Publish-discover-compose paradigm of service-oriented computing (SOC) presents a challenge on service applicability. Services are not just for predefined clients, rather for potentially many unknown clients. Hence, published services should be highly adaptable to various service clients and contexts. For that, service variability must carefully be modeled(More)
Component-Based Development (CBD) is revolutionizing the process of building applications by assembling pre-built reusable components. Components should be designed more for inter-organizational reuse, rather than intra-organization reuse through domain analysis which captures the commonality of the target domain. Moreover, the minor variations within the(More)
In component-based development (CBD), component is the basic unit for reuse and it provides a relatively coarse-grained functionality. A component typically consists of several related objects, where they collaborate in order to carry out system operations. Hence it is essential in CBD to identify components with high cohesion and low coupling. In this(More)
The publish-discover-compose paradigm of service-oriented computing (SOC) presents a new challenge on the service applicability and adaptability. Services in SOC are not just for dedicated service clients, rather for a group of diverse and unknown potential service clients. Hence, service providers try to develop and publish services which can be applicable(More)
Both product line engineering (PLE) and model driven architecture (MDA) are emerging as effective paradigms for building a family of applications in cost effective way. PLE supports this by reusing common assets and MDA supports this by generating applications on diverse platforms through model transformation. However, both technologies have shortcomings to(More)
