Classification

Classification is the process of evaluating incoming user connections and assigning them to a workload group. Classification is performed by logic contained in a user-defined function. The function returns the workload group name, which Resource Governor uses to route the sessions into the appropriate workload groups.

When Resource Governor is configured, the login process for a session consists of the following steps:

1. Login authentication

2. LOGON trigger execution

3. Classification
