Abstract: Data integration is an important problem in building computer applications. This paper introduces and implements a plug-in based solution of heterologous data integration on application systems. In this solution, “data access plug-ins”, which are known as data interfaces, are used to gain heterologous data from different systems and reform these them into unified format according to the business requirements. After that, a framework is applied to manage and control these plug-ins dynamically and consistently. Thanks to the technology of plug-ins, this extendable solution of system integration gains more flexible and dynamic features.

摘要： 数据集成是建立综合电子信息系统所面临的重要问题，该文提出并实现了一种基于插件技术的应用系统异构数据集成方案。该方案以数据访问插件为接口，获取不同系统的异构数据，并转换为集成业务的统一数据格式。在此基础上，采用集成框架对插件的行为进行统一管理，动态控制集成系统的数据访问能力，具有很强的灵活性和动态特性，提供了一种可扩展的数据集成方式。
