Casey, There are two ways in MarkLogic 7 to query a specific database: Create a separate app server (HTTP or XDBC) for each database. An app server has a default database that you can set in configuration. Each query/update evaluated for that app server runs against that database. Many app servers can point to one database, but an app server can only be associated with one database. Another, lower-level means is to use xdmp:eval <http://docs.marklogic.com/xdmp:eval?q=xdmp:eval> or xdmp:invoke. These allow you to specify a database at runtime and evaluate specific code against it. I wouldn't recommend this as a general approach, though. It will make your code less readable and, in certain scenarios, will prevent MarkLogic from maximizing some performance optimizations it does under the covers.
Another approach might be to create protected collections for each "tenant" within the same database. With MarkLogic's role-based security, you can be assured that you can completely restrict viewing and editing to very specific roles. You can take a similar approach to running privileged code with amps. Take a look at the Security Guide for more details <http://docs.marklogic.com/guide/admin/security#chapter>.
