In which domain does data management primarily occur within TOGAF?

Data management primarily occurs within the Data Architecture domain in TOGAF. This domain is specifically focused on the structure, governance, and management of data within an organization. It establishes guidelines on how data should be managed, including the processes, standards, and tools required to ensure data integrity and availability.

Data Architecture encompasses various elements, such as data modeling, data storage solutions, and data security measures, which all play crucial roles in effective data management. By defining a clear and systematic framework for managing data, an organization can ensure that its data assets are aligned with its business goals and objectives.

The other domains mentioned—Application Architecture, Technology Architecture, and Business Architecture—focus on different aspects of enterprise architecture. Application Architecture deals with solutions and how they interact, Technology Architecture addresses the hardware and software technologies required, and Business Architecture focuses on business strategies and objectives. While all these domains interconnect, the Data Architecture domain is distinctly responsible for the specifics of data management.
