossible to operate document management such as medical care, education, and administration with completely different document structures on the same system. In addition, there are actually subtle differences in the construction of documents, items, and processing procedures for each company, and it is difficult to operate with just a simple combination setting of the provided function menus. It is the actual situation that development of is necessary.

  The present invention was made in order to solve such conventional problems, and the object of the present invention is to have various document categories and their item-built configurations, even between facilities with different types of business and business types, By providing common document management means, document category definition means for each facility, item definition means for each document category, and document processing means for each facility, it is possible to provide document management services to multiple facilities using the same software on the same server. It is to realize software development, reduction of maintenance costs, cost reduction by accommodating recording areas, reduction of maintenance work costs, and easy information sharing.

The best mode for carrying out the present invention will be described.
An outline of the medical information sharing system of the present invention is shown in FIG. In hospital A, a document management server is installed and connected to a terminal PC group in the hospital via a LAN cable or a wireless LAN. The document management server of hospital A has a service socket called a web service (Web Service), and transmits and receives document data in response to a request from a terminal PC browser. It is connected to the Internet via firewalls and routers.

  In the care facility B, the terminal PC group is similarly connected to the LAN, but is connected to the Internet line through a router and a firewall. No server is installed in the care facility B, and the terminal PC transmits and receives document data to and from the server of the hospital A through the Internet line. The communication via the Internet is preferably communication with high security such as VPN connection, but may be encrypted communication such as SSL. As described above, a method of receiving a service via the Internet without having a server in its own facility is called SaaS (Software as a Service).

  School C is similarly connected to the Internet via a router and firewall. No server is installed in school C, and document data is transmitted and received in the form of SaaS to the server of hospital A through the Internet line using the browser of the terminal PC connected to the LAN.

  The staff of each facility above accesses from the PC in the facility, but patients, residents, users, etc. also access the document management server from their own PC via the Internet and authenticate with the assigned ID and password. And refer to and edit the document data about itself within the scope of permission. Sometimes, common patient information may be referred to from a medical institution belonging to a document management server separate from the document management server of FIG.

In order to manage documents of a plurality of facilities having different personalities with one document management server system, (1) a list of document categories used in each facility and management means for building up items in each document category, (2) Document processing means for processing various categories of documents and items used in each facility, (3) Document data recording means for recording and referring to various created documents, (4) Accessing users It is necessary to have each means group of user authentication and document access authority management means for each user that can authenticate and view, create and edit documents only within the permitted range.
Hereinafter, specific examples of the present invention will be described along each means group.

  FIG. 2 is a list of document categories used by each facility. Various document categories are used depending on the activities of medical institutions such as clinics, hospitals, nursing homes, and schools. In addition, even in the same medical facility type, a facility-specific document category is used in addition to a common document category. Each document category consists of items specific to that document.

3 and 4 are examples of document category item configurations. FIG. 3 shows a doctor record, and FIG. 4 shows a part of a patient's daily life level evaluation record. There are various types of items such as free description items, alternative items such as sex and selection from multiple levels, and integer values such as age.
As for the definition format of each item, a well-known definition format may be appropriately selected according to the characteristics of the facility and the specifications of the system used. As described above, various types of document categories and items built for each document category are used depending on the facility. In order to process these, document category definition means for each facility, items for each document category, and so on. A definition means is needed. Format data such as document category definition information such as document print format, data format such as data limit values, and item definition information is also variable-length data, but of course differs depending on the document category.
Normally, registration of format data is managed by another relation, and only the format data ID is recorded. However, if there are a wide variety of variations depending on the individual document, this format data is also recorded in the XML or JSON format file corresponding to each document, and the address to that file is recorded as well as the document content data. Also good.

The document category defining means and the item defining means for each document category are programs that define the document category and its items set according to the facility, that is, according to the accessing user, and are a medical institution, educational institution, administrative Data processing is executed in response to requests from users of other companies.
When a medical institution accesses a database, the database is browsed, edited, and processed through a program specific to the user of the medical institution. When an administrative institution accesses the database, a program specific to the user of the administrative institution is The database is referenced, edited, and processed through
Which program to apply to the user is selected and applied by the server authenticating with an ID, password, or the like.

