At the Forge - Database Modeling with Django

Let Django and its object-relational model do the SQL database work for you.

You can try all of these database queries for yourself using Django's shell:

python shell

Using the Django shell, as opposed to the straight interactive Python interface, ensures that Django-related classes and paths are preloaded, making it possible to query and modify the database from within Python interactively. This is a good way to experiment with new code that you are thinking of adding to a view method, without having to place it in a file.


Django provides a high-level interface for the definition of database models using Python, rather than SQL. This high-level API permeates the framework, making it possible to work exclusively in Python. Moreover, the API includes many convenience functions and data types that make it relatively natural to work in this way. Creating database-backed Web applications with Django is dramatically easier and better than with most frameworks I've used, although it is similar in style to Ruby on Rails. Whether you should use Django or Rails is a matter of personal taste and also depends on what others in your organization are using, but there's no doubt that if you're a Python Web/database hacker, Django is worth a very serious look.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
