Answer / Solution
Answer / Solution
Data Flow diagrams are a means of representing a system at any level of detail with a graphic network of symbols showing data flows, data stores, data processes, and data sources/destinations.
The purpose of data flow diagrams is to provide a semantic bridge between users and systems developers. The diagrams are:
- Graphical - Eliminating thousands of words;
- Logical representations - Modeling WHAT a system does, rather than physical models showing HOW it does it
- Hierarchical - showing systems at any level of detail; and
- Jargonless - allowing user understanding and reviewing.