Next, document data recording means for recording document data of various document categories having various item configurations will be described. Here, document data of two types of document categories, such as patient basic information and drug prescription in a medical institution, is taken as an example.
FIG. 5 represents each document data in a relational database format. In a relational database, individual items are recorded as fixed-length data, which enables high-speed processing. On the other hand, if the items are different, it is difficult to treat them as the same table (relation), so they become separate relations.

  6 and 7 represent the data of each relation in FIG. 5 in a format called XML and JSON. In the XML format and the JSON format, the data is a text file, and the length of the file is different. The item denomination is expressed by a tag indicated by <> in the XML format. In the JSON format, it is expressed in the format of “tag name”: “data”. Even if the data item structure for each department is different, all the data items of one document can be converted into one data file in XML format or JSON format. Even if the item structure and description format are different, if they are converted into XML files or JSON files, they are all just one variable length text file. Therefore, a fixed-length address indicating the recording location of XML document data or JSON document data may be stored in one relation cell.

The XML format can express a complicated data structure such as a nested structure or a repeated structure, and thus is highly versatile. However, it takes time to process, and it is uneconomical for data having a simple structure. In such a case, a structure in which “tag” and “data” are simply placed side by side with “:” in between, as in the JSON format, is often more efficient. Depending on the situation, both may be used properly. In the following, the XML format, which has become more practical, will be taken as an example, and the explanation will proceed. The same can be said for the JSON format.
It should be noted that the present invention can be implemented even in a document data file called CSV format in which values are separated by commas “,” or in which the document contents are written as text without any internal structure. Although included in the present invention, it is difficult to understand what each piece of data means, and it is difficult to create a search index.
In the embodiment, the variable length document content data is collected into one XML or JSON file. However, when the amount is long, it may be divided into a plurality of files and recorded. Further, it may be recorded as a plurality of variable length data for each content, such as document content data and document format.

Here, as shown in FIG. 8, a relation including a document ID, a creator, a creation date, a document category, and a fixed-length address indicating an XML text file as a document subject is considered. In this way, differences in the itemization for each document category are absorbed in the XML format, so that all document categories can be easily handled with the same relation. Such a database is called an XML relational database. In a practical system, if XML is text, processing will be slow, so XML text data is recorded as an object in internal representation (binary format) that can be processed by machine (XML object relational database XML Object Relational Data Base) ). In addition, an index for high-speed processing is prepared.
Thus, the server database has a plurality of data files recorded according to a predetermined classification.

In addition to the variable length document content data itself, information indicating the following document attributes is indispensable not only for medical institutions but also for education, administration, and companies. (1) What is the document related to, (2) Which category the document belongs to, (3) Who created it, (4) When it was created / edited .
The ID for identifying the case of (1) is a patient ID for a medical institution, a student ID for an educational institution, a resident ID for an administrative institution, a customer ID for a company, or a project ID. and so on. In any case, an appropriate ID may be selected as a group of documents in an environment where the document creation apparatus is used.
(2) The document category ID is a group of documents constituting the case and indicates the type of document. In medical, basic patient information, drug prescriptions, etc., in education, unit registration application, test results, etc., in government, family register copy, resident card, tax payment history, etc., in companies, transaction history, sales history, trouble history and so on. It goes without saying that the content and format described vary depending on the document category.
(3) The position, type of job, scope of responsibility, etc. vary depending on the staff. Needless to say, in addition to creating and editing unauthorized documents, reference is not permitted in some cases. It is indispensable in the operation of this document creation device to perform personal authentication with a password or the like and specify the access authority of the staff.
(4) The document creation date and time is often a problem due to the legal proof of the document, and must be strictly managed so as not to be falsified.

