GIS功能仓库构件连接器的设计与实现

Design and implementation of component connector in GIS function warehouse

功能仓库中的异构构件之间的连接普遍隐式地存在于构件中,不利于软件构件复用。本文重点研究功能仓库中异构构件连接的问题,提出构建显式构件连接器的方法,增强功能仓库对功能构件的管理和集成能力,并且给出了构件连接器的设计和实现。同时,本文将该方法应用于GIS中间件构件的管理中,进一步增强了GIS中间件集成多源异构空间数据的能力。

This paper focused on the component connector in the function warehouse. It was pointed out that the component connector generally implicitly existed in the function ware house, which was not good for the component reuse. In order to enhance the capacity of managing and integrating the component for the function warehouse, a method of setting up explicit component connector was put forward, and the design and implementation of the component connector were discussed in details. Meanwhile the idea was applied in the management of the components of GIS middleware, of which the ability to integrate multi- source spatial data was further enhanced.
