| Abstract: | The problem of database capability is always the focus concerned by deciders and technician.The most direct and reliable judgement gist to measurement the capability of a system is the response time of the searching time of the database.It thinkes about the searching efficiency of database,analysed part factors which affect the response time of database searching,and studied the optimized methods of Oracle database searching.It also made of a full testing about the study results. |
| Keywords: | oracle database searching efficiency response time |
