Improving Database Performance Optimizing the database Optimizing the database Proposed Method for Database Performance Tuning Proposed Method for Database Performance Tuning Officer search request distributed across multiple servers Officer search request distributed across multiple servers A dispatcher do load balancing A dispatcher do load balancing Request for insert send to whole servers Request for insert send to whole servers Request for search send to only one server Request for search send to only one server

22. 22 IV. Experimental Result(1)

23. 23 V. Conclusions(1) With growth of infraction manual method goes to be unusable. With growth of infraction manual method goes to be unusable. Police communication Police communication Security and be quick Security and be quick Anywhere, anytime Anywhere, anytime

24. 24 V. Conclusions(2) we propose a secure traffic police data center we propose a secure traffic police data center protect and establish their communication in authentication and confidentiality protect and establish their communication in authentication and confidentiality Introduce our method tuning Introduce our method tuning minimize the response time minimize the response time It can be extended to the other mobile information systems It can be extended to the other mobile information systems
