Can I get to know how the add-ons in home assistant stores the data?

Add-ons in home assistant stores the information for example the file editor add-on stores the information of different integrations we have added in our home assistant.
For example, I have two integrations one is related to the camera integration and another one is related to the integration of a netgear device then on restarting the device how the add-on will get to know that I have made integrations of these devices?
