Abstract
When a database server has retrieved an object of an object storage area to be subjected to retrieval in response to a database query requirement, it stores identification information of an object of a query result in an identification information area. The database server functions to generate an object containing its query condition and identification information referring to identification information of an object of the query result in the identification information area and register the object in the object storage area. On the basis of information of a new query condition, a database client requires the database server to retrieve an object containing a condition of a retrieve already conducted and its retrieval result. As a retrieval result, the database client receives a query result for the condition of a query already conducted squaring with the new query condition.
