基于对象数据流图的可复用方案

A Reuse Approach Based on Object Data Flow Diagram

继承结构化方法的对象数据流图支持软件的系统分析、设计和程序设计诸阶段的平滑迁移。基于此软件复用方案按软件生命周期分层，包括：说明需求规格的应用层，定义用户介面的介面层，用对象数据流图进行分析、设计并导向程序设计的子系统层，实现程序设计的元件系统层。

The object data flow diagram (ODFO) inherited the structure methodology supports thetransition from system analysis to design, and the implementation in software development processes. Thispaper presents a software reuse approach based on ODFD which is the layered framework architectureincluding the application layer providing the requirement specification, the interface layer making theuser's interfaces, the subsystem layer using the ODFD to analyze and design software, and the objectcomponent system layer constructing software.
