Information Flows

DMC Data Sub-Architecture

D-2: Information Exchange Matrix

The Information Exchange Matrix describes the attributes of data exchanged between systems, including size, physical specifications for the storage media, timeliness of the data and data retention policy, as well as security classifications and other attributes.  As an alternative, these attributes may be included in artifact D-1 and eliminate the need for a separate Information Exchange Matrix.

D-3: Object State Transition Diagram

The Object State Transition Diagram will use UML methodologies to show the lifecycle of various data objects.  Further, this diagram will show entry points, as well as changes and transitions of data elements and attributes resulting from system events or triggers.

D-4: Object Event Trace Diagram

The Object Event Trace Diagram traces actions and sequencing of events thru a set of operational scenarios.  This artifact will only be produced if business rules define the scenarios and requirements for this diagram.

D-5:  Logical Data Model

The Logical Data Model will use UML methodology to produce a class diagram showing the static relationships of the data objects and the logical flow of the data.  UML is chosen for consistency in modeling the data and information artifacts.
