摘要：The present invention provides a database system capable of dealing with

dynamic changes in an event that vary continuously with time. A database system outputsa retrieval output from data in response to a user's retrieval request on the basis of aretrieval logic. The retrieval logic is allowed to evolve on the basis of a logical model. Thislogical model establishes a general relationship which leads results from conditionsrelating to a group of events that are dealt by a data group. Moreover, a databasesystem optimizes a data structure on the basis of the logical model. The logical modelcan be transferred in a separated manner from the specific data contents of the datagroup. Therefore, the logical model can be exported to another database system of thesame kind, and also imported from another data base system of the same kind.
