摘要: 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。

Abstract: 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.
