Distributed Memory Database Systems Design Implementation And Application

Theory and technology of database develop very quickly and are applied to all over domains. Traditional database has succeeded in traditional domain. But mobile switch system is high real-time and stability, common database can not meet these needs. Now we are needing Memory Resident Database to meet these needs.The project is required to provide new DBMS with the performance of real time and high efficiency over now old DBMS.This Memory Resident Database Supply these features:Definition of data(table, index, queue et), operation of data(insert, delete, modify, search); synchronization of data: Data synchronous abilty is pivotal function to distributed DBMS(synchronization of static data, dynamic synchronization between master processor and slave processor); database power-on; Saving and Loading of database etc. The last two abilities are not recommended in this paper.And two applications are introduced in this paper. They are IP resource management, and VLR Mobile user data auto backup. They both build on Memory Resident Database.
