ITPEC FE Morning April 2018 Question 24
ITPEC FE Morning April 2018 — Question 24 of 80
Logical check (input validation) — verify that Order date is a business day ≤ entering date.
A logical check validates that data makes sense according to business rules, not just format.
Examples of each check type:
- Format check — is the date in YYYY-MM-DD format? Are digits where expected?
- Duplication check — does this form number already exist?
- Sequence check — are form numbers in ascending order?
- Logical check — is the date a real business day? Is it not in the future?
Why (d):
- "Order date is on a business day" → business rule validation
- "Equal to or prior to entering date" → cross-field logic (date ≤ today)
- Both are logical validity checks, not format or sequence
Why not others:
- (a) Sequence check — checks ordering of records, not date validity
- (b) Duplication check — checks for duplicate entries
- (c) Format check — checks data type/pattern, not whether the value is logically valid
