There is also a module in the App Store called “Audit Trail” maybe this helps you.
Create one attribute as CreatedBy in the respected entity, where ever the data updation / creation flows are there onClick of save or submit action, just retrieve the current logged in user and map this value for CreatedBy. And track this information from db.
It is built-in. In your Domain Model open an entity and check the boxes you want “Store ChangedBy” for example.
