This article provides a basic foundation for developing a Service-Oriented Enterprise Architecture (SOEA) through a conceptual data architecture design. SOEA uses services (i.e. business, software and technology) and data to describe the composition of strategy, business, data and information technology. SOEA has to identify the business services and data needed to support the strategy and business processes of the enterprise, and map the business services and data to software and technology services (i.e. IT infrastructure services). This type of architectural framework supports heterogeneity, interoperability, and extensibility which serve as the basics for continued enterprise growth and effectiveness. The article also addresses the architectural constructs required to support the business goals and informational needs across an enterprise by principally addressing the service and data architecture layers providing the blueprint for the architectural design.
