Doc Field tracking history

I am trying to add field tracking feature to all the fields of a doctype. Just wanted to clarify one thing:

Where are the field history saved in the database. Like for example, if a lead is assigned to some other person, then this is shown on lead’s timeline. Where is this timeline data fetched from database?

Is there a configuration to put other fields on track?

I have figured out the database table in which the history is getting saved. Table name is tabCommunication.

All the logs (login , logout , assignments, document creation) are getting saved in this table.

Now if suppose I want to track change history of a docfield A, should I manually enter records into this table or is there any generic way to track field histories.

Yes, you need to write a code on change of doc field to maintain history.
