| Abstract: | In view of the demand of distributed query in network environment, the J2EE technology is combined with the theory of distributed database, and the model of the query system of distributed database based on J2EE is put forward. Based on the case study of the query system of capital assets, the development process of the query system of distributed database based on J2EE is discussed systematically,and such issues as transaction processing and query optimization are studied emphatically. Finally,the tactic of query optimization is presented to meet the demand of the query system. |
