The impact of patterns on services and vice versa

摘要

Design patterns are a concept which has contributed a lot to the advancement of the field of software engineering. On the other hand, the introduction of services has brought forth a new direction in software development. In this paper we try to consolidate the two concepts by showing their mutual interdependence, by analyzing the subset of middleware-services. In this context we examine how both design patterns have influenced new services and how services have led to the introduction of new patterns. Both aspects are illustrated by various examples.
