JPH0337720A - Data chaining system for dictionary system - Google Patents

Abstract

PURPOSE:To extend the part to be automatically generated of a program to improve the productivity by taking in specifications of data chaining at the time of referring to the attribute of an item in a dictionary. CONSTITUTION:A dictionary 1 includes an item of each item name; and when the item includes specifications of data chaining, it includes the pointer to link data to a specification data base 2 and the specification data base 2 includes specifications of actual data chaining. An expanding means 3 reads in a source program, and the means 3 takes out the attribute when the dictionary 1 is referred in this program, and the means 3 takes out specifications of data chaining from the specification data base 2 and expands them in the source program when specifications of data chaining exist in the program. A generating means 4 generates a logic to be actually operated based on expanded specifications. Thus, the part to be automatically generated of the program is extended to improve the productivity.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a computer software development support system, and particularly to a terminology management dictionary thereof.

(Prior art) In conventional terminology dictionaries of this type, for a certain item in a program, attribute information is retrieved from the dictionary based on the item name or item format name, and is expanded into the source program as an attribute of that item. was.

(Problem to be Solved by the Invention) In the conventional dictionary system described above, no processing is performed other than retrieving attributes for items, listing and managing them, so in order to further improve productivity, further The disadvantage is that additional information needs to be managed and deployed.

An object of the present invention is to store items added to a dictionary system and specifications for data chaining related thereto in a specification database, and to extract related specifications in the specification database from the item name in the dictionary, and to create a source program. By inputting the data chain specification using a dictionary, extracting it into a program, inputting the expanded program and generating logic that actually operates, the above drawbacks can be removed and productivity can be easily improved. The purpose of the present invention is to provide a data chaining method for a dictionary system configured to enable data processing.

(Means for Solving the Problems) The data chaining method for the dictionary system according to the present invention is constructed by specifically including a specification database, a linking means, a developing means, and a generating means.

The specification database is for storing existing items and specifications for data chains related to the items.

The link means is for linking an item name in the dictionary to a related specification in the specification database.

The expansion means is for inputting a source program, extracting data chain specifications using a dictionary, and expanding it into a program.

The generation means inputs the expanded program and generates logic that actually operates.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a data chaining method in a dictionary system according to the present invention.

In Figure 1, 1 is a dictionary, 2 is a specification database, and 3
is an expansion means, 4 is a generation means, 11 is a source program, 1
2 is an expansion program, and 13 is a generation program.

FIGS. 2 to 5 are explanatory diagrams showing examples of actual programs, respectively, and show how the specifications of the data chain are expanded to generate the program.

In FIG. 1, dictionary section 1 includes items for each item name, and if the item includes a data chain specification, it also includes a pointer for linking the data to the specification database. The specification database 2 contains specifications of actual data chains.

The expansion means 3 reads the source program, and if there is a reference to a dictionary in the source program, extracts the attribute, and if there is a data chain specification, extracts the data chain specification from the specification database. Expand into source program.

The generating means 4 generates logic (instruction seating) that actually operates based on the developed specifications.

FIG. 2 shows an example of an actual source program before expansion. FIG. 2 shows that the input data from the screen includes the product number, customer number, and quantity.

FIG. 3 shows an example of a data chain specification. Third
The upper part of the figure shows that chaining to the product master file is performed. When the upper row is specified as the product number specification, the record of the product master file is read using the data 1 product number l. The lower row shows that chaining is similarly performed for the customer mask file.

FIG. 4 shows a state in which the specifications are developed into a source program.

FIG. 5 shows how the source program shown in FIG. 4 is read by the generating means 4 and developed into an instruction sequence.

In FIG. 5, the command sequence for reading the product master file and the command sequence for reading the customer master file are the parts generated by the developed specifications.

(Effects of the Invention) As explained above, the present invention expands the automatically generated part of the program by further incorporating data chain specifications when referring to the attributes of an item from a dictionary.
This has the effect of increasing productivity.
