well, Elmobram hasn't really set any relationships and there are a couple of lookup tables which could be simplified as they stand at the moment (tblCcoRole and tblHouse).
I also can't see the relationship between some of the tables, but given this is a cut down db and the OP says 'I did this database when I was learning so I know the data isn't the way it should be' I'm not surprised.
tblResMed should perhaps be broken down into two tables....
I can't see any fields called 'name' although use of spaces in field names and a lack of consistency in naming conventions makes for more work. Similarly, using the dreaded lookup in table design and possibly wrong data types (e.g. text fields holding numeric values) could create problems further down the line.
So I think my answer has to be that without knowing the full business process, I don't think it is for me to say.
What problems do you see?
