Abstract: A component is selected based on the function it provides in component-based software engineering (CBSE). Many techniques have been proposed for component selection under varied situations to select the optimal component from component set of same functionality. This paper proposes architecture for component selection after going through a brief survey of the component selection techniques. Here, architecture is divided into four tiers namely client requirements and system analysis tier, query and decision tier, application logic tier with clustering and component cluster tier. The current selection techniques using clustering suffers from major demerits of specifying the number of clusters beforehand and the selection process depending on subjective judgement of application administrators. The proposed architecture will be better as the need for apriori declaration of clusters will be eliminated and the cluster validation is performed to check the correctness of the clusters. This architecture is validated on a case study of set of sorting and searching components.
