| 摘要: |
| 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。 |

| Abstract: |
| The existing integrated methods are mainly aimed at the layer of database system. In view of the shortage of those methods, the integration method in the application layer was focused on. According to a new perspective of access control for the database application system, the access control layer was separated from the application layer. A new method called as “fusion” access control was put forward. Based on the method, a simplified integration method of heterogeneous database application system was proposed. An example was shown about how to apply the simplified integration method to achieve the integration of heterogeneous database application system, and the advantages of the new method were verified by a comparison analysis. |
