Ex) Scanner at the register.
Data editing
Checking data for validity and completeness to detect any problems.
Quantity and cost data must be numeric
Names must be alphabetic
Codes associated with an individual transaction
are edited against a database containing valid
codes
Data correction

Should specify the problem so proper
corrections can be made.
Systems should provide error messages
that alert those responsible for editing the
data.
