Workflow Components available in salesforce?

Hello,

Workflow consists of the following components:
– Workflow Rules – trigger criteria for performing various workflow actions
– Workflow Tasks – the action that assigns a task to a targeted user
– Workflow Email Alerts – the action that sends an email to targeted recipients
– Workflow Field Updates – the action that updates the value of a field automatically
– Workflow Outbound Messages – the action that sends a secure configurable API message (in XML format) to a designated listener (not covered in this class)

Thanks.
