What is User Role Hierarchy in salesforce?

Hi Deepak,

Role hierarchy is a mechanism to control the data access to the records on a salesforce object based on the job role of a user. For example, a manager needs to have access to all the data pertaining to the employees who report to him, but the employees have no access to the data that is only owned by their manager. In this manner, the access model looks similar to the org chart in an organization but it need not be exactly same as the Org chart.

The role hierarchy automatically grants record access to users above the record owner in the hierarchy. This option is enabled for all objects by default. To change this, we take help of custom objects and manual acess grants.

Thanks.

Salesforce allows us to control the records access and organization reports using roles. In other words, you can use it to control record-level access in Salesforce. It describes how roles connect to each other. It may or may not be exactly akin to your organization hierarchy. A role can have one, more than one, or even no users assigned to it. It is best practice to ensure that every user is assigned a role when they are first added to the system.

Users who are higher in the role hierarchy will be able to see the records of people below them. Users who share the same the role or who are at the same level  cannot access each other's records:
