Domain, Enterprise Technical Architecture


The Enterprise Technical Architecture (ETA) is typically divided into logical groups of related technologies and components, referred to as "domains". The purpose of a Domain Architecture is to provide a combination of domain principles, best practices, reusable methods, products, and configurations that represent "reusable building blocks". Thus, the Domain Architecture provides the technical components within the Enterprise Architecture that enable the business strategies and functions. Note, the Conceptual Architecture serves as the foundation for the Domain Architectures and ensures that they are aligned and compatible with one another.
