What is the difference between a transaction manager and a database manager?

Question

Reading on both seems like they both have a similar responsibility for managing sharing and integrity of resources, as well as for priority of execution, but I can’t find how they differ from each other? Can someone clarify this misunderstanding. Thank you.
