Alfresco Software
Alfresco is a free/libre enterprise content management system for Microsoft Windows and Unix-like operating systems. Alfresco comes in three flavors:
1.Alfresco Community Edition is free software, LGPL 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.
2.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.
3.Alfresco Cloud Edition (Alfresco in the cloud) is the SaaS version of Alfresco.
Alfresco includes a content repository, an out-of-the-box, web-based user interface for managing and using standard portal content, a CIFS interface that provides file system compatibility on Microsoft Windows and Unix-like operating systems, Lucene and Solr indexing, and Activiti workflow. The Alfresco system is developed using Java technology.
