System Data Model

The System Data Model provides a full and detailed definition of the structure of all the data that the system is to store. This includes data identified within the Business Data Model that is within the scope of the system. It also includes additional data structures that may be required to support any functionality, within the system, which is concerned with processing that is not directly visible to the end user. These include data concerned with the system’s infrastructure and delivery mechanisms. Examples include those structures required for the control of queues and replication of data across a distributed network.

The model consists of one or more entity relationship diagrams together with full descriptions of the entities shown on the diagrams, their attributes, relationships and identifying keys.
