SUBJECT: DATA FLOW DIAGRAMS

DATE: 04/04/98

Attached to this memorandum are the data flow diagrams and the data repository definitions.

The diagrams attached to this memorandum contain how the user's interaction and data flow through the proposed system. The first diagram begins with the processes of the complete system and each diagram thereafter decomposes the system into its smaller components. The level-0 diagram displays all modules and how the user's query passes through them. The level-1 diagram focuses on the medal module and the processes taking place as the user's query passes through it. The level-2 diagram d isplays the process in the medal module in which the user query is processed and breaks it down.

These diagrams show exactly how the proposed system will handle the data passed into it and what it returns. The data repository definitions following the diagrams reference each data flow and data file.

If there is any concern to the flow of data throughout our proposed, please contact me at[email protected].