Information such as ID, document category, creator, creation / edit time, etc., as shown in FIG. It can be said that it is preferable. However, if the index of XML data that is the substance of variable-length document content data is substantial, in some cases, an arbitrary item indicating an attribute may be included in the variable-length document content XML data.
In FIG. 8, data in units of a horizontal series of document IDs includes (1) what kind of document the document belongs to, (2) which category the document belongs to, (3) who created the document, (4) Attribute information indicating when the document was created / edited is attached.

  FIG. 9 shows one preferred embodiment of the document management server system using the integrated document data recording means. The document processing means has a web service socket for each document category, and performs document data communication with the terminal PC. If there is a request from the terminal PC through each web service socket, the integrated document data recording means is searched, a list of document categories, a list of documents in the specified document category, and the document contents of the specified document Data is transmitted from the web service socket to the terminal PC. If there is a request for writing document data, the web service socket receives the document data from the terminal PC and executes writing to the integrated document data recording means. Thus, the integrated document data recording means functions as a data linkage bus between the web service processing modules (database bus). By using the web service, document data can be transmitted and received in the Internet standard format regardless of inside or outside the facility.

As shown in FIG. 10, in the document data recording means integrated in a multi-facility, the facility code for identifying the facility is necessary for the document data. However, the document data recording means is divided and managed for each facility. There is no need for a facility code. The configuration may be determined as appropriate in consideration of various conditions such as the amount of data and security.
Depending on the operating environment of this document creation device, it is useful to save the original document as a history so that the change history can be referenced at any time even if the document is changed or deleted.

  Conventionally, as shown in FIG. 11, department systems for managing different relations are created separately for each document category, and the whole system is configured by collecting these department systems. In other words, for each document category, a large number of department system modules comprising means for managing document data and means for processing the document data are combined, and the terminal PC is based on a communication standard such as HL-7. , Made a reference or write request. In this conventional method, it is difficult to handle innumerable document categories that differ from facility to facility as described above. Since many different relations and department systems that manage each of them are independent, it is difficult to centrally manage data, and searching across the data is extremely difficult. Another problem is that when someone opens a patient's chart, other users have limited access to the chart. In addition, software must be prepared for each department system module for each facility, and unified management is almost impossible and requires a large amount of development and maintenance costs. In addition, since the conventional department system individually manages data and inquires and responds to data in a format such as HL-7, multi-dimensional reference is extremely complicated. However, as in the present invention, if the data structure is unified, complicated references can be easily realized by hitting a SQL sentence once.

FIG. 12 shows the details of the document processing means of FIG.
The document processing means reads out the document data from the document data recording means (data file), displays the read document data in an easy-to-read form, edits and writes the document data, or creates a new document. Perform processing such as deleting a document. As shown in FIGS. 3 and 4, since there are a wide variety of document categories and item configurations, a document category defining unit for each of a plurality of facilities and an item defining unit for each of the document categories are provided. For each document category, as described above, a web service socket for transmitting and receiving document data to and from the terminal PC is provided. In addition, as will be described later, an access management means for each user using an access control table for each authenticated user is provided.
The server identifies the access from the client, and the document access management means for each user identifies to what extent the document category can be accessed. A function is provided that provides configuration item information of the document category to a data file accessible according to the accessing client, and performs data processing by applying document processing means (program) to the document.

When there is a request for transmission / reception of document data from the terminal PC, the user is first authenticated by inputting an ID or password or biometric authentication. Next, the access control table of the user is searched to check whether the access request is permitted for the patient and the document category. If not permitted, an error message to that effect is sent and no further processing is performed.
If the reference request for the document category is permitted, the document data is read from the document data recording means, and the document display is performed using the definition information of the document category defining means and the item defining means for each document category. After adjusting the appearance, it is transmitted to the terminal PC. If the write request is permitted, after confirming the consistency of the received document data by using the definition information of the document category definition means and the item definition means for each document category as necessary, the document data recording means Record.

  Here, the configuration of the document processing means as software is considered. Accepts the request from the terminal PC, checks whether the request is permitted, reads the document data from the document data recording means, uses the definition information of the document category definition means and the item definition means for each document category, and Processes such as adjusting the display format and writing edited document data in the document data recording unit are common processes regardless of the type of document category. This common processing may be defined in one place in the common document processing means. If the software is written in object-oriented programming, it can be defined as a common processing method for the parent object. In this way, it is not necessary to create separate department systems for each document category and to define similar processing separately for each department system as before, reducing software weight and reducing development and maintenance costs. can get.

