I am looking for the best way to track data changes. Basically I will have some users entering data into a form but on a weekly basis I have to QA the data. What I want to be able to do is change the data but still keep the old data so the end user can see what the data is changed from and changed to.
My table has 2 fields that would require changes named Process and Cause. I would like to create 2 new fields called qaProcess and qaCause that would store the old data. The correct (or corrected) information should remain in the original Process and Cause fields for reporting purposes. What is the best way for me to move the incorrect data from one field to another. Is this the best way to go about it? Should I consider using a separate table to capture this data?
Only about 1 in 20 records would require this change.
Any help would be greatly appreciated.
