How and why Drupal is a perfect application framework, for business applications in particular, was presented at the #2 Drupal Café in Lübeck. This presentation covers some use cases far away from the classical CMS functionality and shows how to reuse existing modules and distributions to build flexible business applications with Drupal spending less and less time with basic features such as CRM , quotes, orders and invoices. ERPAL Platform is part of the presentation as a base distribution to build a SaaS business or fully integrated business applications.
