It is. In addition, the present invention relates to a form data storage management method when form data is divided and stored in a form data storage management system, and a form data storage management method when processing for searching each data of the divided and stored form data is performed in a distributed manner. is there.

[0002]

2. Description of the Related Art In recent years, computerization of business has rapidly spread due to a trend toward lower prices and cost reduction of computers.
Some of these various electronic systems are
2. Description of the Related Art There is a computer system that stores and manages a form output from a mainframe of a computer system in the form of electronic data, and can perform reference and search in a computer system of a workstation having an electronic display device.

As a reference and search method in such a computer system, form data is stored in an external storage device such as a hard disk device or an optical disk device (for example, a CD-R) of the computer, and is referred to using an application dedicated to the data. Methods are known.

[0004] Such a computer system can be classified into a client-server type system and a data distribution type system depending on a combination of a method of storing and referring to form data, depending on a form in which the system is constructed.

[0005] The client-server type system is composed of one server that receives data from an output source of form data and performs search processing and the like from storage management of all data, and a plurality of clients that display and search forms. You. Each client acquires the form list information stored from the server, selects a form to be referenced from the information, and sends a data acquisition request to the server. Upon receiving the request, the server sends a copy of the stored form data to the requesting client. Similarly, during display of the form, the server performs the search process by setting the search process and sending it to the server.

On the other hand, a data distribution type system is a system in which a computer which receives data from a form data output source distributes the form data to a preset base. As a delivery method, there are an online method in which data is transmitted via a communication line, and an offline method in which data until a certain data amount or time is reached is stored in a transportable storage medium such as a CD-R and physically transmitted. Exists. At the site which receives the form data in any of the methods, the form reference / search processing is performed by an application prepared in advance.

There is also a system in which a client-server type system and a data distribution type system are integrated.

[0008]

In the case of a client-server system, when the number of clients increases, the processing is concentrated on the server, the load on the server increases, and the response of the request processing of each client decreases. In order to solve such a problem, a conventional system generally introduces a plurality of servers to reduce the number of clients per server. At this time, since the introduced server acquires the form data, the entire form data stored in the conventional server is duplicated, or the external storage device of the existing server itself, or only the form data portion is shared. There is a problem that complicated work occurs.

Further, in the case of the data distribution type system, since the same form data is sent to each site in common, there is a possibility that form data that is not used may be sent. Consume. Conversely, when it becomes necessary to refer to form data that is not distributed, a procedure for distributing the target form data is required. As described above, there is a problem that unnecessary data and necessary data cannot be flexibly handled.

[0010] It is an object of the present invention to transfer form data to a plurality of sites (servers in a client-server type system,

The processing function provided by the central server group 1 divides a large amount of form data stored in the system based on a data type for using the form data, and divides the divided form data into a processing server group at a storage destination. This is a function for managing the form data distributed and distributed to the processing server group by the form data management information. The processing functions provided by the plurality of processing server groups 9 include the central server group 1
Is a function of saving the distributed form data, performing a search process on the stored form data, and issuing a search request and a reference request for the form data stored in the system to the central server group 1.

As will be described later, the central server group 1 determines whether or not there is a common part among a plurality of form data as a data type for using the form data. The form data is divided according to three kinds of characteristics, that is, whether or not the part is frequently referred to.

The central server group 1 includes a data division / distribution server 2, a usage information database 3, a storage management processing server 4, a request reception server 5, a storage management information database 6, a network correlation table 7, The processing server group 9 includes a distribution determination server 8, and the plurality of processing server groups 9 includes a form data storage unit 11 that stores form data, a request processing server 10, and an actual processing server 12.

In the central server group 1, the data division distribution server 2 divides the form data to be stored and distributes the divided form data to the processing server group 9 for storing the divided form data. The usage information database 3 stores past operation status information obtained by evaluating the operation status of reference to form data, and the storage management processing server 4 stores temporary data based on the information in the usage information database 3. Or decide to discard,
A discard command is transmitted to the processing server group 9. The request receiving server 5 receives various requests from the processing server group. The storage management information database 6 is a storage destination server identification information for identifying a processing server group as a storage destination of the form data, a data identification information for identifying a type of the stored form data, and a state instructing a storage state of the form data. The storage management information is accumulated from the information and the network correlation table 7
Records the evaluation points of the communication capability by evaluating the communication capacity of the communication network between the respective server groups, the distance between them, the communication cost, and the like. The processing distribution determination server 8 includes the request reception server 5
With reference to the network correlation table 7, the processing request received by the server is appropriately distributed and transmitted to the processing server group 9.

