基于三层结构的业务管理系统设计方法

Design Method of Business Management System Three-Tier Structure

针对业务管理系统开发过程中普遍存在的需求多变、目标难以度量以及快速交付和可持续发展的矛盾等问题,笔者在产品设计阶段进行方法改进。在产品设计阶段依序开展数据建模、交互建模以及接口定义3部分工作,并与实现阶段相衔接,形成完整的业务管理系统开发方法。利用数据模型、交互模型、应用程序接口定义3个成果,在设计阶段实现精确和具有弹性的产品设计定义,最终实现清晰的项目目标、稳定的执行过程、可持续发展的基础3个关键目标。

In view of the common problems in the process of business management system iteration, such as changeable requirements, difficult to measure objectives and the contradiction between rapid delivery and sustainable development, the author improves the method in the stage of product design. In the stage of product design, three parts of work are carried out in sequence: data modeling, interactive modeling and interface definition. They are connected in series with each link in the implementation stage to form a complete business management system development method. Using data model, interaction model and application interface definition, we can achieve precise and flexible product design definition in the design stage, and finally achieve three key objectives: clear project objectives, stable execution process and the basis of sustainable development.
