If you were to run a booking system for say a leisure centre. What database system would be required for something of that size?

Alright thanks for the feedback. Basically the place were I work have payed for a whole new system to be put into place that will be used to book things like the Swimming pool, squash courts etc. I havn't heard all the details but I had heard the company wanted to use MSDE which if I remember correctly was only for small systems?

This company also couldnt answer any questions on backup solutions etc.
