| Abstract: | The principles on the optimization of semi-join operation,and the algorithms of semi-join program were analyzed for this distributed data base system.The implementation strategy of semi-join computation was improved and enriched with a new one,and their expense and profit were analyzed in detail.The algorithms having been improved can reduce the response time during the query process. |
