Context Driven Approach for Enterprise Architecture Framework

Abstract

Part 4: Engineering of Enterprise Software ProductsInternational audienceDecision making process within the enterprise is complex due to unavailability of widely accepted, flexible and dynamic Enterprise Architecture Framework (EAF) that comprises of service-based applications and has strong dependency on Service Oriented Architecture (SOA). Rapidly changing business scenarios have become normal characteristics of SOA based applications and Enterprise Information System. Existing non-SOA based EAFs are lacking of flexibility, scalability, context sensitivity, re-configurability and agility. On the other hand, existing SOA-based EAFs are merely capable to handle context sensitivity, reusability and agility of Enterprise Information System. To address such issues, this paper proposes a novel SOA-based EAF, called SCORE architecture, comprised of five loosely coupled layers namely, Subject layer, Context layer, Object layer, Role layer and Essence layer. Moreover, a set of relationships are proposed for SCORE architecture to exhibits the intra-layer and inter-layer associations among the constructs of different layers. Further, the inter-layer interactions and message flows in SCORE framework are analyzed using UML notations. The proposed enterprise architecture is illustrated using a suitable case study. Finally, a comparative study is performed with the Zachman Framework [1], to exhibit the benefits of the proposed EAF in the context of Enterprise Information system

Dynamic Context Driven Re-configurable Business Process

“…A novel and unique approach is proposed in this paper to settle the above challenges. The SCORE [4,5] framework contains a number of weakly associated layers like essence, role, object, context, and subject. Among which in the subject layer the hierarchical structure of goal and its corresponding sub-goal sets are outlined by the help of a feature graph.…”
