Designing components for e-services

چکیده
Component based approaches are becoming more and more popular to support distributed application development. The concept of component itself, however, is not generally agreed upon and several definitions can be found. Moreover, different approaches to object oriented component modeling obtain different abstraction levels (conceptual vs. operational). In this paper, we discuss the concept of component in the framework of e-Service and e-Application design, where these services are based on legacy systems. We give a precise definition of stateful and stateless components, and we discuss their characteristics and their applicability in different stages of web application development.
