摘要
讨论了在信息系统开发过程中,由系统向用户提供自定义接口,从而允许用户根据自身情况定义满足自身需求的计算公式的重要性和必要性。在介绍了目前常用的几种公式定义方法之后,对其中一种典型方法进行了深入的分析,详细地说明了系统的数据结构模型,并以代理人佣金管理系统中佣金项的计算为例,对佣金项的计算流程,自定义公式的解析规则及过程进行了详细的说明。
This paper discussed the importance and necessities of formula defined by end users according to their own requirement of a system. It is believed that almost all information management systems should supply such a module during it＇s developing cycle. After a brief introduction and Comparison of formula define to the common methods currently used by many management systems, it selects one typical of them analyze thoroughly and illustrate data model of the system. Finally, we take the agent Commission management system, for example to illustrate the calculation process, formulas resolution rules and procedures.
