NGN业务平台内存数据库的设计与实现

在下一代网络(NGN)业务的运行过程中，由于大量的呼叫同时存在，因此对数据的访问实时性要求高。针对该情况，提出一种内存数据库的设计开发思路，把业务需要访问的表和数据，通过一个二级散列表的方式，在内存中进行统一存储，并对内存中数据的加载、同步、访问接口等进行了实现。该内存数据库已在上线的NGN业务中成功使用，其可靠性、安全性得到了实际检验。

Design and Implementation of Memory Database Based on NGN Service Platform

On the running process of Next Generation Network(NGN) service, large numbers of calls exist at the same time, so it requires high real-time data access. In order to solve this question, an ideal about memory database is put forward. It saves the service data to memory by a two-layer hash table uniformly, and it is implemented that how to load, synchronize and access data of memory database. Now the memory database is applied to on-lined NGN service successfully, and the reliability and security is verified practically.
