摘要 随着通信技术和网络技术的发展,嵌入式移动数据库正成为数据库领域的一个新的研究方向。针对嵌入式移动数据库中频繁断接性、低带宽等特性,介绍了数据广播和客户缓存两种用于嵌入式移动数据库中处理断接操作的方法,提出了基于语义的查询优化策略。研究表明,该策略能够提高移动数据库查询的效率。 With the development of the communication and network technology,the embedded mobile database is becoming a new research direction in databse fields.There are frequent disconnection and limited bandwidth in embedded mobile database.This paper introduces two methods for disconnected operation and discusses a new query optimization strategy based on semantic in embedded mobile database.By the researching on the strategy,the mobile database query is optimized.
