| 摘要 |
The invention relates to a method and system for real-time processing of large volumes of transaction data by making available a hybrid object-oriented and relational, data base management system (DBMS) for storing said data in optimised data structures in a high capacity central memory. Procedures and functions of user-defined types, which are stored in said central memory, are executed as methods of COM-objects. The optimised data structures are stored as complex objects in the DBMS. Said DBMS comprises a traditional relational DBMS as well as a separate container for storing said complex objects. A SQL request from the client application invokes the stored procedure through the method name of the COM-object, a copy of which is made available in the addres space of the central memory and dynamically linked to the DBMS process.
