I've done some relational database work in the past, but always found it quite taxing and have found myself in need of making a database once again.
The database is for a childrens nursery school and I think I've got a basis for it, but I can't work out how I would automate calculation of bills. A session can be either a morning, afternoon or full day.
I'm using LibreOffice Base to make it, and any help would be greatly appreciated!
Here's what I have so far.
