摘要
设计模式的描述、存储和检索是实现软件复用的关键技术。目前所采用的文档描述和存储方式十分不利于设计模式的有效利用。该文提出了基于XML的设计模式描述和复用系统(DPRU),给出了系统的总体结构并对其核心部分的实现进行了论述。DPRU系统充分利用了XML对于半结构化数据的描述能力以及关系型数据库技术的存储和检索特性,可实现分布式多用户环境下的设计模式检索和复用,同时也提供了多种应用扩展。
The depiction,storage and retrieval of design pattern are very important for the software engineering practice reusing.The current document method is not suitable for the description and storage of design pattern.Based on XML ,the system of design pattern describing and reusing(DPRU)is proposed in the paper,and the general structure and realization of the kernel parts of it are showed.The DPRU system has made full use of the capacity of XML in describing the semi-structure data and the RDBMS' storage and retrieval characteristics.So that the system can be used to search and reuse the design patterns in the development of a software.Several extension application is given at the same time.
