Torsten, Please explain the environment you are planning to use - Operating System, whether you have full control of the machine that runs the database, how many users?.
If you are using Windows and if your needs are simple, you can use Access as it has some simple access control that can be setup. Also, the part about "database would store all its data in a file" is not very clear. Are you wanting to use a flat-file database and also have security implemented in it? If you are on linux/*BSD machine, consider using a real database. Fine access control can be implemented in your application (e.g. only the creator of a record and his/her superiors can edit it, all others view it) Please send more details to receive useful recommendations.
