Zorluk: ZorComputerized Data Processing and Business Records Management

An online wholesale enterprise requires all customer purchase orders entered into its computerized database to contain a valid ten-digit tax identification number before the invoice can be generated. If an operator enters fewer than ten digits, the system rejects the entry immediately. Which computerized data processing control is being demonstrated?

  1. Input validation controlCevap
  2. B
    Output verification control
  3. C
    File maintenance control
  4. D
    Data transformation control

Cevap

Input validation control
Input validation controls consist of automated checks (such as length checks, range checks, and format checks) applied at the input stage of computerized data processing. By rejecting incomplete tax identification numbers at entry, the system prevents inaccurate or corrupt data from being processed into business records.

Adım Adım Çözüm

1
Analyze the timing and stage of the automated system activity in the scenario.
The system check occurs during data entry before processing or invoice generation takes place.
Controls positioned prior to file processing represent input-level controls.
2
Identify the purpose of checking digit length before accepting data entry.
The rule verifies that entered data conforms to required formatting constraints (ten digits).
Checks designed to detect missing, incomplete, or malformed data before acceptance are classified as input validation checks.
