DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments to which the technical concept of the above-mentioned solving means is applied will be described below with reference to the drawings. FIG. 1 is a functional configuration diagram of the routine business client control system of the present invention. The routine business client control system 1 is connected to a server 2 via a communication line, and the server 2 constitutes a wide area network for centrally managing data. Its internal configuration includes a device group 3 for data exchange, input / output, etc., and these device groups 3
And a client control unit 4 that controls the entire system.

The device group 3 includes a keyboard and a mouse for input, a display device 3a for displaying a screen by a CRT, an LCD, and the like, and various printers 3b for sheet output of a form and the like and bar code output. And the cache storage 3c for assisting data exchange, and other appropriate devices as necessary.

[0010] The client control unit 4 includes a data exchange unit 5 for supervising a data exchange process of a processing request and a processing response with the server 2, a display device 3a, and a printer 3b.
, Etc., and a display processing unit related to input / output which handles intermediate data therefor.

The data exchange unit 5 includes a communication control unit 5a,
It comprises a request processing unit 5b, a cache control unit 5c, and the like. The communication control unit 5a controls network communication with the server 2. The request processing unit 5b exchanges a processing request and a processing response with the server 2 via the communication control unit 5a. At this time, a processing response is preferentially obtained from the cache storage 3c according to the content of the processing request. The cache control unit 5c performs a cache process on a processing response to be covered by the cache storage 3c.

In order to improve the cache efficiency, the processing response is separately handled as an input / output definition command and a data definition command. The input / output definition command defines a routine process according to the input / output mode, and the data definition command defines target data to be centrally managed by the server and subjected to input / output processing. In addition, the request processing unit 5b generates a registration request command for requesting registration of the target data in accordance with the job specification and sends it to the server in order to register the updated target data in the server and centrally manage the target data in the server. .

The display processing unit except for the data exchange unit 5 comprises an execution control unit 6 and a general-purpose function-based processor group or the like which the execution control unit 6 handles. The execution control unit 6 sends and receives a processing request and a processing response to and from the data exchanging unit 5 according to the job content, and supervises a function-specific processor group according to the job content. The processor group for each function is controlled by the execution control unit 6 and is in charge of various display processing for input / output processing.

The function-specific processor group includes a data structure management unit 11 for generating display control data for defining an input / output mode based on an input / output definition command and a data definition command. A dependency management unit 12 that manages a dependency between items of target data based on the
A target data calculation unit 13 that calculates each item of the target data according to the dependency, and an input / output management unit 14 that manages the operation of input / output devices such as the display device 3a and the printer 3b based on the display control data. . Each of them constitutes a general-purpose data processor that performs a process according to a command.

The data structure management unit 11 includes display control data for defining various display modes for input and output corresponding to various display formats such as tables and graphs and display formats such as display screens and sheet printing. And a target data management unit 15, a display element management unit 16, and the like.

The target data management unit 15 mainly generates constituent items of the target data based on the input / output definition command, and sets the actual data in the constituent items of the target data based on the data definition command to define the contents. Along with
Shared management is performed so that reference updating can be performed in data item units required for display control. Based on the input / output definition command, the display element management unit 16 forms various input / output style elements, which are constituent elements of the input / output style, target data, and the like, and a component object that constitutes a data item element, and performs display for input / output. Generate the display components of the control and share and manage them so that they can be referenced in element units.

The target data is mainly defined by a data definition command generated based on a business database registered in the server, and forms a data group of a predetermined format determined by business logic according to a job. Since various display modes can be defined by combining the target data and the display components, various display modes can be defined in a multiplexed manner with the common target data.

For example, by defining various display modes according to a display format such as an input table or a graph for evaluation and a media type such as a display screen or printing, various types of data input operation and update data are defined. In the display according to the aspect, the processing can be completed on the client side without requiring the support of the server. The updated target data is subjected to a data registration processing request for server registration.

The dependency management unit 12 generates a dependency correspondence table consisting of components of an operation formula between items of the target data based on the item operation definition in the input / output definition command, and generates the dependency correspondence table between the items. It has a sort function to sort in the order of dependencies. The data operation unit performs an operation based on the operation expression rearranged by this sorting function,
Data transfer and other target data items that depend on other data items are supplemented. This is displayed by the input / output management unit 14. The same applies to data update.

Next, the data structure of the display control data will be described. The display control data is composed of a combination of display elements, target data and their combinations, and defines various display modes by defining the contents of the configuration via a node serving as a pointer for representing the mutual coupling relationship. I do.

FIG. 2 is an explanatory diagram showing an example of the data structure of display control data handled by the data structure management unit.
A node is a pointer for representing a connection relationship between items. Each node has upper U, lower L, leading P, and trailing N pointers, and in the case of a data node, a data pointer D pointing to entity data, and the entity data is accompanied by a reference count, a change count, and the like.

