PyDAO is very thin object-relational mapper similar to Hibernate (but much simpler). It's created to speed-up application development. It's very simple, but powerful, based on POPO (Plain Old Python Objects). http://aplikacja.info/PyDAO.html Main features: - can use any database that has DB-API interface (MySQLdb, psycopg tested) - can work without database at all (useful for early phases of development) - speeds up unit testing (dedicated in memory database) What is not handled: - automatic scheme generation - separate query language - automated handling of associations (replaced by filtering by foreign keys) Here's an example how to use PyDAO: class User: def __init__(self): self.id = None self.login = None self.password = None dao = pydao.InMemoryDao() # filling database user = User() user.login = "user1" user.password = "roh8OoPh" dao.save(user) # filtering based on example userSearch = User() userSearch.login = "user1" userList = dao.list(userSearch) # updating user.password = "eew8Me8g" dao.update(user) Enjoy! -- Dariusz Cieslak http://aplikacja.info - custom software systems
