基于对象数据库的扩展Java集合框架

EXTENDED JAVA COLLECTION FRAMEWORK BASED ON OBJECT-ORIENTED DATABASE

常规的数据持久化方法是通过对象关系映射把对象存储到关系数据库中,但是易用性和效率一直是个问题。提出了一种更加方便、性能更强的方法,即用对象数据库来存储海量数据。然而目前对象数据库的使用还不是非常广泛,不少程序员可能还不了解对象数据库的使用。提出的基于对象数据库的扩展Java集合框架(Java Collection Fram ework),可以使程序员操作对象数据库就像使用普通的Java集合框架一样方便,而且在性能上也优于普通的关系数据库。

Conventional data persistence technology is to store the object to relational database through object-relation mapping,but its easy-use performance and efficiency always remain problems.In this paper,we introduce a more convenient alternative with higher performance：i.e.,to store mass data to object-oriented database.However the use of object-oriented database may be not well known by quite a few programmers since it has not been commonly used at moment yet.Thus we propose an extended Java collection framework based on object-oriented database,through which the programmers can operate the object-oriented database as using common Java collection API.The performance of persistence is also enhanced compared with using common relational database.
