Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a database search method that handles variable-length data, and includes a plurality of hit data.
The present invention relates to a business application for displaying hit data on a screen immediately, and more specifically, to a data storage method in a bibliographic database used in a library system.

(Prior Art) Conventionally, bibliographic data has been registered in a bibliographic database as a variable-length record. When searching this database and displaying the hit data on the screen, set the maximum record length of the variable-length record, read one hit data, divide the read data according to the screen display format, and display the necessary data on the screen. Was output to.

When the display of the first data is completed, the second data, 3
The processing of the data of the case was repeated, and the simplified display screen of the hit data shown in FIG. 3 was output.

Similarly, regarding the display of the search book details display screen shown in FIG. 4, the read data is processed into a screen display form, and then the drawing is displayed.

FIG. 6 shows a flowchart of registration in the bibliographic database and display on the screen.

(Problems to be solved by the invention) By the conventional data registration method in the database,
Always edit the data immediately before displaying the screen (Fig. 6 Step 2
5), the display of data was delayed even though the user had to figure out which data to display on the screen, and this delay increased as the number of terminal users increased.

Further, even when all the bibliographic data is not displayed as shown in FIG. 3, there is a disadvantage that all the bibliographic data (one record) must be read into the memory.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks. Assuming that variable-length data can be handled, a pseudo-variable-length storage method for bibliographic information that improves the display speed of search results and reduces the use of unnecessary memory is proposed. To provide.

(Means for Solving the Problems) In order to achieve the above object, a pseudo-variable-length storage method for bibliographic information according to the present invention is a storage method for storing variable-length data of bibliographic information in a database storage unit. An acceptance processing file storage unit that stores data to be registered, and a variable length bibliographic data of a book stored in the acceptance processing file storage unit are separated by a predetermined number of bytes corresponding to the number of digits to be displayed on the screen. A data editing unit that edits data into a fixed-length multiple record similar to the screen display format by setting one record and a plurality of records to one data, a bibliographic database storage unit, and the data editing unit Database registration means for storing data in the bibliographic database storage unit;
The screen display unit and the bibliography database have a registration number and a repetition number as a primary key of the bibliography data, and the search of the bibliography data locates the target record by the registration number and repeats the repetition from there. A plurality of records of one data is read by referring to the numbers, and the data read screen transmitting means is displayed on the screen display unit.

(Example) Hereinafter, the present invention will be described in more detail with reference to the drawings.

FIG. 1 is a processing diagram showing an embodiment of a pseudo-variable length storage method of bibliographic information according to the present invention.

The reception processing file storage unit 1 stores a file of data before registration in the database. When registering variable-length bibliographic data of a book stored in this file as bibliographic data, the data editing unit 2 separates the data into 35 characters in Japanese, and records 35 characters (70 bytes) as one record. Are stored in the database storage unit 4. This Japanese 35-character delimiter is the number of digits actually displayed on the screen.

Next, how to use the data stored in the bibliographic database in this manner will be described with reference to the search system shown in FIGS. 2, 3, and 4 as an example.

The search processing screen shown in FIG. 2 is a screen in which post search is input and the number of hits is displayed. At this time, a registration number (primary key of the book database) is written in a work area (not shown) so as to know which book was hit.

Next, when the execution key for switching to the simplified display screen of the hit data is pressed, one registration number of the hit data is read from the work file, and the data reading screen transmitting means 5 uses the number as a key and the book database storage unit 4. And edit the necessary data and transmit it to the screen (the line with the item number on the screen in FIG. 3 is the data in the book database).

Next, the data reading screen transmitting means 5 searches the bibliographic bibliographic database. The bibliographic bibliographic database has an index organization having a registration number and a repeated record number as keys as shown in FIG. 5 (b). The screen display is fixed at three lines below the data display line of the book database on the screen in FIG. That is, the search of the bibliographic database is configured such that the target record is positioned by the registration number, and reading and transmission to the screen are repeated three times from there. At this time, the determination unit 7 determines whether or not there is a record of the same data.

As described above, the processing of the data for one case is completed, so that the processing of the second case, the third case to the fifth case is continuously repeated.

Next, in order to display the details of the data displayed in FIG. 3, when the item number on the left side of the screen is input and the execution key is depressed, the detailed display screen shown in FIG. Will be As for the detailed display in this case, the data reading screen transmitting means 5 searches the library database and displays the data, and then reads all the data having the hit registration number registered in the bibliography database. ,
Repeat transmission to the screen.

In addition, data display processing such as lending, return processing, inquiry, reservation processing, etc. can all be performed in the same manner.

(Effects of the Invention) As described above, in the present invention, data registration in the bibliographic database is divided into variable-length data and handled as a plurality of fixed-length records similar to the screen display format. Editing process that must be performed each time output to the CPU can be deleted, which allows the CPU used for editing to be deleted.
Is unnecessary, and the effect on other tasks can be reduced.

Also, if the screen format is understood, it is configured to read the bibliographic data to be displayed by the number of lines, so that unnecessary data is not read, and it is very easy to understand new application settings. effective.
