sybase dbo and ownerships

based on http://www.benslade.com/tech/OldIntroToSybase/security.html

Database tables, stored procedures, etc. are owned by users in a database -- regular developer accounts or special accounts. Full syntax for referring to a table, view, or stored procedure is [1]:

database.owner.object

There is a special (different from regular login accounts) user in each database called the database owner or "dbo". The dbo has all privileges within her own database. Each database has one and only one "dbo" user.

The database owner (dbo) can also own objects. In most production environments, the dbo (rather than developer users) owns the tables and stored procedures in a database. This is to preempt developer resignation (or passing away:(

[1] I think in many systems "owner" is omitted cos there's no other owner beside dbo. In other systems, for the owner the current login session's database name (??) is used as a first choice. The dbo is used as the second choice
