摘要： 电信领域已成为数据密集型行业，需要高性能的数据库系统作为支撑系统，基于磁盘的数据库系统不能满足“实时”、“近实时”访问数据库的需求，将数据库核心数据驻留在内存中，可以使用内存数据库来满足需求。Hash索引是数据库系统中广泛使用的索引技术之一，它能够快速地访问数据，易于设计和实现。该文根据内存数据库的特点，为电信网管系统的内存数据库设计并实现了Hash索引。

Abstract: Telecom has became a data-intensive industry, which enlists the support of high performance database. Disk-resident database(DRDB) can’t satisfy the demand of real-time or nearly real-time performance, so to design a kind of new database system, in which "core data" reside in main memory is considered, is needed. Hash index technique is a kind of index technique, used in database system, which can quickly access data, easy to design and implement. According to the features of main memory database, this paper designs and implements a kind of Hash index used in telecom network’s main memory database system.

Key words: MMDB, Hash index, disk-resident database(DRDB)
