基于复杂对象的数据快速访问方案的设计与实现

摘要

This article introduces the way of quick data access based on complex object,with which the transparent data access means for the complex relational database is produced for software developers.With a relation-decomposing mapping method,a complex business object which supports business process is produced to shield the logic of database or data model.With this data access method improving the efficiency of application software development,business code is easily written and data access of each function module code is decoupled greatly.Finally,a data prefetching and data caching strategy is introduced to improve data access speed.%文章介绍了基于复杂对象的数据快速访问方法,为软件开发人员提供一种针对复杂关系型数据库的透明数据访问手段。通过对数据库内实体及关系的解析,生成能支持业务流程的复杂对象,从而屏蔽数据库或数据模型,方便业务流程的编写以及系统各功能模块之间数据访问解耦,提高业务应用软件开发效率。最后,通过对查询数据的预取和缓存等优化机制,加快数据访问的速度。
