Open Group Architecture Framework supports four architecture domains: To memorize, remember 'Bad Tea' :)
• Business (or business process) architecture which defines the business strategy, governance, organization, and key business processes of the organization
• Applications architecture which provides a blueprint for the individual application systems to be deployed, the interactions between the application systems, and their relationships to the core business processes of the organization
• Data architecture which describes the structure of an organization's logical and physical data assets and the associated data management resources
• Technology architecture which describes the software infrastructure intended to support the deployment of core, mission-critical applications
and EA is enterprise architecture?
