摘要： A database processing system for analyzing a query issued to a database to generate a corresponding execution procedure for performing database processing in accordance therewith. A plurality of columns for storing data each constituted by a set of instances and conditions concerning the instances constituting the plurality of columns are entered. A query is inputted which contains a predicate for evaluating whether a set of instances which meet the designated conditions and which can be identified with the same subscript exists among the sets of instances stored in the plurality of columns. In response to the query, a decision is made as to whether or not an index has been generated for one or plural columns specified in the query predicate. When the index is generated, the index is accessed to acquire an identifier of table data which is “true” for a predicate. Unless the index is generated, a decision is then made as to whether or not column data acquired by accessing the database meet the conditions specified in the predicate contained in the query.

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 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 user defined ADT function (to be implemented by an embedded module assigned to the function) is executed with module calling triggers other than the execution of the ADT function described in an SQL statement in a database management method which allows the user to define a data type. By creating a proper execution procedure command package, an embedded module implementing an ADT function can be executed even if the function is defined in a format to return execution results as a set. The database processing method includes an ADT function analysis for selecting a procedural model for creating a proper execution procedure command package in accordance with an evaluation style and a non-ADT function called embedded module analysis for adding information on embedded modules called on module calling triggers other than execution of ADT functions. Examples of module calling triggers other than execution of ADT functions include module calling triggers specified by embedded module defining information which includes the evaluation style of the embedded module in addition to the module calling triggers.
