This section describes how to create new users and grant permissions and authorities to them. For most databases, the bulk of permission management should be performed using groups, rather than by assigning permissions to individual users one at a time. However, as a group is simply a user ID with special properties, you should read and understand this section before moving on to the discussion of managing groups.
Even if there are no security concerns regarding a multi-user database, there are good reasons for setting up an individual user ID for each user. In addition to granting permissions to individual users, you can also grant permissions to groups of users. The administrative overhead is very low if a group with the appropriate permissions is set up.
You may want to use individual user IDs since:
The Log Translation utility (dblog) can selectively extract the changes made by individual users from a transaction log. This is very useful when troubleshooting or piecing together what happened if data is incorrect.
Sybase Central displays much more useful information so you can tell which connections belong to which users.
Row locking messages (with the blocking option set to Off) are more informative.
