Drupal is the most popular Open Source software for content management.  On the other hand, Alresco is a top Open Source alternative for Document management.  Although, both have features that can make them interchangeable in some scenarios, but their combination can be very powerful.

A little more on Alfresco for the uninitiated.

Alfresco is a free/libre enterprise content management system for Microsoft Windows and Unix-like operating systems. Alfresco comes in three flavors:

• Alfresco Community Edition is free software, LGPL^[2] licensed open source and open standards. It has some important limitations in terms of scalability and availability, since the clustering feature has been removed from the community repository and is only available in the enterprise edition.^[3]
• Alfresco Enterprise Edition is commercially & proprietary licensed open source, open standards and enterprise scale. Its design is geared towards users who require a high degree of modularity and scalable performance.
• Alfresco Cloud Edition (Alfresco in the cloud) is the SaaS version of Alfresco.

I found a video on how to integrated both these applications and create a strong Document-Content Management platform for your company.
