Transaction Flow Diagram
To create a transaction flow diagram, programs designed specifically to draw flowcharts are particularly well-suited to the task.
The top-down method is used for TFA. Firstly, draw the upper layer of TFD; next, draw each description function to detail the TFD.
Six Basic Transaction Flow Diagram Symbols
The normative symbols of TFD are defined as follows:
|Symbol of unit or department processing the transaction; represent someone or something involved in the transaction.|
|Symbol of flow and direction of data; represent by an arrow.|
|Symbol of flow.|
|Symbol of documents, files and forms; represent carrier of data.|
|Symbol of transaction description; generally represent by a simple imperative sentence.|
|Symbol of data storage or documents; represent another carrier of data which is stored as the archive.|

2. Clarify relations between posts or processes;
3. Remove unnecessaries; integrate equivalents, add new contents, and;
4. Determine which ones are to be processed by computer system.
