Modify Diagram 6, CHANGE COMPUTER RECORD, which is shown in Figure E7.11. This is an interactive, online program to change computer information. Add the following three processes. Create repository entries for each of the processes, as well as the data flow. When completed, zoom to 100 percent and change any data flow arrows that are not straight, and move data flow labels for a professional-looking graph. Print the diagram using landscape orientation.

a. Process 6.6, VALIDATE CHANGES. This process edits each change field for validity. The input is the KEYED CHANGES. The output fields are CHANGE ERRORS (interface flow) and VALID CHANGES (to process 6.7).

b. Process 6.7, CONFIRM CHANGES. This process is a visual confirmation of the changes. The operator has a chance to reject the changes or accept them. Input is the VALID CHANGES. The output fields are REJECTED CHANGES (interface flow) and CONFIRMED CHANGES (to process 6.8).

c. Process 6.8, REWRITE COMPUTER MASTER. This process rewrites the COMPUTER MASTER record with the changes on the record. Input is the CONFIRMED CHANGES. Output flow is the COMPUTER MASTER record, to the COMPUTER MASTER data store.
