摘要： In a database management system including a request reception server and a plurality of execution servers, each having a plug-in program module incorporated by a user, the request reception server analyzes a processing request from the user to determine whether or not the plurality of execution servers require currently unidentified input parameters when executing external functions in their plug-in modules, based on a definition information table created from descriptions of interface specifications for the plug-in program modules. When it is determined that the execution servers require such input parameters, an external function in the plug-in program module in the request reception server is executed to previously acquire the unidentified input parameters. The request reception server creates an execution processing procedure code, to be executed by the plurality of execution servers, assuming that the unidentified input parameters have already been inputted, and passes the execution processing procedure code together with the input parameters acquired by the request reception server to the plurality of execution servers.

摘要： A request accepting server accepts a processing request of data of a predetermined type, analyzes the request, and allocates a process corresponding to the request to either one of the request accepting server and at least one database processing server. A handle is a control block to manage a storage area of data as a processing target and has a server in which the processing target data has been stored and information regarding its storing position. When the processing target data corresponding to the processing request is processed in accordance with the processing request, the request accepting server executes a process according to the processing request by using a handle regarding the processing target data. When an entity of the processing target data is necessary, the entity of the processing target data is obtained on the basis of the handle and is processed.

摘要： In a parallel database system having an execution device on a front end side and a plurality of execution devices on a database operation side (hereinafter referred to as the “divided data side”), the front end side analyzes a definition statement of a routine such as a function or a procedure inputted from a user to create routine execution process instructions for executing the routine. Simultaneously, the front end side determines whether or not a database operation statement is contained in the routine, and creates check information indicative of the determination result. The front end side analyzes a query statement inputted from the user to create a first query execution process instruction to be executed on the front end side and a second query execution process instruction to be executed on the divided data side. When the divided data side executes the query in accordance with the second query execution process instruction, a routine containing no database operation statement in the second query statement process instruction is executed on the divided data side.
