摘要
对ERP软件中出现的应用系统难于改变及扩展的问题,提出了一种新的树状数据库设计模型,叙述了该模型的定义及设计原则。通过建立某企业产品信息系统数据库模型实例,对比ERP软件中传统数据库设计方法,分析了两种模型各自的优缺点,并最终得出该模型更加适用于应用复杂,业务规则多变,应用可能发生扩展的数据库系统。
In order to solve the difficulty to change and expand the application system in ERP software, a new tree-like database design model is proposed, in which the definition and the design principle are narrated in detail. The new model is proved to be more suitable for the complicated and changeable database systems whose applications are possible to expand, by giving an example of a company＇s product information system model and comparing it with the traditional design model in ERP software.
