What will be an ideal response?
A data dictionary is a central storehouse of information about the system’s data. An analyst uses the data dictionary to collect, document, and organize specific facts about the system, including the contents of data flows, data stores, entities, and processes. The data dictionary also defines and describes all data elements and meaningful combinations of data elements. During enterprise modeling, the data dictionary documents the contents of data flows, data stores, external entities, and processes that appear in the information system's data flow diagrams.
