基于UCM的需求建模技术

Based on UCM Demand Modeling Techniques

用例在需求描述方面的两大不足:需求的描述不够形象直观;需求所建立的模型与系统的分析和设计阶段的模型存在着较大的鸿沟。为了提高需求描述的直观性和交互性,并尽量减少需求描述中可能造成的需求不一致的现象,对现有的需求建模方法改进后进行需求建模。用例建模技术能够较为全面地覆盖用户的功能性需求,而用UCM来建模场景既能保证模型的直观性,又能保证需求模型和后续的分析设计模型不会有较大的距离。

Two main disadvantages of the use cases demand description: description of the requirements is not enough visual image;demand that the model and the system analysis and design phases of the model there is a big divide.In order to improve the the Requirement Description intuitive and interactive,and to minimize the demand may cause inconsistencies in the requirements description,requirements modeling improvements to existing requirements modeling methods.Use case modeling techniques to more comprehensive coverage of the functional requirements of the user,and to use the UCM modeling scenarios can guarantee the intuitive nature of the model,but also ensures that the demand model and subsequent analysis and design model does not have a large distance.
