一种基于WebGIS的"对象-用户-应用"集成框架模型

经典的集成技术解决了应用间的粗粒度集成问题,而企业的实际应用表明,特别是基于GIS的应用,需要的是以用户为中心、以GIS对象为导航目标以及与二者紧密相关的应用的细粒度集成。采用元数据与元模型驱动技术,提出了一种基于"对象-用户-应用"的细粒度集成框架模型。该模型基于GIS空间对象实现了不同权限的用户与所关心对象以及与该对象相关视图的有机集成;此外,该模型还能够实现该平台应用之外的其他应用的集成。该模型在大庆油田这样的特大型企业的多专业、多学科的集成中得到应用,实现了各种应用与GIS空间对象以及用户的真正集成。结果表明,该细粒度的集成框架能很好地解决特大型企业基于GIS对象导航的细粒度应用集成问题。

A Kind of Object-user-application Integration Frame Based on WebGIS

Classical integration technique resolved integration among applications.Exactly,this technique resolved coarse integration among applications.Enterprise application shows that enterprise needs refine-grain integration which can implement integration of user-centred object-user-application.A kind of object-user-application integration frame is proposed based on WebGIS by means of meta-data and meta-data-driven technique.By means of GIS space objects,The frame can integrate different users and interested users and viewers related to the user and objects.Besides the frame is able to integrate external applications.This integration frame is used in Daqing Oilfield for integration among mutli-discipline and multi-business.Application results show that this integration frame provides refine-grain applications integration based on WebGIS in a large scale enterprise complicated applications.This refine-grain integration frame is able to apply to other domain application integration.
