When ordering data is entered in the format shown below, which of the following is the appropriate method for checking whether the order date is a business day that is the same as or prior to the entering date?

Ordering data

Form number(Characters)Order date(Characters)Product code(Characters)Quantity(Number)Customer code(Characters)

Explanation

Logical check — it tests whether a value makes sense against a rule or another value, here that the order date is a business day no later than the entering date.

Comparing the order date with the entering date and with a calendar of business days goes beyond the shape of the field: a date can be perfectly formatted and still fall on a holiday or after today. Checks for consistency with business rules, other fields or reality are logical checks.

Answer (c)

Why not others:

  • •(a) Duplication check — detects the same data entered twice, for example a repeated form number
  • •(b) Format check — verifies the form of the value, such as a date having the right number and kind of characters, not whether the date is plausible
  • •(d) Sequence check — verifies that records or keys come in the expected order, such as ascending form numbers

Key rule: Format check asks whether a value looks right, logical check whether it makes sense, sequence check whether it is in order, and duplication check whether it is unique.
