Micro and macro workflow variability design techniques of component

摘要

Components should provide variability in satisfying a variety of domains [C. Szyperski, Component Software: Beyond Object-Oriented Programming, Addison-Wesley, 2002.], but it is not easy to develop components which can be applied to all domains. Although components are developed by analyzing many different requirements, developing components that satisfy all requirements is difficult since unexpected requirements occur during the utilization of components. Hence, providing the variability of components becomes an important prerequisite for a successful component-based application development. In this paper, we propose a variability design technique that can satisfy the business workflow requirements of many different kinds of domains. The technique addresses a method for designing the variability of the workflow in a more detailed method and uses an object-oriented mechanism and design patterns. One of the most important goals of this technique is to provide a practical process can be effectively applied in component-based application development.
