ESA: Enterprise Service Architecture

Abstract

The Service oriented perspective is emerging as an important view both for business architecture and IT architecture in the overall context of enterprise architectures. Many existing enterprise architecture frameworks like DODAF, MODAF and NAF have lately been extended with service-oriented views. The UPDM UML Profile and Metamodel for DODAF and MODAF has thus included various service-oriented views. This thesis proposes a new enterprise architecture framework ESA Enterprise Service Architecture. ESA is based on UPDM and is integrated with BPMN and SoaML for better process modeling and service architecture modeling. This thesis also demonstrates how ESA can be applied to EAEA (European ATM Enterprise Architecture), creating the EAESA- ESA solution for SESAR (Single European Sky ATM Research) EAEA framework. The hypothesis of this thesis is that the integration of the new specialised modeling approaches of SoaML and BPMN into UPDM will make UPDM better.
