Abstract

PURPOSE:To shorten a retrieving time by transferring a data group interesting to a terminal user previously to a local file and adding local and center discrimination codes. CONSTITUTION:In an example for transferring a data group 18 relating to education out of center information to a local data base, discrimination codes 20, 17 are added to a retrieving picture 19a and a table to be the master of an education table respectively to indicate that the data after the codes 20, 17 are stored in the data base of the local system. When the user selects education while observing the initially displayed index picture plane 19a, the existence of EDUCATION in the local data base is discriminated by the discrimination code 20 on a retrieval table 9 and the education table 18 in the local data base is retrieved.

Description

[Detailed Description of the Invention] [) Already Required] Information retrieval in which data that is frequently searched can be quickly searched by providing means for storing the location of information to be searched along with a search table. method.

[Field of application of the invention]

The present invention is applicable to a system that has a center file and a local file that stores information that is frequently used by a terminal user to search or information for a special purpose among the various information stored in the center file. , relates to an information retrieval method that quickly retrieves data from these files and displays it on a terminal.

The above information search method is commonly used in a system that quickly searches for sensor information and displays it on the display device of the terminal (2), as shown in FIG.

The center (1) and the terminal (2) are connected via lines and placed at separate locations, allowing users to quickly search the information stored there without being aware of the content. It is requested to do so.

[Conventional technology]

In the conventional system, the local database (4) in Figure 5 stores the information required by the terminal (2) individually at the center (1).
) and configure the database. - Using the search command from the keyboard of the terminal (2), first search the local database (4), and if the information is not found, access the center (1) and search the center's database. (
Information is obtained from 3).

〔problem〕

Therefore, there are drawbacks such as it always takes time to search the local database, and the search time varies greatly even though the data has the same attributes.

[Means for solving problems]

An overview of the present invention is shown in FIG. In the present invention, the local database has a search table (9) that is the same as the search table (7) of the center (5) and a local information data table QOI. In addition, the local information data table α [is a unit of attribute group (15
) or (16) to load from the center. As a means of loading, the terminal (6) uses a line, etc. When reading various information in the table from the center (1) to the line or from a specific medium, the local information data table (QO) is stored in the search table (9). Identification codes (15a) and (16a) are added to the stored information and stored in a file.

[For production]

When the file created in this way is instructed to search for the required information from the keypad (1) of the terminal (6), the identification code is first used to search the search table. Access by selecting either local or center database.

This makes it clear which database to access, making it possible to shorten the access time.

〔Example〕

Hereinafter, the present invention will be explained according to examples.

FIG. 3 and FIG. 4 are a search table and a terminal configuration sequence showing an embodiment.

The case in Figure 3 shows an example of transferring education-related data group (18) from center information to a local database, and the identification code (2
0) and an identification code (17) is added to the parent table of the educational table, indicating that the data below is stored in the local database.

Therefore, the index screen (19a) that is displayed first
When the user selects education, pull (18) is searched using the identification code (20) on the search table (9). Note that the identification code may be assigned to all lower-level data. Also, the identification code depends on the number of databases, but if there is one at the center and one at the coffee terminal, it will be "1".
It is expressed by "bit flags of 1" and "10".

FIG. 4 shows an example of the configuration of the terminal.

In the figure, (20) is the modem, (21) is the CPU, (22)
is the program memory, (23) is the display controller, (
24) is the keypad, (25) is the I10 control unit, (26
) is floppy, (27) is local database, (
28) is a communication network, (29) is a display unit, and (30) is a line connection device.

In the illustrated configuration, when transferring a data group from the center (1) to the m terminal via the communication network (28), data is transferred from the floppy disk (26) via the line connection device (31) and modem (20). If so, it is written to the memory (31) via the I10 control unit (25).

The CPU (21) uses a program (22) in a pre-stored program memory to check the data read following the search table, assign an identification code to it, and store it in a local database (27).

Search is performed on the index screen (19a) displayed on the display section (29).
) and specify the number using the keypad (24).

The cPU (21) reads out the search screen to be displayed next according to the designated number from the search table (27) and decodes the attached identification code.

This result allows you to use the local database or
[Effect] According to the present invention, a group of data that a terminal user is interested in is transferred to a local file in advance, and local and center identification codes are added. The difference in search time will be reduced. Furthermore, the present invention can maintain independence in that locally added information can be added or changed independently of the center, as in the conventional system.
