异构数据库应用系统集成的简化方法

针对现有集成方法主要面向数据库系统层面的不足,重点讨论面向应用系统层面的集成方法。通过引入数据库应用系统的访问控制新视角,将访问控制层从应用层中划分出来,继而提出融入式访问控制技术,并基于该访问控制技术提出一种新的异构数据库应用系统简化集成方法。通过实例展示了如何应用简化集成方法实现异构数据库应用系统的集成,并通过对比分析验证了新方法的优势。

A Simplified Method for the Integration of Heterogeneous Database Application System

The database application system (DBAS) is widely used in diverse domains, and plays an extremely important role. However, the continuous growth of enterprise, adjustment and change of inside and outside the organization, result in the occurrence of many heterogeneous DBAS. How to effectively integrate these heterogeneous systems has become a hot spot of integration field. The existing integrated methods are mainly aimed at the layer of database system. In view of the shortages of those methods, this paper mainly focuses on the integration method in the application layer. According to a new perspective of access control to DBAS, this paper separates the access control layer from the application layer. Then a new method called as "fusion" access control is put forward. Based on the method, this paper put forward a simplified integration method (SIM) of heterogeneous DBAS. Finally, an example shows how to apply the SIM method to achieve the integration of heterogeneous DBAS, and the advantages of the new method are verified by comparison analysis.
