Profiling of Web Services to Measure and Verify their Non-Functional Properties

Abstract

The following chapter focuses on the problem of the proper definition of non-functional properties and methods that may be applied in order to estimate their values. First of all, a reader is familiarized with the concept of non-functional properties and different views on the quality of Web services. Then, selected approaches to obtain values of nonfunctional properties are presented. The focus of attention is Web services profiling that seems to be one of the most promising methods to perform this task. The framework presented in this chapter was implemented and tested within the EU Adaptive Services Grid project.
