摘　　要：在支持航空产品研制的协同设计平台中,满足设计数据库共享模式的平台架构与安全控制结构是两项关键技术。本文在分析设计数据库特殊的管理与共享模式的基础上,提出了基于CORBA的协同设计平台结构,以及基于数据库访问网关的安全控制方法。在数据库访问网关核心技术的研究中,提出了利用CORBA拦截机制保证数据库网关有效性的方法,为增强型安全产品开发提供了一种新思路。本文最后给出了系统实现与性能测试结果。In building a collaborative platform supporting aeronautics product design, the architecture of the platform which satisfies the design databases sharing mode and the security control method are the two key technologies. On the base of analyzing the special management and sharing mode of the design databases, the paper submits the architecture of the collaborative design platform by using CORBA technology and also submits a kind of database access gateway to achieve the security control of the sharing data. In the research of the key technology of the database access gateway, the paper puts forward a method to ensure the effectiveness of the database access gateway based on the CORBA portable interceptor mechanism, which provides a new thoughts for enhanced security product development. The paper also presents the system implement result and efficiency testing result.
