Project Summary

面向对象数据库是对面向对象方法学的发展和运用,是面向对象方法学在数据库领域的具体实现。它以数据库原理为本,以面向对象开发语言为体,解决了面向对象开发过程中对对象的持久化。面向对象数据库的出现,简化了面向对象语言对持久层的编码。开发人员不再需要使用SQL语句,即可完成对象数据的持久化和查询功能。而和同样具备这个能力的对象关系映射方法对比,无需建立表和类,对象和属性的映射。因此在需求和领域模型发生变更的时候,使用面向对象数据库作为持久化开发的业务代码,无需维护映射。同时,数据库与业务程序的同质,即两者都使用同一种面向对象语言开发完成,解决了业务程序与传统关系型数据库通信时,异构系统之间的阻抗失调问题。

oJadb实现了数据库的基本功能,包括对象的增删查改,索引的创建,删除,重建和搜索,以及对事务的支持。省去了视图,触发器,存储过程等在面向对象领域失去意义的功能。作为Java应用系统的数据持久化系统,oJadb省去了Java开发人员数据库建模过程,开发工作从对业务模型设计开始直接进入业务编码阶段,使开发人员集中精力解决业务问题。从开发工作量上衡量,其持久层代码在整个业务代码中占据相当小的比例。
