全功能点在SOA系统规模估算中的应用

摘要

Size estimation is the basis of project estimation. However, no effective solution is proposed with respect to the size estimation in an Service-Oriented Architecture(SOA) environment. This paper explores the application of the full function point method in estimating the size of an SOA system. Based on the research on the full function point method and Business Process Modeling Notation(BPMN), the mapping rules are defined and the estimation step is given, with an example explaining the estimate process.%规模估算足项目估算的基础,然面针对面向服务体系结构(SOA)系统的规模估算没有一个有效的解决方案.为此,探讨全功能点方法在估算SOA系统规模中的应用,在研究全功能点方法及业务流程建模标记的基础上,定义全功能点上要元素和业务流程建模标记主要元素的映射规则,给出估算步骤,同时以一个实例说明估算过程.
