Sql server mobile also provides multiple - connection access to a database , multiple - column indexes and matching index limits , transaction support , referential integrity , 128 - bit file - level encryption and password protection , and a query optimizer Sql server mobile还提供对数据库的多连接访问、多列索引和匹配的索引限制、事务支持、引用完整性、 128位文件级加密以及密码保护和查询优化器。
With the development of cti 、 communication 、 network 、 multimedia and distributed compute technology , new type connect center will appear one by one . at present , multi - connection and distributed service center represent the direction of customer service center development 随着cti技术以及通信、网络、多媒体和分布式计算技术的发展,新型的连接中心将不断出现;目前,分布式多连接服务中心代表了客户服务中心的发展方向。
In this article , call center and cti technology 、 ngn system structure and softswitch technology are described in detail , the domain framework of multi - connection service center platform based on cti and softswitch technology is discussed . and then the system structure of multi - connection service center platform is put forward 本文具体描述了呼叫中心和cti技术、下一代网络体系结构和软交换技术,然后详细讨论了基于cti和软交换的多连接服务平台的领域框架,并在此基础上得到了多连接服务平台的整体构架和体系结构。
On the base of implementing greedy algorithm , we put hi - ward an idea of using genetic algorithm into query optimization because of the localization of traditional optimization algorithm while processing multi - join query . moreover , we discuss a series of essential query optimization problems . we also present the test results on the pefformance of optimizer and give the analysis of them 由于传统查询优化算法在处理多连接查询时在性能或优化结果上得不到好的效果，在实现greedy优化算法的基础上，本文提出将遗传算法应用于查询优化中，从而解决多连接查询的优化问题。
