Database connection for Tbl_B established

I have a question regarding "connection for xxyy established" The situation
below shows records being added to 3 tables which are heavily populated. We
never "update" any table, only read from them. Or we delete a full-day worth
of records from them.

The question is: Is this method of repeatedly establishing and
re-establishing database connections with the same 3 tables efficient? As
in, is there a better way to add data?