In the processing server group 9, the form data storage unit 11 stores the form data 11 a distributed from the central server group, and the request processing server 10 transmits the search request sent from the central server group 1. Upon receiving the data transmission request, the actual processing server 12 performs a search process on the form data stored in the form data storage unit 11 and distributes the form data to the request source that issued the data transmission request.

That is, the central server group 1 having a central processing function for performing the storage management of the form data and the control processing of the processing distribution is provided as a system by a plurality of server groups, and the central server group 1 is provided with the function. A data division / distribution server 2 that divides and distributes form data, and a usage state information database 3 that inputs the operation state of form data from each computer and stores past operation state information
The storage management processing server 4 determines whether to save or discard the temporary data based on the request, transmits a discard command, the request receiving server 5 that receives various requests from each computer, and stores the received request in the storage management information database 6 or Network correlation table 7 summarizing the line status of the communication network connecting each server group
And a processing distribution determination server 8 that distributes processing request destinations and transmits the processing request destinations.

The processing server group 9 receives the processing request from the central server group 1 and stores the divided form data, searches for the stored form data, and searches for the form stored in the system. -Issue a reference request. The processing server group 9 also provides its function by a plurality of server groups. Request processing server 10 of the processing server group 9
Issues a reference / search request based on the form information distributed from the central server group 1, and accepts a search request and a data transmission request sent from the central server group 1. In the accepted process, the actual processing server 12 performs a search process based on the stored divided form data 11. The communication network 13 connecting the central server group and each processing server group is a public telephone line, LA
An N communication network or the like is used, and is a communication network connecting the central server group to each processing server group and between the processing server groups.

The processing server group 9 corresponds to a base of a conventional electronic form system, and a client may be further connected to this server group. When configuring a server group, both a configuration using a plurality of computers and a configuration using a single computer are possible. In a system with a large number of connected clients or a huge system with a very large amount of data to be handled, in the case of the central server group 1, a computer is assigned to each server function and the processing load of each processing is distributed within the central server group. By doing so, the response to the processing server group can be improved as compared with a single computer configuration. Similarly, in the processing server group 9, by assigning a computer to each server function, two large loads of the communication control processing and the form data search processing are distributed, and the response to the search processing and the like from the central server group is further increased. It is possible to improve.

On the other hand, in a system in which the number of clients connected to each processing server group is small, when a system is constructed for data sharing, it can be dealt with by configuring each server group with a single computer. . Thus, when actually configuring the system, various computer configurations are possible according to the scale and purpose of the system.

FIG. 2 is a view for explaining data types according to the characteristics of the form data for using the form data.
In the form data storage management system according to the present embodiment, form data is divided to be distributed and stored in the processing server group. As a basis for division, data to be stored in the system is divided into a plurality of data types by the data type described here. The form data is classified based on three types of characteristics, namely, whether there is a common part in the form data, whether the part is used in search processing, and whether the part is frequently referred to.

As shown in FIG. 2, the data constituting the form data is first classified into a large type and a type A and a type B as shown in FIG. Classify into. Type A is data unique to each form data and cannot be shared between different form data. Type B is data that can be reused between forms having a common attribute.

In the type A, data that can be subjected to a search process is defined as A-1 type data, out of the form data in which there are relatively many opportunities to be referred to in daily work. The A-1 type data type is data such as numerical value, date, and character string data described in an accounting book, a sales record, and the like, and is data of an actual data portion of a form. On the other hand, data that cannot be subjected to a search process, such as image data attached to a form, a ruled line, or a graph based on a graphic, is defined as A-2 type data. However, format data is not included.

Then, other types of data that do not correspond to the A-1 type data and the A-2 type data, that is, ordinary data such as job logs on the mainframe and copy data at the time of issuing a large number of specifications. Data that is not referred to in business, but needs to be referred to for unexpected reasons, such as analysis at the time of abnormal termination of a job or reissue of a statement, is defined as A-3 type data. The A-3 type data is data that is often not stored but only stored.

As data to be classified into type B, data carrying the same display between forms having common attributes, such as form data of form data, is defined as B-1 type data. In addition, data indicating form attributes such as display contents and item names of the form, and configuration information are defined as B-2 type data. Thus, the data type is defined according to the classification criteria for using the form data. The table shown in FIG. 2 also shows the data characteristics of the form data of each data type. In other words, the possibility of sharing between different forms, the possibility of executing search of each data, and the characteristics (high or low) of the reference frequency are also shown.

