I am in the planning process of a hotel booking system and have some questions about database to use.

What will be the best database to use. There will be a multi-user environment of maybe 5 to 10 users. I guess SQL server is out due to the price. How about ms access? Or SqlExpress?

We do not want a database that we need to pay for so access is a good choice. If we got it correct do we need to install SqlExpress in all computers that is running the software, Correct? Or is it ok to just install it on the computer that is having the database, Or?

Please help us to guide us in to the right direction.