In the illustrated example, a configuration in which item B is transcribed and used for item D is shown. By overloading to set the data pointer of item B to the data pointer of item D, a change in one entity data is always reflected in the other.
Further, according to the operation definition representing the calculation formula between the items, the items X and Y are combined with the group A including the items B, C, and D by pointers indicating the leading P and the trailing N, and are extracted by the binding relationship. The calculation is performed using the entity data, and the calculation result is stored in the data pointer position pointed to by the items X and Y, which can be shared by all the reference sources by referring to the other display elements. Becomes

Therefore, the common part of the display style and the target data can be handled in common by the instruction of the pointer, so that the result can be reflected in all display modes especially when the target data is updated.

A table handled by the data structure management unit;
Various display formats such as graphs share the target data within the scope of one business process, and display screens,
Even if there is a difference in the display form such as sheet printing, the display style is often made common, so that the display control data defines its content by a hierarchical structure that can be combined in any number of stages via nodes. This can eliminate disturbance of mutual cooperation due to individual handling.

FIG. 3 is an explanatory diagram showing the contents of the intermediate data accompanying the processing at the time of data change. The dependency correspondence table in FIG. 7A is a table in which the items to which the operation items defined by the operation definition are dependent, that is, the element items constituting the operation expression of each operation item are arranged. The arithmetic expression is set in advance in a table cell forming each data item of the target data.

When the item D, which is a dependent item of the item C defined by the arithmetic expression, is changed, the item that receives the change is picked up according to the dependency correspondence table, and the item that receives the change is shown in FIG. Register on the dependency list. That is, the variable item C having the change item D as the dependent destination is picked up by searching for the dependent destination in the dependency relationship table. Next, the items which are changed by the picked-up item C are picked up and registered in the dependency list in the same manner as described above, and by repeating this, all the changed items are picked up as the dependency list (D) relating to the item D.

When the dependency list (D) is created, the dependency list (D) is rearranged according to the dependencies of the dependency correspondence table, and the duplicate items are arranged and registered in the sort list of FIG. By calculating the operation formulas in the order of this sort list, it is possible to efficiently reflect the change result by eliminating useless calculations in the related parties that cause the fluctuation.

The overall operation of the routine business client control system having the above-described functional configuration will be described. FIG. 4 is a processing procedure diagram showing an input / output definition command. A processing request corresponding to the designated job selected from the system menu is sent from the display processing unit to the data exchange unit including the communication and the cache. This processing request can be satisfied by the cache by individually requesting the input / output definition command and the data definition command. The burden can be reduced and the load can be distributed.

If the input / output definition command is not in the cache, a processing request is made to receive the input / output definition command from the server (step 1). The client receives the corresponding processing response and registers it in the cache (step 2). If the input / output definition command is in the cache, the input / output definition command is received from the cache, and the input / output definition command is expanded by the execution control unit into a dependency correspondence table, target data, display components, and the like (step 3). . Based on these display components and the target data, display control data of various forms such as a display form of a table or a graph and a display screen or a print display form is generated based on an input / output definition command.

FIG. 5 is a processing procedure diagram showing a data definition command. After the completion of the processing for the input / output definition command, a processing request is made to receive a data definition command from the server (step 1). The data is extracted from the business database by the business processing logic corresponding to the job content, a data definition command is generated to define the target data as an input / output target, and sent to the client as a processing response (step 2). The contents are set in the target data by the received data definition command, and the preparation of the display control data for input / output is completed (step 3).

Here, when data is input through the display and the keyboard, the target data changed by the dependency processing can be reflected in various outputs. Further, in response to the output instruction, the evaluation graph based on the revised data and the management data in the form of a table are displayed on the display, and a printed output can be obtained (step 4). These outputs can be efficiently processed by internal processing on the client side without the assistance of the server.

FIG. 6 is a graph showing the operation speed of the response process in relation to the number of repetitions. In the case of the WWW system A, even if the same business process is repeated, the response is determined by the communication speed with the server, so there is no significant change. In the case of using the dedicated system B installed in the client, excellent response is obtained. Can be obtained.
On the other hand, when the present system C is used, the first time is affected by the communication speed, but since the second time, the communication amount is suppressed, so that excellent responsiveness similar to that of the dedicated system B can be obtained. . Further, since the present system handles the display style and the data structure separately as described above, it is easy to cope with the use form and the display capability of the terminal, so that not only the above-mentioned responsiveness but also the production in the system adjustment can be achieved. It also has the possibility of improving the performance.

[0033]

The routine business client control system of the present invention has the following effects. The above-mentioned routine business client control system is configured so that the processing response from the server can be cached by dividing the processing response into an input / output definition command and a data definition command. Since the input / output definition command can be obtained from the cache, communication with the server can be minimized, and the responsiveness of routine business processing can be ensured even under a low-speed line.

Further, the target data management unit manages the target data for each item based on the data definition command, and the input / output management unit performs input / output processing on the target data according to the input / output definition command. Input / output can be defined for various display modes described above, so that input / output processing in various modes can be internally processed on the client side. Therefore, the above-mentioned routine business client control system uses a general-purpose input / output management unit and a target data management unit to secure the input / output responsiveness without requiring a high-speed line and to reduce the individual maintenance load on the client side. It is possible to cope with various types of input / output display processing without necessity.
