Abstract

PURPOSE:To transfer a large quantity of data with high efficiency by one instruction, by dividing a controlling sentence into plural data and an instruction for procession when the controlling sentence is decoded. CONSTITUTION:A program incorporated into an application program part 2 is retrieved by an interpreting part 3. If the program is equal to a relational operation sentence, only the data part is developed to plural call sentences. Then the instruction is turned into a call sentence and stored to an objective program part 4 in the form of an objective program. Therefore, the part 4 stores plural data as call sentences respectively. These data are stored in a storage part 8 via an interface 7, then transferred to a file 6 by one instruction. Thus it is possible to transfer a large quantity of data by increasing the storage region of the part 8 and the number of buses as desired between the interface 7 and a relational data base control system 5.

った。(b) Prior Art and Problems Figure 1 is a block diagram of a conventional relational database system, and Figure 2 is a flowchart showing the operation of a conventional translation unit, where l is a processing unit, 2 is an application program unit,
Reference numeral 8 indicates a translation section, 4 indicates a target program section, 5 indicates a relational database management system, and 6 indicates a file. The application program unit 2 contains an application program, and this application program is processed by the translation unit 3 as shown in FIG. That is, it searches the contents of the application program, tests whether it is a relational database manipulation statement, and if it is a relational database manipulation statement, considers it a call statement, and determines whether this call statement is below the data transfer tolerance value. However, if the following is true, input this operation statement into the target program section 4. If the value is greater than or equal to the allowable value, an error is detected and the process is terminated abnormally. Also, if the application program is not a relational database operation statement, general translation processing is performed and this is input into the target program section 4. As mentioned above, the relational database operation statement is a call statement limited to the data transfer tolerance value or less, and is transferred to the file 6 via the relational database management system 5.In order to transfer a large amount of data, multiple calls are made within the application program. There was a drawback that operation statements had to be created.

This is achieved by a data transfer control method characterized in that the plurality of data are stored in a storage area and transferred to a file by a command call statement.

The explanation will also be omitted. In the figure, 7 indicates an interface mechanism section, and 8 indicates a storage section. The translation section 3 of the present invention operates as shown in FIG. That is, an application program is searched, and if it is a relational operation statement, only the data part is expanded into a plurality of call statements, and the instruction is expanded into one call statement, which is stored in the target program section 4 as a target program. Therefore, a plurality of pieces of data are stored in the target program unit 4 as call statements, and one
Instruction call statements are stored. This is different from the conventional method, in which an instruction and data form a pair to form a call statement. These plural pieces of data are once stored in the storage unit 8 via the interface mechanism unit 7, and transferred to the file 6 via the plural data binder interface units 7 and the relational database management system 5 by one command. Therefore, by increasing the storage area of the storage section 8 and increasing the number of bus lines between the interface mechanism section 7 and the relational database management system 5 as required, it becomes possible to transfer a large amount of data.
