The complexity of Web services composition process is intuitively relevant to the effects such as readability, testability, reliability, and maintainability. Analyzing the complexity at all stages of process design and development helps avoid the drawbacks associated with high-complexity processes. In this paper, we present a control-flow complexity measure of the structured process of Web service...
The following short paper describes a tool supported method for measuring web service interfaces. The goal is to assess the complexity and quality of these interfaces as well as to determine their size for estimating evolution and testing effort. Besides the metrics for quantity, quality and complexity, rules are defined for ensuring maintainability. In the end a tool - WSDAudit - is described which...
Service-oriented architecture has been widely applied to construct new software system or integrate some legacy applications. Web service technology is the most representative approach to build such system. However, this new software development manner inevitably brings plague to the latter maintenance activities such as comprehension and measurement, despite its convenience for constructing software...
Due to the complexity of Service-Oriented Architecture (SOA), cost and effort estimation for SOA-based software development is more difficult than that for traditional software development. Unfortunately, there is a lack of published work about cost and effort estimation for SOA-based software. Existing cost estimation approaches are inadequate to address the complex service-oriented systems. This...
Web services technology provides a way to integrate some distributed service units over the network into a coordinative system. Compared with the traditional enterprise application integration (EAI) techniques, it provides better interoperability for data exchange and application invocation. Therefore, it has been widely adopted for constructing distributed applications. Due to code invisibility and...
Today service oriented architecture (SOA) has presented a huge of advantages such as flexibility, maintainability and integration. Therefore, many developers choose it to develop their systems. It leads to the need of evaluation of service-oriented software's quality. In this paper, we propose a suite of complexity metrics for SOA based on Web service definition language (WSDL). These metrics were...
