Data and application architecture are two of the other architecture domains defined in TOGAF. The data architecture focuses on an organization's data and how it is managed, while application architecture involves the enterprise's software applications.
The results from the architecture vision and business architecture phases are used to determine the architectural changes that will be necessary to an enterprise's data and application architectures.
As was the case with Phase B, the current and target states of the architecture are compared so as to determine the gap between the two. This allows for an architecture roadmap to be created for the candidate application and data components that will be needed to bridge the gap.
