摘要： A database processing method for defining and operating data of file reference type which references a file. A column data insert request for specifying position information indicative of a storage location of a file and watch information for watching the file is received from a database client. A request for watching a file indicated by the position information is issued in accordance with the watch information. The position information and the watch information are stored in a database. The foregoing operations permit data in an external file placed outside a database to be treated as data equivalent to ordinary column data stored in the database to improve the integrity of the database.

摘要： A parallel database system retrieval method and system for transferring from database operation servers to a front end server only those data items that are used in subsequent processing, thereby shortening the query time when the unused data are massive. The invention allows an initial retrieval query to transfer only location information about the target data from a database operation server to the front end server. Using the location information the invention permits a subsequent query to get variable-bound location information so that the latter query will retrieve a desired sub-data item according to the acquired location information and dictionary information about the sub-data item locations within the data.

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.
摘要翻译：在具有前端侧的执行装置和数据库操作侧的多个执行装置（以下称为“分割数据侧”）的并行数据库系统中，前端侧分析例如作为从用户输入的函数或过程，以创建用于执行该例程的例行执行处理指令。同时，前端侧确定该例程中是否包含数据库操作语句，并且创建表示确定结果的检查信息。前端侧分析从用户输入的查询语句，以创建要在前端执行的第一查询执行处理指令和要在分割数据侧执行的第二查询执行处理指令。当分割数据侧根据第二查询执行处理指令执行查询时，在分割数据侧执行在第二查询语句处理指令中不包含数据库操作语句的例程。