More specifically, FIG. 13 and FIG. 14 show an example in which the data of each part of the form data is classified according to the classification criteria of each data type. FIG.
It is a figure showing the example of A-3 type data of the form data.
For example, a large amount of data output as a form for storage purposes. The log data 21 of a large computer corresponds to this. The log data 21 of such a large computer is data that has been conventionally recorded as a sequential data 22 on a magnetic tape or the like.

FIG. 14 shows A-1 type data of the form data,
FIG. 4 is a diagram showing specific examples of A-2 type data, B-1 type data, and B-2 type data. As shown in FIG. 14, for example, when the data 23 of the order result list for each settlement period / branch is classified according to the data type, the format data 24 of the form data is
Ancillary data 25 such as image data, ruled lines, and graphic graphs attached to the form correspond to A-2 type data. Further, data 26 indicating form attributes such as display contents and item names of the form, and configuration information correspond to the B-2 type data. The actual data portion 27 of the form data most frequently used in search processing and reference processing that occurs in daily work and is frequently referred to corresponds to A-1 type data.

Next, each processing content in the form data storage management system here, that is, a series of processing based on each server processing function provided by the server group of the central server group 1 and the processing server group 9 This will be described with reference to some flowcharts.

First, the flow of processing until form data is input to the system and stored will be described. For explanation of the flow of this processing, reference is made to FIGS. 3, 4 and 5. FIG. 3 is a flowchart showing processing in the data division / distribution server 2 of processing until form data is input and stored. FIG. 4A is a diagram illustrating data stored in the storage management information database 6, and FIG. 4B is a diagram illustrating form registration information stored in the divided data storage unit 11 of the processing server group 9. FIG. 4C is a diagram illustrating a data structure of the divided data of the form data stored in the divided data storage unit 11 of the processing server group 9. FIG. 5 is a flowchart showing the processing in the processing server group from the processing until the form data is input and stored.

Processing until the form data is input and stored in the system is mainly processing by the data division / distribution server 2 in the central server group 1. The form data divided by this processing is distributed and stored. Is distributed to the processing server group 9 and stored there.

First, reference is made to FIG. When the form data to be stored is input to the system, the central server group 1
Is sent to the data division distribution server 2 (step S301). The input data is shown in FIG.
As shown in (1), a basic analysis process for data division is performed as an initial analysis based on the form characteristics 61 set in the storage management information database 6 (processing step S30).
2).

The result of the basic analysis processing is determined, and it is next checked whether or not there is B-1 type data in the input form data (processing step S303). B-1
If the type data exists, it is checked whether the data is already stored in the system (processing step S3).
04) If it already exists in the system, B-1 type data is not included in the storage target (processing step S3).
06), remove from the current save target. If it does not exist in the system, the B-1 type data is included in the storage target (processing step S305). After the check in the processing step S303, the form data is classified for each type and the first division processing is performed (processing step S307). After the form data is divided, data type processing in processing steps S320 to S327 is performed for each data.

In the processing for each data type in the processing steps S320 to S327, first, the data type is determined (processing step S320). In the case of A-1 type data and A-2 type data, processing step S321
, The form data is divided into processing units. That is,
Perform subdivision of data. At this time, the division unit is a unit where data continuity is broken, such as a page unit or a unit for each destination. The divided data is processed in processing step S
In step 322, two distribution destinations are determined with reference to the data in the storage management information database 6 while considering that the data is not biased in the system, and each part is distributed to two locations (processing server group). The process of distributing the divided data to two places not only realizes the security of the data, but also aims to efficiently distribute the data because the A-1 type data and the A-2 type data are frequently referred data. is there. After the distribution destinations are determined, they are distributed to the respective distribution destinations via the communication network 13.

The data type is determined (processing step S3
20), for A-3 type data, processing step S32
In 3, the form data is divided into processing units. Similar to the processing step S321, the data is re-divided, but the division unit is a division size registered in advance. After the completion of the re-division or during the division, data for restoring the divided data is created (processing step S324). This data for restoration of divided data is for restoring the lost divided data by executing a restoration process in combination with other remaining data when certain divided data is lost or damaged for some reason. The restored data is created using the result of exclusive OR of two different divided data. Then, in processing step S325, each part and data are distributed to the processing server group of the storage destination. In the data distribution process, after the division of the form data and the creation of the data for restoration are completed, the storage management information database 6 is referred to and the amount of stored data is small considering the balance of the data amount among the processing server groups. The destination is determined from the processing server group.

