| 摘 要： | 分析了地理信息服务之间的耦合性,研究了影响地理信息服务粒度的因素,提出了业务驱动的地理信息服务粒度划分模型。该模型首先从功能模块分离出基本服务,各个功能模块可以看成是组合服务,由功能模块分离出来的就是基本服务;然后在基本服务的基础上设计组件和业务对象;设计完组件和业务对象之后再来设计组合服务。

| Abstract: | This paper analyzes the coupling of the geography information services。 This paper puts forward the granularity-divided model of the geography information services. Above all, this model separates the basal services from the function units. The function units are looked as the combinatorial services. Then designs the subassembly and objects based on these basal services. Finaly designs the combinatorial services based on the subassembly and objects. |
