| Abstract: | In application system,espically in On-line System with transaction processing,data query and the speed of the query have become the most import standard to judge the performance of the application system.To improve the query speed of data in Community Health Care System,we make use of the partial-order relation to slove the problem,and analyze the influence of different pertial order on the speed of the query. |
