Evaluation of Quality of Design for Document-Centric Software Services [chapter]

George Feuerlicht
2013 Lecture Notes in Computer Science  
Recent research efforts include attempts to develop reliable metrics for assessing design quality of service-oriented applications.  ...  Service design has been the subject of intense research interest for almost a decade and there is a wide agreement about the key service design principles that promote maintainability of software services  ...  The rationale for the metric is that maintenance effort required to accommodate new requirements can be estimated based on the level of overlap (lack of orthogonality) of message schemas; i.e. schemas  ...
