Abstract

An Overview of Software Engineering Approaches to Service Oriented Architectures in Various Fields

“…The framework is a combination of five main phases: information elicitation, service identification, service definition, service realization, and roadmap and planning. The framework encompasses methods and techniques used to identify and model services and also to find services granularity [23].…”

A Genetic Algorithm to Find the Adequate Granularity for Service Interfaces

“…Choosing the adequate granularity of a service is a relevant task and a widely discussed topic [9], [4], [16], [8], [15].…”

“…One of the key factors for deploying successful services is assuring an adequate level of granularity [9], [4], [16], [8], [15]. The choice of how operations should be exposed through a service interface can have an impact on both performance and reusability [9], [16].…”

“…In literature several studies have investigated the impact of granularity (e.g., [9], [4], [16], [8], [15]), have classified the different levels of granularity (e.g., [8]), and have proposed metrics to measure them (e.g., [13], [3]). However, to the best of our knowledge, there are no studies proposing techniques to assist service providers in finding the right granularity and adopting the CDC pattern.…”

A Model-Driven Architecture Approach to the Efficient Identification of Services on Service-Oriented Enterprise Architecture

“…It will be also used (along with a proposed metric) in identifying the 'right' services with optimal granularity. The closest service type classification in the literature to that in our approach identifies eight generic service types from a hierarchical perspective [20,21]. In contrast, our classification focus is on defining the purpose of the service, i.e.…”