The data type is determined (processing step S3
20), for B-1 type data, processing step S32
In 6, the attribute information of the form that can use the data,
It is stored in the storage management information database 6 as the form characteristic 61 and is associated. After registering this save and association,
As with other data, the destination of the data is determined with reference to the storage management information database 6 and distributed (processing step S3).
12).

After the distribution of each data according to each data type is completed, the distribution result is registered in the storage management information database 6 (processing step S30).
8). As shown in FIG. 4A, the storage management information record 62 registered in the storage management information database 6 includes the following data. That is, the field data includes an identification ID 621 for identifying a processing server group of a storage destination, data identification information 622 indicating what data is stored, and a state 623 indicating a data state. The content saved as the state 623 is that the data distributed here is master data in the system.
"M" indicating master data is set.

Processing steps S322, S325, S32
As shown in FIG. 5, the data distributed by the request processing server 7 in the request processing server 1 in the processing server group 9 to which the data is distributed is transmitted.
0 and the actual processing server 12 perform the reception processing and the data storage processing (processing steps S310, S31
1). The divided data 11a of the received data is stored in the divided data storage unit 11, which is an external storage device of the processing server group 9.

As shown in FIG. 4C, the divided data 11a includes data identification information 111 indicating what data is stored, a state 112 indicating the state of the data,
Then, it is composed of each field data of the actual data 113. The data stored as the state 112 is set with “M” indicating that the data is master data, similarly to the storage management information record 62 stored in the storage management information database 6.

Referring back to FIG. 3, when all the divided data are stored in the system, the data division distribution server 2 notifies all the processing server groups 9 that a new form has been registered. The form registration information to be transmitted is transmitted (processing step S309). In all the processing server groups 9, as shown in FIG. 5, the request processing server 10 and the actual processing server 12 receive the notification of the form registration information, and store the form registration information 91 in the divided data storage unit 11 of the external storage device. register. As shown in FIG. 4B, the form registration information 91 includes information 911 for identifying a form, a list of B-1 type data related to the form, and related information 912 of B-2 type data. Is done.

Next, the flow of processing in the system when a form data display (acquisition) processing or a search processing is performed in a certain processing server group will be described. Here, FIG. 6 and FIG. 7 are referred to for explanation of such a processing flow. FIG. 6 is a flowchart showing the flow of processing in the processing server group and the central server group of the processing request source when performing the form data display (acquisition) processing or search processing. FIG. 7 is a flowchart showing the form data display (acquisition) processing or search. 10 is a flowchart illustrating a processing flow of a processing server group that performs processing by distributing a processing request from a central server group when performing processing.

Referring to FIG. 6, a processing request is transmitted from the processing server group 9a of the processing request source to the request receiving server 5 of the central server group 1. That is, the process is started, and in step S401, the contents of the form data acquisition or search request generated from the processing server group 9a are transmitted to the central server group 1. Since such a request content is issued after searching the form registration information 91 in the own server group 9a in advance for a form having target data in the request processing server 10, the processing request is received. The central server group 1 may simply execute the received contents as it is,
This prevents concentration of processing on the central server group 1.

The request contents sent from the processing server group 9a are analyzed by the request receiving server 5 of the central server group 1 (processing step 402), and the request contents are sent to the processing distribution determination server 8. The processing distribution determination server 8 acquires the storage destination of the target data from the storage management information database 6 and
Decide where to distribute the processing. That is, the transfer source (search execution destination) is determined based on the storage management information and the network correlation table. When there are a plurality of candidates, the nearest processing server group is selected from the network correlation table (processing step S40).
3).

When the distribution for performing the processing distribution is determined,
The “transfer source (or search execution destination) list” is transmitted to the processing server group 9a as the processing request source (processing step S40).
4) A data transfer command (or search execution command) is transmitted to each processing server group 9b that executes the process (processing step S405).

As shown in FIG. 7, in the processing server group 9b executing the requested processing, the processing request transmitted from the central server group 1 is transmitted to the request processing server 10 of the destination processing server group 9b. Received (processing step S40)
6), the request is analyzed (branch step S4)
07). If the result of the analysis of the request content is “data transmission”, a copy of the requested divided data is transmitted to the request source (processing step S408). On the other hand, if the result of the analysis of the request content is “search processing”, the request content is passed to the real processing server 12, the search processing is performed in accordance with the request in the real processing server 12 (processing step S 409), and the search result is requested. The original is transmitted (processing step S410).

