摘要： 根据国家“863”项目中对复杂对象的存储与建模的研究,一种JavacollectionO/Rmapping的实现方法被提出,该方法可以在mapping的过程中保留collection的特性,并且由于在mapping时整合了collection在Java中的继承层次关系,因此在查询时可以有效分地进行类型转换。

Abstract: Based on the researching of complex object modeling and storage, a solution of O/R mapping for java collection, which can remain these characteristics when mapping , is introduced. Besides that, by integrating collection container inheritance into the database, it can effectively transform collection container from subclass to superclass when retriving collection from the database.
