Think of a database table as a library shelf containing books. When you pull a book from the shelf, the self doesn't get smaller. It just contains empty slots where other books can be inserted. The reserved size of the database won't get smaller unless you shrink the data and/or log files. However, it is recommended that the DBA not shrink files, because growing files causes time, blocking, and fragmentation.
