| Although the undesirable feature interaction problem has been first studied in the telecommunication domain, it is nothing new in the component-based systems and service-oriented systems beyond telecommunication. With the rapid evolution of Web services, this problem also becomes increasingly inevitable and critical in Web service composition. In this thesis, first, a classification for a collection of undesirable feature interactions in the Web service domain will be presented by causes and three nature dimensions: type, scope and role. It may help us to distinguish whether a particular approach for managing the undesirable feature interaction has been addressed in this domain. Then a detection approach will be presented for detecting feature interactions at the requirements stage in this domain with the combination of Goal-oriented Requirement Language (GRL) and Use Case Maps (UCM), which are respectively for non-functional requirements and scenarios. This approach is based on goal-oriented analysis, which allows us to reason about feature interactions in terms of goal conflicts. An e-store system will serve as a case study for giving a re-examination about the classification and how the detection methodology will work. It also will prove the existence of the feature interaction problem in the Web service domain. |
