Firstly apologies if this has been asked before…

In the N5 arrangements we have:

Attribute size

and

Validation: field length

I understand the difference between these two and that can provide the basis for exam questions. However, on a practical level would these two always be the same in a data dictionary?

Many thanks,

Richard

Hi Richard,

I think the answer would be no – they are different things. For example, you may have a password field with a Field Size of 10, but the validation might be that the password has to be more than 6 characters. In this case, the data dictionary would have to reflect a Field Size of 10, but the validation would be

length>6

.

Hope that makes sense and helps.

Yours

Gordon