  FIG. 13A shows the hierarchical structure of the document processing means. The lowest layer corresponds to transmission / reception of communication data, reading / writing of document data to / from a file, error processing related to them. The next layer corresponds to processing common to document categories based on the lowest layer functions such as user authentication, document display, and document editing. The highest level corresponds to processing specific to each document category, such as calculating the score of an item. In this way, all document processing functions may be combined into one software.

  However, document categories are completely different between medical institutions and educational institutions, and there are many unique processes. In such a case, when all the document processing means are integrated into one software, the software tends to be enlarged and there is a risk that the processing becomes heavy. Therefore, as shown in FIG. 13B, the document processing means is separated into a common document processing means common to each facility and a facility-specific document processing means (user-specific document processing means) unique to each facility. If necessary, both are combined to perform document processing. The facility-specific document processing means is not limited to a single unit, and a plurality of facility-specific document processing units may be prepared according to the document category and combined as necessary. The facility-specific document processing means for processing a document is not limited to a single module, and may be a combination of a module common to a plurality of document categories and a processing module unique to the document. If necessary, software may be divided and developed for each facility or document category group, and only necessary modules may be installed. It goes without saying that the discussion in this section is valid for any software that operates on the terminal PC side, such as server-side software, SaaS terminal, or client software.

  When managing document data across multiple facilities, the same subject may have document data at multiple facilities. For example, a patient living in a certain area is receiving treatment at a plurality of hospitals or clinics. If medical data from other medical institutions can be referred to with the consent of the patient, duplicate testing is unnecessary, which is useful for reducing medical costs and reducing oversight of information on important allergies and diseases. Helps improve. When referring to information on multiple facilities of the same target person, it is necessary to manage access authority to all document categories of all facilities for each individual user.

FIG. 14 shows an access control table that summarizes how much a certain user can access a document category.
As an example, the access authority management means of the present invention defines a range in which a user can access the database of the server with reference to the table of FIG.
The horizontal axis is the facility / document category, and the vertical axis is the unique ID to which the document belongs, such as patient number, student number, and project number. Since there are many cases where individual numbers are assigned depending on the facility, it is desirable to set a unique ID number such as a common number for implementation.
When starting up a computer or accessing a network, user authentication such as input of a user ID or password or biometric authentication is performed. If a user is specified, the data range that the user can access is also defined. For example, in FIG. 14, assume that the authenticated user is a doctor at hospital A. For patients in hospital A, reference / editing is possible for basic patient information and records at the time of first doctor visit. However, nursing records are for reference only because of different occupations.

Usually, the same access rights are often applied to patients related to the facility, but if special confidentiality is required such as celebrities and politicians (eg ID9567), only limited staff It may give true access and not allow other staff to access it. In this case, even doctors cannot refer to it at all.
For other clinics B and nursing care facilities C, only the patient / resident can be referred to only when the permission of the partner facility and the consent of the person in question are obtained. Other patient / resident documents are of course not accessible. Also, since it is not the staff of the facility, it is of course impossible to edit the document.
Currently, team medical care is provided, and many occupations are involved in treating a single patient. If you are suspicious of prohibiting access to only certain patient data within a medical institution, it is also effective to display a fake name or date of birth for medical staff who cannot tell the truth. It is. In addition, when a pre-registered facility staff accesses from outside the facility to which they belong, there is a risk of impersonation of the ID, so in order to avoid information leakage due to personal identification, display the patient name and date of birth, It may be ambiguous, such as initial display or age display.
In this figure, the access authority is defined for each document category. However, depending on the case, whether access is permitted may be specified at the item-built level in the document. When an access control table is actually created for all subjects, the amount of data becomes enormous. Therefore, it is usually necessary to compress the data amount by using a method such as setting a default value or overwriting an exception part. In short, when a specific user requests a reference regarding a specific target person, it is only necessary to reproduce the access control information necessary for the approval or disapproval.

