Drupal Commerce is the new way to do e-commerce on Drupal 7. It's a new implementation of e-commerce solutions that takes advantage of the awesome new Drupal 7 APIs, enforcing a clean separation of the Commerce API from the default UI, and using a strict set of development standards.
Drupal Commerce provides default pre-configured installation profiles that enable new users to quickly get an e-commerce site up and running, also its test coverage ensures the code quality and stability.
Core features like Products and Orders take full advantage of D7's core Entity and Field systems. The modules leverage the popular Views and Rules modules to provide easily customizable user interfaces and order workflow automation.
See the new features of Drupal Commerce in this session, which will include a demo of the common administrations tasks and new features and also a look inside the gears of the system.
