Determine SQL Server memory use by database and object

For many people, the way that SQL Server uses memory can be a bit of an enigma. A large percentage of the memory your SQL Server instance utilizes is consumed by buffer pool (essentially, data). Without a lot of digging, it can be hard to tell which of your databases consume the most buffer pool memory, and even more so, which objects within those databases. This information can be quite useful, for example, if you are considering an application change to split your database across multiple servers, or trying to identify databases that are candidates for consolidation.

In addition to these tools, SQL Server 2008 offers extended events ("XEvents"), which you can use as a powerful tracing system. By default, the "system_health" extended events session is always on, and can provide you help to locate the source of trouble much faster.
