sync the 2 tables for certain rows

sync the 2 tables for certain rows

This is a question of is it possible and should i try to do it?
i have two rows in my table one named jobs and one named contacts (hope
you still with me)
in jobs i have the following columns
typeofjob
id
name
phone
address
budget
due
in contacts i have the following columns
id
name
phone
address
is there a way to sync the 2 tables for certain rows?
id
name
phone
address
i ask as this would make life a lot easier for me but worried as id might
conflict
and what happens if i delete a user from contacts i would only want it
deleted from that row
i am very new to this and learning so if you can answer me with simplify
answers that be great just treat it like your trying to explain this to
your nan or something, but on the other hand she might pick this up faster
than i am :)
