4 Validation is checking that data entered is reasonable.
[1 mark]
5 [1 mark for true or false and one for each reason:]
True
A range check could be used to validate
the title of the book
A length check could be used to check the
number of characters entered in the ISBN
✔
A consistency check could be used with
the Price and Author fields
A check digit could be added to the ISBN
field
A length check could be used with the
Price field
Photocopying prohibited
Reason
A range check can only be used on a numeric data
type and the title of the book has an alphanumeric
data type.
All modern ISBNs have 13 digits (ignoring the
4 – symbols) so a maximum field length of 17
characters would reduce the storage capacity
required for the database.
✔
A limit check could be used for the Price
field
A format check could be used with the
ISBN field
False
[14 marks]
✔
The price field will have 2 limits, one being >=0
and a maximum price for a book, therefore a range
check would test this whereas a limit check would
only change 1 of the 2 ends of the range.
✔
There is no direct relationship between the Price
and Author fields so consistency check would be
inappropriate.
✔
The ISBN field already contains a check digit so this
would not be required.
This field contains 13 numeric characters spaced
with 4 hyphens and these are consistent through
most ISBNs (older ones have 10 numeric characters)
so a format check is appropriate.
✔
✔
The book price field has a numeric data type
(probably with a currency sub-type) and length
checks are only applied to alphanumeric fields.
