Main Description |
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 system ownership of the master reference for data. In this
instance, it can show two copies and the master-copy relationship between them. This diagram can include services; that
is, services encapsulate data and they reside in an application, or services that reside on an application and access
data encapsulated within the application.
