Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a system for controlling office batch processing based on the validity (existence) or invalidity (absence) of data.

(2) Prior art and problems Conventional matter [The execution control method for data processing in batch processing is defined by one program counter, and the processing algorithm must be programmed in one control flow. However, when performing multiple processes, the processing logic becomes complicated.

(3) Purpose of the Invention The present invention solves the above-mentioned drawbacks, and easily and efficiently controls the execution order of data processing using a data driver (execution control only when all the data necessary to execute the processing is prepared). By using the language processing system to control the data processing, it is possible to eliminate the need for programming complex logic to control the execution order of data processing (improving software productivity) and to process multiple processes in parallel. The purpose is to provide a method that allows

(4) Structure of the Invention The purpose of the invention is to execute a process when input data of a certain process becomes valid and output data becomes invalid in a system in which multiple processes execute processes while passing data. (9) A data processing method characterized in that a means for controlling execution of a plurality of processes in a desired order is provided.

(5) Examples of the Invention The present invention will be described in detail below with reference to the drawings. The figure is an overall block diagram showing one embodiment of the present invention.

In the figure, 11 is file A112 is file B11
3 is a process A 114, a process B 115 is a main memory, 16 is a communication area A 117 is a communication area B 118, a process C 119 is a file C, and 110 is a data drive section.

Here, the procedure for controlling the processing execution order of the data driving unit will be described: (1) Processing is executed when all input data is in place and output data is invalid.

■ Suppose that the input data is ready when data is input from a file or other process.

■ When processing is completed, input data is invalidated, and when data is created in the output area, output data is valid.

■ Output data becomes invalid if it is output to a file or input by other processing.

Now, in the initial state, data is input to file All and β and communication area A16 is in an invalid state, so 13 is activated. When data is created in the communication area A16 in process A13, the data in the communication area A16 becomes valid, and when process A13 ends, the data in the file All becomes invalid. In this state, the data in the communication area B17 is not valid, so the process C18 is not executed.

Process C18 is executed when the data in communication area A16 and communication area B17 are valid and the file C19 is invalid. Next, data is input to the file All, and an attempt is made to execute process A13, but since the communication area A16 is in the valid state, process A13 is not executed.

On the other hand, data is input to file B12, and processing B14 is performed.
Execute the edge, contact area B17 is valid, and contact area A
16 is also active! Therefore, processing C18 is executed. In this way, the input data of files A11 and B12 are processed code by code until the input data is completed.

(6) As described in detail, according to the present invention, there is no need to program control logic for executing processing under the control of the data driver, and there is no influence on the order of programming. Execution control of desired processing can be easily performed without being overwritten, and software productivity can be improved.
