SQLObject is a Python object-relational mapper between a SQL database and Python objects. It is experiencing community popularity, and forms a part of many applications (e.g., TurboGears ). It is very similar to Ruby on Rails ' ActiveRecord in operation in that it uses class definitions to form table schemas, and utilizes the language's ...

A powerful ORM that allows the mapping of Python classes to database tables.
Gadfly will not allow a start up the same connection twice, however. The first "import gadfly" reads in and initializes some rather large data structures used for parsing SQL, and thus may take longer than other module imports. Within the database the user can create tables, populate them, and commit the result when they are happy:

Unlike the method on the database connection, the method on the wrapper may not actually close the database connection, but instead return it to the pool. The application need not be aware of the connection ...

What was missing was the SQL parser that could convert those calls from their text form into the C-interface used in Jet.
