摘要： 在SCDMA接入系统的运行过程中，同时存在大量的用户鉴权、呼叫，对数据的访问实时性要求高。针对此情况，提出一种内存数据库的设计开发思路。通过哈希表的形式，把业务需要访问的数据和表加载到内存中，采用统一数据库接口的方式进行数据交互，实现内存与物理数据库之间的数据同步问题。该内存数据库已在上线的SCDMA接入系统中成功使用，其可靠性、安全性得到检验。

Abstract: On the running process of SCDMA access system, large numbers of user authentications and calls exist at the same time, therefore it requires high real-time data access. In order to solve this question, a suggestion of designing memory database is raised up. And this proposal is as this way: the data and tables need to be visited are loaded to memory through Hash table, through which way, achieves the data interaction through unified database interface and makes the memory synchronized with the physical database. Now the memory database is applied to SCDMA access system successfully, and the reliability and security are verified practically.

Key words: memory database, SCDMA access system, Hash table, unified database interface
