面向服务的航天发射场异构数据库集成研究

Service-Oriented Integration of Heterogeneous Databases of Space Launch Sites

在航天发射场信息化发展过程中,异构数据库日益成为制约其信息共享的因素。首先阐述了某发射场异构数据现状,而后对异构数据库集成方法进行了讨论,结合中间件和XML技术,设计了一个面向服务的发射场异构数据集成框架。该框架以数据存取中间件为核心,充分发挥XML跨平台的技术特点和面向服务的松散耦合特性,为发射场解决信息孤岛提供支持。

Heterogeneous databases have become a restriction of information sharing during the development of space launch sites.First,the current conditions of heterogeneous databases of some space launch sites are introduced.Then,the integration methods of heterogeneous databases are discussed.Finally,a service-oriented integration framework is designed using middleware and XML technique.The core of the framework is the data store-access middleware and it provides support for solving information silo by making use of the platform-independent performance of XML and service-oriented loose coupling feature.
