Which architecture type focuses primarily on data flow and data structure?

Data Architecture is the correct answer because it specifically addresses the organization, management, and flow of data in an enterprise. This discipline involves defining the structure, storage, and integration of data, which directly influences how data is processed and utilized across various systems and applications. The primary focus is on ensuring that data is accessible, accurate, and appropriately protected, while also facilitating seamless data flow within and between systems.

In the context of TOGAF, Data Architecture encompasses the modeling of data structures, data management policies, and the overall data governance framework, making it crucial for designing an application or system that efficiently handles data.

The other architecture types—Business Architecture, Applications Architecture, and Technology Architecture—do not primarily center on data flow and structure. Business Architecture focuses on the business strategy, governance, organization, and key business processes. Applications Architecture concerns itself with how applications are designed and interact with each other and with users but does not primarily deal with data flow. Technology Architecture looks at the hardware and software infrastructure but does not focus on data specifics. Thus, Data Architecture is the clear focus when it comes to understanding how data flows and is structured within an organization.
