Here's a simple Dbase in Access 2003 that allows you to enter an unlimited number of teams or players - will create a set of fixtures - starting from a given date - and then give you the ability to record scores and automatically calculate the League table.

As it stands everyone plays everyone else once - but additionally coding could be implemented that allowed for return or multiple matches.

Coding isn't perfect - if you create more than one league with the same players it gets confused as to what player is in what league.. but I'll let you figure out how to solve that!!
