What are the two components of Phase C in the ADM?

Phase C of the Architecture Development Method (ADM) within TOGAF is focused on the development of the Data Architecture and the Application Architecture. These two components are essential as they define how data is managed and utilized within the organization, as well as how applications interact with that data to support business processes.

In more detail, Data Architecture refers to the structure of an organization's logical and physical data assets and data management resources. It addresses concerns like data storage, retrieval, and security, ensuring that data aligns with business needs. Application Architecture, on the other hand, outlines the applications needed to manage data and support business functions, detailing how these applications will interact with each other and with the data they utilize.

The other choices encompass elements that might be relevant in various contexts but do not align specifically with Phase C of the ADM. For instance, Business Architecture and Technical Architecture might pertain to other phases focused on understanding business goals and technical constraints, while Architecture Vision and Governance Structures are more related to the overall framework and guidance for the architecture process. Similarly, Infrastructure Architecture and Security Architecture address different concerns more related to the implementation and operational aspects rather than the design of data and applications specifically.
