为准确表达客户需求、更好地与用户沟通并全面描述业务对象,提出了基于纬度建模的信息系统建模方法。该方法首先采用纬度模型描述用户需求,并采用IDEF0技术建立系统功能模型;针对纬度模型和多数据源建立IDEF1x模型,以指导数据库设计;通过统一建模语言技术对IDEF0中的节点进行业务链描述,并建立对象模型以指导软件系统设计。最后,以某钢铁企业的成本管理系统设计为例,通过分析成本管理业务模型,详细阐述了该建模方法对成本管理系统的设计过程的支持。实际应用证明了该方法的有效性和可行性。
To accurately depict consumer requirements and better communicate with consumers so as to describe business objects comprehensively, an information system modeling method based on dimension modeling was proposed. Firstly, dimension model was adopted to represent consumer requirement and IDEF0 technology was adopted to set up system function model . Then IDEFlx was constructed to guide database design for dimension model and data sources. Unified Modeling Language (UML) was applied to describe leaf nodes in IDEF0 for constructing object-oriented model, which would guide software system design. Finally, after analyzing a cost management business model of a steel enterprise, information system model based on the dimension model was described in detail on how to support design process of cost management system. Application of this method proved to be feasible and effective.
