Abstract

PURPOSE:To efficiently perform retrieval processing by setting plural retrieval keys, and performing single retrieval key designation and plural retrieval key designation in the retrieval processing of data. CONSTITUTION:A corresponding retrieval key file is recognized from an inputted retrieval key value(step 11), and conformed retrieval key data is read by a designated retrieval key(step 12), and rough information is displayed on a retrieval terminal(step 13). When the display request of retrieval key data from the following retrieval terminal is further issued(step 14), repetitive display is performed starting from the retrieval key data following the one read in last time, and a data file is read with a decided retrieval key, then, information is displayed. Therefore, it is possible to perform various kinds of key retrieval and to shorten retrieval time by providing the key file dedicated for retrieval processing.

Description

Detailed Description of the Invention

[0001]

The present invention relates to a data search method,
In particular, it relates to a data search method by filing a plurality of search keys.

[0002]

2. Description of the Related Art A conventional data search method using a plurality of search keys includes a process of determining whether an input search key is a key item of a data file (step 21) as shown in FIG. It has a data read process using a key (step 23) and a process of sequentially reading data files (step 24) to determine whether the data is corresponding data.

Next, the processing procedure will be described. It is judged whether the input search key is a key item of the data file (step 22). If the key item of the file is determined, the data file is read by the input key value (step 23). If it is determined that the file is not a key item, the data file is sequentially read (step 2
4) is performed to determine whether the read data matches the input search key (step 25). If they do not match, this judgment is repeated again (step 2).
4). Then, the data matching the entered key is displayed on the terminal (step 26).

[0004]

In this retrieval method, when performing retrieval processing in a data file item, it is always read sequentially from the beginning of the data file, and whether the retrieved data matches the entered retrieval key. Since it is necessary to judge, there is a problem that the number of data in the data file is large and it takes a very long processing time to search the data behind the data file.

[0005]

A search method according to the present invention recognizes a search key file corresponding to an input search key, and reads a target search data file from data read from the search key file. It is configured to generate a key and read the search data from the search data file.

[0006]

The present invention will be described below with reference to the drawings.

FIG. 1 is a flow chart showing the configuration of the present invention, and FIG. 2 is a data configuration diagram showing an example of the data contents of a key file showing the relationship between various key files and data files. The search key file corresponding to the input search key (step 9) is recognized (step 11), and if it is not the key item of the data file, the recognized search key file is read (step 12) and the screen requesting the search is displayed. For example, the key file information (key value 18 of the key file, data file key value 19, additional information 10) is displayed at a maximum of 20 times at a time, for example. If there is no data that matches the search data requested by the user, the next and subsequent data is read and displayed again on the screen (step 14). When the user determines the search data from the displayed key data and selects it (step 15), the data file key value 19 on the key file is used to index the data from the data file and search for the screen requested to be read. Display the data (step 17).

When it is recognized as the key item 13 of the data file in the search key file recognition (step 11),
The input search key is used to index the data file and read the search data (step 16), and the search data is displayed on the request screen (step 17).

[0009]

As described above, according to the present invention, since the search key of the search data is managed by a plurality of files, it is not necessary to sequentially read in the search processing other than the key item of the data file. This has the effect of reducing the search time.
