Except the fact that database is a part of information system, what are differences between information system and database system?

Can you tell it? I googled I didn't find. Maybe you guys can help me.

There are perhaps more differences, but I'd emphasize this:

Database systems are tools for storing and retrieval of information, while information systems also include processes of collecting and delivering information to the databases, and analysis and usage of the information retrieved from the databases.

Also, while database is a part of information system, information system does not necessarily include a database.
