Comprehensive data flow diagrams ultimately show where the systems make data vulnerable. Threat modeling best practices generally consider data safest when at rest, so look to points in data flow ...

Data Flow Modeling can be done at both data source (generally meaning document) and data element (meaning specific item) levels. The picture above, for example, is a trivial diagram showing three ...

This paper presents a general model to assess the impact of data and process quality upon the outputs of multi-user information-decision systems. The data flow/data processing quality control model is ...

Moreover, data-flow modeling must be added, relationship semantics have to be clarified, and sequence diagrams need enhancing.
