Physical

Update of Architecture requirements at end of Physical architecture development to support creation of solution implementation work packages.

This diagram shows how data is extracted from baseline or source location(s) and loaded into target location(s). It may show where data is transformed and/or cleansed on the way. In Phase C of the ADM, the diagram is likely to be at an overview level. Later, it may be elaborated to show which source data items map to which target data items.

The purpose of the Data Dissemination diagram is to show the relationship between data entity, business service, and application components. The diagram shows how the logical entities are to be physically realized by application components. This allows effective sizing to be carried out and the IT footprint to be refined. Moreover, by assigning business value to data, an indication of the business criticality of application components can be gained. Additionally, the diagram may show data replication and application ownership of the master reference for data.

The Network and Communications diagram describes the means of communication — the method of sending and receiving information — between these assets in the Technology Architecture; insofar as the selection of package solutions in the preceding architectures put specific requirements on the communications between the applications. The Network and Communications diagram will take logical connections between client and server components and identify network boundaries and network infrastructure required to physically implement those connections.
