As far as I know, the number in brackets eg int(11) is only used for 
numeric fields when you are importing from a fixed-width text file, with 
'load data infile'. In this case, the width of the fields is taken from 
the number in brackets from the table definition. Pretty strange stuff 
if you ask me. Anyway you can safely ignore it if you're not importing 
data from a fixed-width file. For more info see 'load data infile'.

The backticks are there to aid MySQL in parsing the string later in case 
you have used reserved words or strange characters.
