Understanding Apex Managed Sharing

Sharing is the act of granting a user or group of users permission to perform a set of actions on a record or set of records. Sharing access can be granted using the Salesforce user interface and Lightning Platform, or programmatically using Apex.

For more information on sharing, see Set Your Internal Organization-Wide Sharing Defaults in the Salesforce online help.
