Our EPOS system (Stockade) feeds back its data to a MS SQL Server 2000 database. The EPOS software generates some reports on the data (which can be produced in various formats, including Crystal Reports), but we would like to do more powerful reports. For example, see how a particular pub (I work for a brewery) has done on Thursdays in the last year.
I'm not completely unfamiliar with databases but something straightforward and cheap (ideally free) would be great!
Perhaps it would be easier to work with the data that the reports produce (excel, CSV etc.)
