The prototype Ediflow is platform for data-intensive visual analytics, such as user-dataset interactions in scientific applications. The prototype is a result of the Ediflow Digiteo DIM project (2008-2011), a collaboration between Ioana Manolescu (Inria Gemo and LRI IASI team), Véronique Benzaken (LRI BD team), and Jean-Daniel Fekete (Inria AVIZ). The platform is built in Java, and it has been deployed on top of the Oracle database management system. It integrates visualization and computation units.
