Hi,
to get more answers you should write something about your problem.
Just saying. :)

I think you are looking for the Odoo documentation right?
https://www.odoo.com/documentation/8.0/howtos/backend.html

In the section Module structure (https://www.odoo.com/documentation/8.0/howtos/backend.html#module-structure)
you can find:

Odoo provides a mechanism to help set up a new module, odoo.py has a subcommand scaffold to create an empty module:

$ odoo.py scaffold <module name> <where to put it>

And here https://www.odoo.com/documentation/8.0/howtos/backend.html#object-relational-mapping
is how to create and tables and fields in the database.
