[Year 12 IT Apps] database convention - postcodes as a text field in databases

[Watson, Donald R]

Hello All,

The link below pretty much says it all.

The convention is that postcodes should defined and be input as text.
Of course there could be circumstances in which a specialised database might need to use some 'regional intelligence' based on a postcode.

A mail drop to all postcodes between 3850 and 3860 covers my area of Gippsland for example. It saves time on listing 100's of towns in a complicated case or nested if statement.