  If a patient living in a certain region is receiving treatment at multiple hospitals or clinics, if medical data from other medical institutions can be referred to with the consent of the patient, duplicate testing is unnecessary and medical costs are reduced. As mentioned above, it is useful for improving medical safety as well as reducing oversight of important allergy and disease information. When document data exists in the same server of the present invention, since the user of the inquiry source is already registered, the access control table of the user exists, so the access right is set with the consent of the institution of the inquiry destination. do it. However, in many cases, it exists in another document management server system managed for each medical institution or group of medical institutions. In that case, since the user of the inquiry does not have user registration in the document management server system of the inquiry destination, the user is requested to make a user registration by telephone or e-mail, and the consent of the institution of the inquiry destination is obtained as well. Set access rights for each document category. In some cases, a list of organizations that can cross-reference in a region may be created, and user registration / access rights may be set in advance.

  In the conventional regional medical chart sharing system, (1) information extracted from the medical chart is stored in the regional medical chart sharing server to respond to the reference request. (2) The regional medical record sharing server manages only the authentication of the referral user, the medical institution where the patient is consulting, the ID there, and the document category list disclosed. Each medical institution responds to a reference request by a medical institution disclosure server that converts internal medical chart information into disclosure data in response to a reference request that has been authenticated by a regional medical record sharing server. Yes.

First, the method (1) is no longer used because of the cost of managing a large amount of data stored in the regional medical record sharing server and the possibility of serious damage if personal information leaks. ing. Although the method (2) is becoming the mainstream at present, there are problems in that each medical institution incurs software development costs that adapt disclosure data, server installation and operation costs, and the like. In addition, as shown in FIG. 2, document categories and item structures are all different for each medical institution, so that there is a drawback that the shared document categories are limited to a part.
Consider a case where the present invention is applied to a regional medical record sharing system. Users of other medical institutions, or patients and families seeking medical record disclosure, set up an appropriate access control table and register as a user in the document management server system of multiple facilities of the present invention as shown in FIG. For example, unlike the method (2) above, an expensive medical institution disclosure server is unnecessary, and the document management server system of the present invention directly responds to the user of the reference source. If the access right is set, any document category can be referred to as quickly as the original user of the facility. It is not necessary to develop software in advance to adjust the suitability of data for disclosure, which is required in the method (2). If there is a security concern, a relay server that temporarily holds only the disclosed data may be placed between the document management server system of the present invention and the user.

  As document data recording means, each item in the relational database includes an index key item such as ID, document category, creator, creation date and time, and an address item indicating the position of the text data of the subject of the document recorded in XML or JSON format. I have explained the prepared examples. The same function can be realized by using a key-value store type database that has recently been attracting attention as a cloud type data record. In FIG. 15, the document key is a unique document number automatically assigned by the system when document data is newly recorded in the key-value store database, and uniquely represents the position in the recording table. Is. As with the relational database, (1) ID indicating what the document is related to, (2) Document category indicating which category the document belongs to, (3) Indicates who created the document. The creator, (4) the creation date indicating when the document was created / edited, and at least one item and variable length data corresponding to the item as the main body of the document data It is necessary to keep.

ID indicates the patient / student / project number to which the document belongs.
If a multi-facility document is mixed, a facility code is also required.
In the document category, the type, creator, and creation date of the document to which the document belongs indicate who created this document and when.
In the document main body, the body of the document is recorded as an XML format, a JSON format, or a normal text having no CSV or structure.
In the relational database example, it was necessary to enter a fixed-length address in the cell and record the subject of the document at the address destination.
The present invention can be implemented even if the same configuration is adopted and is included in the scope of the present invention. However, in Google's Bigtable and other examples, the data entering each cell allows variable-length data, so the entire text of the document text is included in the cell. It can be said that the direct recording is a more preferable embodiment.
Of course, it is also possible to divide and record a plurality of cells as required.

