Both process dependency diagrams and logical data flow diagrams reflect their interaction with similar symbols. For process dependency diagrams, the connectors are referred to as information views. For logical data flow diagrams, the connecting symbols are referred to as data flows and data stores.
Developing process dependency diagrams
Information views are described and named to correspond with the dependencies existing among the elementary processes in the dependency diagrams.
Now formally document each information view. Assign each information view a unique, consistent name, and describe its contents in terms of entity types, attribute types or other information views.
Views of globally available data, not included in the information views which are imported for the elementary process, are also documented (although corresponding dependencies cannot appear on a dependency diagram). These views represent the "expected effects" on the pool of information (data model) the elementary process will have.

Developing logical data flow diagrams
¤ Add data flows to reflect the dependency of elementary processes upon other elementary processes for data or resources.
¤ Add data stores where appropriate to reflect the "storage" of data in a different time frame than when it is to be utilized by an elementary process.
