Simple object-relational mapper for Python and PostgreSQL
This ORM uses a very minimalistic approach. The general idea is that the database schema is defined elsewhere (writing the SQL directly, or using some specialized software), and all the transactions are implemented either as methods in sub-classes of “Database”, or as stored procedures.
This ORM allows you to very easily: (1) implement complex database transactions, (2) call stored procedures, (3) do simple queries. For complex queries you should use database views and stored procedures that return tables.
