Open Data Services和Socket的应用研究--数据库服务器与应用程序间网络通信接口模块的设计

在数据库应用系统开发时常遇到的问题是如何合理的设计外部进程访问数据库的时闻控制方案，在满足设计要求的响应时问的前提下。把握好系统与网络负载同系统事务响应处理速度之间的平衡关系。但在实际开发过程中对于某些类型数据的响应处理缺乏有效率的解决途径。此类数据采用通常的处理方式往往不能较好地得到解决。基于此，开发了1种由ODS API和Socket缩程的数据库ESP扩展方法，由应用系统主动查询方式变为数据库系统主动通知或推送的方式，从而提供了1种高效率的解决方案。

Application Study Of "Open Data Services" And "Socket"

Issue that meet when database application system is developed is how reasonably devise scheme of time control that outer course call on database.To satisfied its response time that device need,balance relation of system and net beating to system response dealing speed is deal with .But in actual developing process, response dealing of some type data is not available way. Therefore ,we must develop a database ESP extended way by program in ODS API and Socket.By changing from application system initiative inquiring to database system initiative informing or imparting ,hence a high efficient scheme is offered.
