file specifications and database structure

M

Someone asked me to build up a datastructure and also denote the file
specifications. I actually don't know what is expected of me to do? My
datastructure defines sets, indices and parameters, so if I am correctly I
can create my structure by inserting relationships. But what exactly is meant
by a file specification? Is it meant that I have to say whether some input is
a number/ text/ ... or is the data type totally different from the file
specification?

Thank you very much...
