Differenciate between Trigger and Workflow in Salesforce?

Workflow

Workflow is automated process that fired an action based on Evaluation criteria and rule criteria.

We cannot perform DML operation on workflow

We cannot query from database

Trigger

Trigger is a piece of code that executes before or after a record is inserted or updated.

We can access the trigger across the object and related to that objects

We can use 20 DML operations in one trigger.

We can use 20 SOQL’s from data base in one trigger.

Hello.

Workflow is a point and clicks Tool which doesn’t need coding. When you want to take actions like Update filed, Email, Outbound message, and create the task from the same object or from child to the parent object(in the master-detail relationship) you can use workflow. You can also perform these action based on time triggers. It’s an automated tool which fires based on Evaluation criteria and rule criteria. Using workflow you can’t create a record.

A trigger is a programmatic approach which fires when before or after a record is inserted, updated or deleted. Using a trigger you can work on multiple objects. It involves coding you can query and you can perform any DML operation.

Thanks.
