Abstract

PURPOSE:To make it possible to change the data retrieving method or data updating method of a data retrieving system without correcting a program. CONSTITUTION:One of plural retrieving methods is selected from reference control tables displayed on a screen, a retrieving control table corresponding to the selected retrieving method is displayed and one of processing functions corresponding to a processing state to be referred out of plural processing states in the table is selected and executed. After executing the function, the succeeding processing state is referred based upon the succeeding processing state number written in the table and one of processing functions corresponding to the referred processing state is repeatedly selected and executed. In the case of changing the retrieving or updating method, the succeeding processing state written in the table is rewritten.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data retrieval system, and more particularly to a data retrieval system that searches data using a plurality of search methods, outputs the search results using a plurality of response methods, and then updates the data.

0002

[Prior Art] Conventionally, this type of data retrieval system
The program will be modified to change the way data is searched and updated.

0003

[Problems to be Solved by the Invention] In the conventional data search system described above, the search method and data update method are changed by modifying the program, so there is a problem in that the number of man-hours for modification is large and functions cannot be changed efficiently. There is a point.

0004

[Means for Solving the Problems] The data search system of the present invention searches for data using a plurality of search methods, outputs search results using a plurality of response methods, and then updates the data. A basic control table that displays search method types as a table for selecting one of the search methods, and multiple processing functions for each of multiple processing states corresponding to each of the search methods in this basic control table. and a search control table for setting the next processing state after execution of the selected processing function, and the search control table for the search method selected by the basic control table. After the selected processing function is executed, the processing function of the next processing state is repeatedly selected, and the setting of the next processing state in the search control table is changed according to the specification.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an example of a basic control table used in the present invention, and FIG. 2 is a block diagram showing an example of a search control table used in the present invention. The basic control table in FIG. 1 is composed of a plurality of pairs of search methods and their function codes. The search control table in Figure 2 allocates the processing status name and its number indicating the processing level vertically, and the processing name and its number indicating the processing content horizontally, and the intersection of each horizontal column and vertical column is The processing status number is set.

FIG. 3 is a processing flow diagram of an embodiment of the present invention. The processing flow will be explained with reference to FIGS. 1 and 2. First, the basic control table shown in FIG. 1 is developed, and a function code corresponding to the search method is selected from the search method menu displayed on the screen (steps 1 and 2). Next, check whether this function code is 99 (meaning end in this example) (step 3), and if it is not 99, search the search control table corresponding to the specified function code, function code 1 in this example. The search control table A is selected and the search control table shown in FIG. 2 is developed (step 4). Here, the first process after expanding the search control table is process state number 1.
, and the first line of processing state number 1 is referred to (step 5). Next, a process is selected on the search control table screen (step 6). At this time, the number at the intersection of the horizontal column of the processing number state number currently being processed and the vertical column of the processing number selected on the screen indicates the processing state number to be referred to next. Here, it is checked whether the number at the intersection is 90 (step 7), and if it is 90, the search is ended and the process returns to step 1. If the number of the intersection is other than 90, the process of the selected process number is executed and then the row of the processing state number of the number of the intersection is referred to (steps 8 and 9). Then, return to step 6 and repeat steps 7, 8, and 9. For example, in FIG. 2, when execution of process number 3 is selected at the process level of inputting search conditions for process state number 1, the list screen for process state number 2 is referred to after this execution. If the user selects the end of the search for process number 1, the next process status will be 90, and the process returns to step 1, where the basic control table is expanded. If the detailed screen with process number 6 is selected, the process status to be referred to next after execution of the process will be the detailed screen column with number 3.

[0008] Next, we will explain the functional changes of the search method and data update method with reference to FIG.
Search condition input, list screen, update, deletion, search distribution display A
, B, and C, but if you want to add a new registration function here, add " in the 7th column, 3rd row of the search control table.
4".Also, if you want to delete the search end function from the functions on the details screen, just delete "90" in the 1st column, 3rd row of the search control table. Returning to Step 1 of 3, the modified search control table is expanded again in Step 4, and the modified menu is displayed to complete the addition/change of the search method and update method.

[0009]

As explained above, the present invention allows the search method and data update method to be changed by rewriting the search control table even while the program is running, thereby simplifying the change work. This has the effect of increasing efficiency, reducing man-hours, and preventing troubles due to program modification errors.

Claims (1)

[Claims] Claim 1: In a data retrieval system that updates data after searching data using multiple search methods and outputting search results using multiple response methods, a search is performed to select one of the multiple search methods. A basic control table that displays the type of method as a table, and one of the plurality of processing functions for each of the plurality of processing states is selected corresponding to each of the search methods of this basic control table. and a search control table in which a processing state to be performed next after execution is set, the search control table for the search method selected by the basic control table is displayed, and after the selected processing function is executed, A data retrieval system characterized in that the selection of a processing function for a next processing state is repeated, and the setting of the next processing state in the search control table is changed according to a specification.
