摘要
一、引言确定正确而完整的需求对于大型信息系统的成功开发是至关重要的。随着用户需求越来越广泛,越来越难于确定,人们已认识到,需要一个合适的过程来描述系统的开发任务,需要一种恰当的形式来表示用户需求。
After briefly describing the basic concepts about,object-oriented requirement an- alysis,we present a new analysis technique for information systems in this paper. Using traditional techniques of ERD,STD and DFD to elicit the basic concepts from application domain and applying the conceptual graph theory to establish conceptual graphs,conceptual hierarchies and relationship hierarchies make the analysis procss formaller and it easier to check the consistency of requirements and to translate an unformal model to formal model of the requirements.
