Python Forum

Hy, i am wondering what is the difference between sqla wrapper and sqlalchemy in python? Why arent manny tutorials on sqla wrapper? I am starting to learn programing in python.
Second thing is, how to make relationship between tables in sqla wrapper?
I really appreciate your help ;)

I personally avoid wrappers until they have been around for at least 5 years and proven themself useful, not a hard rule, and may try something earlier if it shows widespread use.
