define_tables creates the table and attempts a migration if table has changed or if database name has changed since last time. If you know you already have the table in the database and you do not want to attempt a migration add one last argument to define_table migrate=False.

This is a simple user registration form. SQLFORM takes a table and returns the corresponding entry form with validators, etc. SQLFORM.accepts is similar to FORM.accepts but, if form is validated, the corresponding insert is also performed. SQLFORM can also do update and edit if a record is passed as its second argument.
SQLTABLE instead turns a set of records (result of a select) into an HTML table with links as specified by its optional parameters.
The response.menu on top is just a variable used by the layout to make the navigation menu for all functions in this controller.
