database to use for Automated Teller Machine I have been working on an Automated Teller Machine project using Visual Studio and C# for my Bachelors Degree project.

Which database platform should I use for this?  I'm considering MySQL, but am open to other suggestions.
For projects using Visual Studio, I'd almost invariably recommend using SQL Server Express.  The product is free to use, as long as you can live with the limitations: Microsoft SQL Server Express supports 1 physical processor, 1 GB memory, and 10 GB relational storage.  I'd expect for an ATM project you won't be locally storing a lot of data, so that shouldn't be a concern.
