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.
