摘要
采用传统工程方法开发图文办公系统存在开发周期长、维护困难的难题。分析了产生这些问题的原因,提出从具体业务特征中抽象共性特征,并对共性特征(包括独立特征)与具体业务特征分别建模的二次建模方法。应用实践表明,该方法增强了图文办公系统的适应性。
Much problems are rasied under conventional method on OfficeGIS development, such as： delaying of working schedule, difficult to maintain, etc. A new approach named twice-step modeling is proposed to improve the flexibility of the system.Firstly, common features are abstracted from business ones and applied to domain modeling. Then business modeling is following based on instantiation of the domain model. It has been applied to land management in several cities.
