BlueXML is a software publisher, specialized in providing tools for Alfresco, which aims to increase developers' productivity, solution sustainability and extend Alfresco capabilities. Developers' productivity is improved through a graphical tool which permits to design models for Alfresco, with types (classes) and processes. Models are then directly generated on the chosen version of Alfresco, increasing developers' productivity by a factor of 10. Thanks to models combined with an automatic generation process, it is easier than ever to migrate applications from one version of Alfresco to another, ensuring solution sustainability. At last, BlueXML extends Alfresco capabilities through various tools like a SQL module which permits to develop usual database applications on Alfresco.
