摘要
工程应用中软件工具的多样性和设计活动的分散性形成了大量异构数据。本文分析了传统的异构数据管理方法的不足,提出使用数据库系统和文件系统结合的管理方法。针对此方法下所形成的异构数据源问题,给出了基于J2EE规范的数据访问对象抽象工厂解决方案。
There are a large amount of heterogeneous data due to the variety of application software and spreading of design. The paper analyzes the deficiency in the traditional method of heterogeneous data management, and puts forward the thought of integrating DBMS and file system. Finally, the data access and abstract factory solution based on the J2EE criterion is presented.