  The items from the ID to the creation date are index items, and various indexes called a single key index and a composite key index are created in advance, a condition search is performed to obtain a document key, and a logical position in the table is determined. A physical position is obtained, and a target text data of a document is obtained. Various index items are required depending on the situation. As a minimum index item, (1) what item the document relates to, (2) which category the document belongs to, (3) who Each item of whether it is a created document or (4) a created / edited document is indispensable. Using these items, it is good to prepare an index such as a single property index or a composite index in combination to prepare for the search.

Although the embodiments have been described above, the specific configuration of the present invention is not limited to the above-described embodiments, and design changes and the like within a scope not departing from the gist of the invention are included in the present invention.
In the figure, the document management server has been described as being installed in one medical institution. However, when a cluster is formed by a plurality of units and a single virtual server is configured together, a plurality of medical institution units are provided. In some cases, data centers back up each other to form a so-called “private cloud” as a whole. In some cases, (1) if all server functions for data recording and processing are set up on a public cloud such as Amazon or Google and do not have any hardware resources at hand, (2) There may be a case where only the processing such as reading and editing of document data is performed on a server on the cloud via the web while being secured in the server or server group at hand.
The document management server system of the present invention does not need to occupy one server, and may coexist / share with other systems.
Although the web service is used as the preferred communication format via the Internet, an old communication format such as HL-7 may be used because of compatibility issues.
The document management server system of the present invention has a configuration of software and hardware that can manage data of an additional facility as needed even when data of only one facility is not managed directly at a certain point in time. If included, it is included in the present invention.
Although an example of a medical institution was used as an example, the same discussion can be made in an educational institution or an administrative institution and is included in the present invention. The present invention can be applied to any ID that is not limited to a person such as a patient, a student, or a resident, but can be a group of documents such as a case number.

Is set,
The server has a function of identifying access from a user and performing data processing using document processing means on document data of a document category permitted to be accessed according to the accessing user. It characterized a call.

The document management server system according to claim 2 is characterized in that, in the access authority management means, access permission is set for each item and each document category in accordance with a user.

In this invention, since the said structure is employ | adopted, it has the following effects.
In the document management server system according to the first aspect, the server has document data recording means consisting of a plurality of categories recorded according to a predetermined classification . Since it is constituted by a relational database or a key-value store database integrating a plurality of document categories, it becomes possible to handle a wide variety of document data in a unified manner.
Since document category defining means for collecting predetermined items into a document according to the user's request is set, information required by the user can be extracted from the database and presented.
Since item definition means for defining the document items as database data is set, items corresponding to the document are extracted and presented.
The item definition means defines the items constituting the document and their attributes, and the document category definition means and the item definition means combine to create a single document having an item list.
Since the access authority management means for defining the access range of the user is set, the access from the user is identified, and only permitted document processing is performed according to the access authority of the accessing user.

In the document management server system according to claim 2, since access permission management means is set to determine whether or not access is permitted for each item and each document category according to the user, whether access is permitted or not is determined from the viewpoint of the document category. It can be set in detail not only from the perspective of the project itself.

The XML format can express a complicated data structure such as a nested structure or a repeated structure, and thus is highly versatile. However, it takes time to process, and it is uneconomical for data having a simple structure. In such a case, a structure in which “tag” and “data” are simply placed side by side with “:” in between, as in the JSON format, is often more efficient. Depending on the situation, both may be used properly. In the following, the XML format, which has become more practical, will be taken as an example, and the explanation will proceed. The same can be said for the JSON format.
It should be noted that the present invention can be implemented even in a document data file called CSV format in which values are separated by commas “,” or in which the document contents are written as text without any internal structure. Although included in the present invention, it is difficult to understand what each piece of data means, and it is difficult to create a search index.
In the embodiment, the variable length document content data is collected into one XML or JSON file. However, when the amount is long, it may be divided into a plurality of files and recorded. Further, it may be recorded as a plurality of variable length data for each content, such as document content data and document format.
Further, the present invention is not limited to the XML or JSON format, and any document data recorded as variable length text is included in the present invention.
