To interpret string attributes, each named element defined by the developer in the data flow diagram (DFD) is compared with the values contained in the MultiMap.
However, the SEM also includes all associated business rules, functional requirements, technical requirements (e.g., security and data control issues, data integrity aspects, efficiency factors, performance requirements and usability concerns), system outputs, test cases, data flow diagrams, a data dictionary, data object models, data relationship diagrams and an events inventory.
For demonstration, a set of self-asking questions deriving from the three cognitive principles were designed to help specify information requirements by Data Flow Diagram.
Specifications and designs might include narrative descriptions of the program requirements and structure, graphical models of the system (such as data flow diagrams), and process specs for the modules in your system.
Data Flow Diagrams showing Context Level, Overview Level and one Overview Process decomposed down to level three;
While the concept of a table is an easy one, the question remains how one creates the table to communicate the same information and relationships as the data flow diagram. Clearly there must be ways for enumerating external entities, processes and data stores.
The new software adds flowcharts, general enhancements to all diagram types and scriptable reports, advanced data flow diagram features and the ability for large projects to use multiple data dictionaries.
