Administering SQL Server 2008

Database Owner (dbo)
The dbo is a user that has implied permissions to perform all activities in the database. Any member of the sysadmin fixed server role who uses a database is mapped to the special user inside each database called dbo. Also, any object created by any member of the sysadmin fixed server role belongs to dbo automatically.
For example, if user Andrew is a member of the sysadmin fixed server role and creates a table T1, T1 belongs to dbo and is qualified as dbo.T1, not as Andrew.T1. Conversely, if Andrew is not a member of the sysadmin fixed server role but is a member only of the db_owner fixed database role and creates a table T1, T1 belongs to Andrew and is qualified as Andrew.T1. The table belongs to Andrew because he did not qualify the table as dbo.T1.
