Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rounding control method that links data between applications when a plurality of consecutive screen processing applications perform common information processing.

Generally, when a data processing request is made from a terminal device to a central processing unit, it is often necessary to process screens several times in an interactive manner, and it is necessary to link data between the screen processes. The present invention relates to a data linkage control system configured to perform data linkage via a scratchpad area in such a case.

First, the technical background of the present invention will be explained.

FIG. 1 is an explanatory diagram showing the relationship between application processing and the scratch pad area SPA in the conventional method. In the figure, 1.2.3 indicates consecutive screen units 1. in any one job for which a processing request has been made from the terminal.
Indicates n and m. It is assumed that each screen has a hierarchical structure in which other processing is superimposed on the result of the previous screen processing. 4.5.6 is a business application 1. for processing message input from screens I, ■, and 1[l. Il and III are shown. 7 is a scratchpad area SPA on the storage device for executing application processing, and includes areas 8.9.10 set corresponding to each application. 11 indicates a file storage device.

Application I consists of hierarchical processing that links data A to screen I, common information 1 processing that is common processing for data B across each screen, and common information 2 processing that also relates to data C. There is. A SPA area 8 is set up for each of the above processes regarding application summer. The necessary program modules, data, etc. are loaded here from file 11 and used as a dedicated storage area for application l. Examples of common information processing include table search, logic, arithmetic processing,
When the processing of O application (2), which involves file updating, input/output processing, etc., is completed, the process moves to step H on the first screen, and application (2) is started. Application (2), like application I, consists of hierarchical processing using data A, processing for common information 1 using data B, and processing for common information 3 using data D. Furthermore, application (2) corresponding to the next screen m consists of hierarchical processing using data A and common information 3 processing using data D. These applications ■ and ■ also each set a SPA area 9.10, similar to SPA area 8 in the case of application I.

It is used as a dedicated storage area by loading the programs, modules, and data needed to process the application.

Each SPA area 8, 9.10 is managed by the corresponding application, and when one screen processing is completed,
The management function of that SPA area disappears. Therefore, program modules whose applications are common in subsequent screen processing.

When using data records, etc., even if the same record existed in the SPA area used by the previous application, it could not be used and it was necessary to reload it from the file.

The present invention aims to improve the data linkage problems between SPA areas in the conventional method described above and improve the processing efficiency of the system. It provides:

The present invention provides a data processing system having a screen processing application with a one-layer structure as a configuration for that purpose.
A scratchpad area is set for each different type of common information processing between each application, and this area is commonly managed, and when each subsequent application performs common information processing, the scratchpad area corresponding to the type of common information processing is used. By doing so, data is linked between applications.

The present invention will be described in detail below with reference to Examples.

FIG. 2 is an explanatory diagram of nine embodiments of the present invention. In the figure, 1 screen 1. It, IIl, and Applications 1. Il and Ill are the same as those in the conventional example shown in FIG. However, in the case of this embodiment.

Unlike the example in FIG. 1, the area configuration of 5PA12 is not for each application but for the type of processing. Each application uses a different SPA area for each different type of internal information processing unit. SPA areas (A) to (D) set for each information processing type
shows. The information processing type is defined in units of combinations of program modules and data. Basically,
In order to improve the efficiency of data record input/output processing, it is advantageous to set SPA areas using data that is commonly used by each application as a division unit.

First, application ■ uses the processing program and data A placed in the 8PA area 13 for information processing type (A) when performing 1st layer processing, and uses the common information 1 as the primary
When processing is performed on data B, nine SPA areas (B) are set for the information processing type (B) of common information 1.
14 is used to perform the processing of the common information 2 on the data C as the primary.

Information processing type CC) of common information 2 is set for K and 9S
Use PA area (C) 15. When the processing of Application I is completed, these SPA areas 13-15
The pressure information, including the processing results, will be left as is.

Moving on to the processing of the application (2), the hierarchical processing using the first data A and the processing of the common information l using the next data B are the same as the corresponding processing in the application Summer.

Processing is performed using SPA area (A) and SPA area (B). For processing of common information 3 using the following data D, K is BPA area CD of information processing type CD)
)16 are used. When the processing of application (2) is completed, the information of SPA areas 13 to 16 is left including the processing results.

Next, process the application ■ in the same way.

This can be done only by using the SPA area (A) 13 and the SPA area CD) 16.

In this way, by linking the information of successive screen processing through the SPA area, data management is easily met and data linkage design is facilitated.

21 is an application control unit that manages and controls each application in response to processing requests from the terminal devices 18g and 181, and 21 is an application 1.1. II, an application processing unit that executes the processing.

22 is a scratch pad area SPA of the storage device,
23 indicates the information processing type and the areas (A) and (B) within the SPA.

This is a SPA management table that provides correspondence between (C) and (D). The index to the information within each SPA area (A-CD) is provided by a directory within each area, but may also be summarized in table 23. Note that FIG. 0 specifically illustrates the access operation of application (2).

The application control unit 20 instructs the application processing unit 21 to execute an application in order to process messages from the terminals 186 and 184. The application processing unit 21 requests the application control unit 20 to load the processing program and data into the main storage area.

The application cage activation control unit 20 identifies the information processing type of the requested information, refers to the SPA management table 20, and
If the request information exists in the PA, notify the application processing unit 21 of its address or directory location. If the requested information does not exist in the SPA, a new area is set in the 5PA 22, its address is registered in the SPA management table 23 along with the information processing type, and the pressure information requested from the file storage device 19 is loaded. and notifies the application processing unit of the SPA area address. The application processing unit 21 performs conventional address conversion processing to make the addresses on each application program SPA transparent.

The present invention has been described above based on embodiments.

According to the present invention, programs and data related to each application are divided according to standard types, and the scratchpad area is commonly managed according to the type, thereby linking data between consecutive applications via SPA. The details of its implementation can be modified in many ways by applying common design techniques in the field.
