【摘要】 随着软件的复杂度越来越高,由此引起"软件危机"也就变得越来越严重。从而引发了软件复用技术的研究。构件化软件开发作为一种十分有效的软件复用技术,可以有效的缓解"软件危机"的压力。按照标准软件构件模型(COM、CORBA、EJB等)开发软件构件,对一个组织的长远发展非常有利,但是通常组织内部存在许多没有按标准软件构件模型开发的资源,如何从中发掘重用构件,却没有一个行之有效的方法,提出了一个基于工厂模式的工厂重用模型可以部分解决这个问题。更多还原

【Abstract】 As the complexity of software is becoming higher and higher,software crisis is becoming more and more serious.This causes the study of software reusability technique.Component based software development(CBSD) can relieve efficiently the pressure of software crisis as an efficient software reusability technique.It is very advantageous for the long-term interest of an organization to develop software according to the standard model such as COM,CORBA,EJB etc.But,usually,an organization has a lot of source that is developed not according to the standard model.There are not methods to get the components from those sources.There is not a well-proven method.A model is introduced based on factory pattern and can go halfway towards solving the problem.更多还原