As shown in FIG. 6, in the processing server group 9a that is the processing request source, after transmitting the processing request, it waits for distribution of the requested processing result. In this case, the “transfer source (or search execution destination) list” 9 transmitted from the central server group 1 9
3 (processing step S411), and then the processing server group 9a waits until all data is sent from the processing server group on the list (processing step S412, branching step S413). If the processing request is a form data acquisition request, the divided data 1 is temporarily stored in the external storage device at the time of completion.
1a is registered (processing step S414). The field data portion of the record state 112 of the registered divided data 11a is set to "B" which means temporary data. From that point, a periodic check of the number of data references is started (processing step S41).
5). On the other hand, in the case of a search request, processing such as display of search results is performed when the data is completed (processing step S414).

Next, the flow of processing relating to continuation or discard of temporarily collected form data will be described. 8, 9 and 10 will be referred to for explanation of the flow of this processing. FIG. 8 is a flowchart for explaining the processing flow in the processing server group for the processing relating to the continuation or discarding of the form data, and FIG. 9 is the flowchart of the processing in the central server group for the processing relating to the continuation or discarding of the form data. It is a flowchart explaining. Also,
FIG. 10D is a diagram illustrating data stored in the storage management information database 6, and FIG. 10E is a diagram illustrating a data structure of usage status information stored in the usage status database 3. It is.

Referring to FIG. The processing server group 9 monitors the usage status of the temporarily stored divided data 11a (processing step S501), and the divided data 11a temporarily stored in the external storage device in the processing server group 9 is monitored.
Is checked how many times it has been used after registration when it reaches a certain time (branch step S502). At this time, if the prescribed number of times has not been satisfied, it is determined that the role of temporary storage has been completed, and the divided data 11a is deleted (processing step S503). If the number of times exceeds a prescribed number, the data is considered to be highly used in the processing server group 9 and very useful for storing and operating in the own server group, and the state of the divided data 11a is changed from a temporary state to a temporary state. In order to take the procedure of elevating to "temporary registration", "temporary registration application" is transmitted in the own server group of the relevant data (processing step S504).

By performing the temporary registration procedure, the data can be kept in the own server group for a longer period than the check period at the time of temporary storage, similarly to the master data. Eliminates the need to collect data. Therefore, the time for acquiring and displaying the form data can be reduced, and the load on the network and the central server group can be reduced.

In order to give priority to the processing distribution in the search processing, a processing request is issued to the central server group 1 in the same manner as in the prior art. However, at that time, the own server group becomes a target of search processing distribution. Similarly, it plays a part in transmission when a data acquisition request is made in another processing server group.

After the "temporary registration application" is made to the central server group 1, the field data of the state 112 of the divided data 11a is updated to "R" indicating that the data is temporary registration data (processing step S505). Then, in addition to the number-of-uses check that has been performed since the time of the temporary storage from that time, the frequency of the data transmission or search processing request from the central server group 1 is also included in the aggregation item and the check is restarted (processing step S506). .

Referring to FIG. 9, the provisional registration application from the processing server group 9 is received by the request receiving server 5 of the central server group 1 (processing step S507). Pass the request contents. Upon receiving the request, the storage management processing server 4 adds the storage management information record 62 to the storage management information database 6 in the same manner as when the master data is registered (processing step S508). The state 623 of the record is set to “R” as in the process 504. Next, in processing step S509, a record 31 of the usage status information for storing information used for determining the continuation of the storage described later is added to the usage status information database 3.

As shown in FIG. 10, the record 31 of the usage status information includes a processing server group identification I indicating a storage destination of data.
It has a data structure of D311, an identifier 312 for identifying data, a current evaluation point 313 indicating an effect as a current provisional registration, and a past use status information 314. In the initial state, 0 other than the identifier is set, and the next “evaluation of the effect of the temporary registration state” (processing step S51)
3) Set the data thereafter.

After a certain period of time after the temporary registration, the processing server group 9 transmits to the central server group 1 a “usage status report” that summarizes the usage status of the temporarily registered data (processing step 510). The transmitted report is sent to the storage management processing server 4 via the request receiving server 5 of the central server group 1.
(Step S511). After receiving the report at the storage management server 4 (processing step S512),
A process of determining whether there is an effect of continuing the storage as the temporary registration is performed, a process of reevaluating the storage effect in the temporary registration state is performed (processing step S513), and the effect as the temporary registration is reevaluated. The details of the reevaluation will be described later with reference to FIG.

