Hi iyyappan,
Process Builder:
Process Builder is a point-and-click tool that lets you easily automate if/then business processes and see a graphical representation of your process as you build.
You can use the Process Builder to perform more actions than with workflow
Process builder allows you to do the below actions which workflows cannot.
Call an apex class
Call a flow
Create a new record
Update records
Email alerts
Post to Chatter
Submit for approval
Quick Actions
Workflow:
It is a business logic that evaluates records as they are created and updated and determines if an automated action needs to occur. In a way it allows records to speak up or do something – update data, notify people or external systems.
Workflow does only 4 actions
Create Task
Update Fiel
Email Alert
Outbound Message
