Optimal Granularity for Service-Oriented Systems
نویسندگان
چکیده
The improved interoperability and business agility of business systems based on Service-Oriented Architecture (SOA) has created an increased demand for the reengineering and migration of legacy software systems. The wide range of current migration techniques for legacy systems in different implementations technologies does not address important aspects of service granularity, which affect service reusability, governance, maintainability and cohesion. This paper proposes a novel framework for the effective identification of the key services in legacy code. The approach focuses on defining the right services based on standardized modelling languages (UML and BPMN). This framework provides effective guidelines for optimal service granularity for a wide range of possible service types.

متن کاملA Quantitative Measurement and Validation of Granularity in Service Oriented Architecture
The prominent principle of designing service in Service Oriented Architecture is service granularity. The granularity is a crucial design decision. The service should be neither too coarse nor too fine grained. Therefore it should be evaluated at the design phase itself to measure its level of appropriateness. This paper proposes a suite of metrics for measuring service granularity quantitative...
