Static and dynamic classifications for SOA structural attributes metrics

Evaluating qualities of software based on software structural attributes such as coupling and cohesion are frequently done in practice as these attributes directly have impacts on value of higher level quality. Concerning oneself with structural attributes values early on helps developers to predict quality attributes level in the software. Service-Oriented Architecture (SOA) is an architectural concept where services are used as building blocks in developing new software. Lots of structural attributes metrics related to SOA had been proposed these recent years, which triggered an investigation to classify these metrics based on specific criteria. In this paper, we introduce classifications for SOA based structural attributes metrics, where the metrics are restricted to coupling, cohesion and complexity metrics. These metrics are classified based on software static and dynamic aspects with some brief introduction for each metric. By classifying these SOA based structural attributes metrics, it will allow user to avoid redundancy in proposing similar metrics thus increases the reusability of existing metrics.
