dbcc checkcatalog checks for consistency within and between the system tables in a database. For example, it verifies that:
Every type in syscolumns has a matching entry in systypes.
Every table and view in sysobjects has at least one column in syscolumns.
sysindexes is consistent, and fixes any errors
For each row in syspartitions, there is a matching row in sysegments.
The last checkpoint in syslogs is valid.
It also lists the segments defined for use by the database and fixes any errors it finds.
If you do not specify a database name, dbcc checkcatalog checks the current database.
