Variability is incorporated in component oriented software development especially in the connectors besides components, for efficient configuration of software products in this thesis. Components have been regarded as the main building blocks in the development of software, especially in component based approaches. Connectors, however, were also part of the solution but with not much of a responsibility when compared to components. When considered in a holistic approach to yield executable code starting with the commonalities and variabilities in a domain model, one can realize the importance of the connectors: A realistic integration can and should utilize connectors for the various connector responsibilities, recently studied in the literature. Thus the connector structures are proposed to take place in the component model of COSEML within the classification for their responsibilities. Assigning more responsibilities to connectors suggests the enhancement of their internal structures with respect to some configurability along variability modeling and handling the tasks expected from the connector as such classifications require. This research defines the configurable mechanisms in connectors for 1) variability management and 2) conducting the defined responsibilities that are more than merely providing a connection port. As a future result, connectors will be managed like components, having some functionality and corresponding executable code in them. A case study is presented for the demonstration of the functioning of the proposed connector.
