Business model driven service architecture design for enterprise application integration

Increasingly, organisations are using Service-Oriented Architecture (SOA) as an approach to Enterprise Application Integration (EAI), which is required for the automation of business processes. This paper presents an architecture development process for guiding the transition from business models to a service-based software architecture. The process is supported by business reference models and patterns. Firstly, the business processes models are enhanced with domain model elements, application architecture elements and business-level patterns. Afterwards, business reference models and patterns are exploited to identify software services and their dependencies. The subsequent activities are focused on the transformation of the enhanced business processes to a service-based architecture that solves the application integration problem.