After the re-evaluation, the evaluation points (results of the re-evaluation expressed concretely in numerical values) are determined (branch step S
514). If the evaluation score is one or more, it is considered that there is an effect of continuously storing the temporary registration, and the evaluation score and the contents of the current usage status report are reflected in the record 31 in the usage status information database 3 (processing Step S
515). When the score is lost in the re-evaluation, it is considered that there is no effect as the temporary registration, and the corresponding record in the storage management information database and the usage status information database is deleted (processing step S516). A "temporary registration cancel instruction" is transmitted (processing step S517).

FIG. 8 is referred to again. The processing server group 9 receives the “temporary registration cancellation instruction” (processing step S
518), the processing server group 9 updates the “status” portion of the corresponding data to “B” indicating temporary storage (processing step S519). Thereafter, the divided data 11a returns to a state (processing step S501) in which only the usage status is checked again as the temporarily stored data.

FIG. 11 is a flowchart showing the re-evaluation processing of the storage effect in the temporary registration state in the processing step S513 of FIG. 9. FIG. 12 shows the evaluation method used in the re-evaluation processing of the storage effect in the temporary registration state. Is shown as an example of the calculation reference.

In the re-evaluation processing of the storage effect in the temporarily registered state, the previous evaluation point of the data to be re-evaluated and the data of the past usage status are acquired from the usage status information database 3 (processing step S601). . An evaluation point common to all data is calculated based on the acquired data (processing step S602). Then, the data type is determined, and each process is performed according to the A-1 type data or the B-1 type data. In this process, in the case of A-1 type and B-1 type data, a unique evaluation point that further utilizes the characteristics of the data is calculated (processing steps S603, S604, S60).
5). Here, in the processing step S602, the direct reference evaluation point calculated is a point indicating the degree of contribution to the reduction of the traffic amount obtained by preventing the temporary registration data from collecting data via the communication network. .

As a calculation method, as shown in FIG. 12, evaluation is performed based on each calculation standard. For example, a method (71) of estimating the number of times of reference this time from the number of times of reference in the past and converting the difference between the estimated value and the actually measured value into a point (71) or a method of evaluating the number of times of reference of the temporarily registered data by a deviation value (7
2) is used. In any case, a point with a high reference frequency is given a plus point, and a point with a low reference frequency is given a minus point.

Next, as a calculation criterion for calculating an evaluation point for each data type, in the case of the data type of A-1 type data, in addition to the reference in the own server group, data acquisition from another processing server group or There is a request for search processing. Based on this, the point at which the degree of contribution to the processing distribution and data distribution from the viewpoint of the system is pointed is the “processing distribution evaluation point”. As an example of the conversion of the evaluation points into points, a method (73) in which the points are pointed by the ratio of the number of times the target temporary registration data is used to the entire request processing is used.

In the case of the data type of the B-1 type data, even if the original target form data itself becomes unnecessary, the data can be reused when referring to the form output periodically. . Therefore, when a form associated with the B-1 type data is periodically output, a correction point is calculated so that an evaluation corresponding to long-term storage can be performed according to the output period (74).

Finally, the sum of each evaluation point calculated this time and the current evaluation point is set as a new evaluation point (processing step S606). However, when a new evaluation point divides 0 point by this calculation, it is set to 0 point. Based on the evaluation points calculated here, branch step S in the processing flow of FIG.
At 514, continuation or cancellation of temporary registration is determined.

[0073]

As described above, according to the form data storage management system of the present invention, the form data that has been duplicated among a plurality of sites is shared, thereby saving the form data as a whole. Data amount can be reduced. At this time, instead of simply reducing the data, the data is stored in a data arrangement that has the best balance between the data amount and the operation status at each site. Therefore, the data can be stored efficiently in the system. At the same time, data security can be obtained by decentralizing the data. Furthermore, since the central server group collectively manages information relating to the storage management of the form data, efficient processing distribution is realized,
Response such as form reference is improved. Data that is more rooted in actual use of form data by evaluating the storage effect according to each data type rather than making a uniform decision to save and destroy data other than master data Can manage.

Conventionally, when a site (server group) is added, complicated work related to duplication and sharing of an external storage device for storing report data has occurred. By simply adding a processing server group to the central server group, the sharing of form data and the processing distribution are performed automatically, so that it is possible to flexibly cope with system expansion.
