I new to this. I read that if you can, try to avoid many to many
relation on your tables. I also read that you can create a "Junction
Table" OR "resolver table" to dissabiguate that. My question I think
it's easy for you guys. I have a table city to city so all to all
basically. I try to reduce this relation to one to many (recomended)
but I have been unable to find clear information on the web, maybe I am
not searching for the rights keywords. Could you point me to any
resources to learn ...
