发布/订阅(pub/sub)技术具有异步以及松散耦合的特点,可以使信息的生产者和消费者在时间、空间和控制流等方面完全解耦,适应目前动态多变的大规模分布式信息系统集成的需求.将带语义数据模型(SDM)引入到pub/sub系统中,提出了一种基于pub/sub机制的信息集成模型(PIIM),并针对信息集成的特点设计了适合PIIM的信息订阅语言,将不同信息源中的信息进行整合,建立统一的信息描述方式和访问操作规范,以统一的视图提供给用户,提供一种解决信息集成的核心问题有效途径.实验结果表明,该系统具有较高的订阅匹配效率.
髮佈/訂閱(pub/sub)技術具有異步以及鬆散耦閤的特點,可以使信息的生產者和消費者在時間、空間和控製流等方麵完全解耦,適應目前動態多變的大規模分佈式信息繫統集成的需求.將帶語義數據模型(SDM)引入到pub/sub繫統中,提齣瞭一種基于pub/sub機製的信息集成模型(PIIM),併針對信息集成的特點設計瞭適閤PIIM的信息訂閱語言,將不同信息源中的信息進行整閤,建立統一的信息描述方式和訪問操作規範,以統一的視圖提供給用戶,提供一種解決信息集成的覈心問題有效途徑.實驗結果錶明,該繫統具有較高的訂閱匹配效率.

There are asynchronous and relaxed couplings in publish/subscribe technology which may completely decouple producers and consumers of information with respect to time, space and control of flow. Adaptation to the requirement of existing cosmically dynamic distributed information integration systems can be done, by introducing the semantic data model (SDM) into the publish/subscribe system. A publish/subscribe-based information integration model (PIIM) can also be applied in the system. In light of the character of information integration, an information subscription language suitable for PIIM was added to the information integration system based on publish/subscribe. Information from diverse sources was trimmed in this system, and unified information description methods and access operation specifications were established, providing users with a unified view. This is an efficient way to solve the information integration problem. Experiments showed that this system produces good results.
