NriDB (Interventional Neuroradiology Database) is a client-server application which allows to manage all the interventions of a Neuroradiology Department.
It stores information about the patient, the intervention and the material used.
It generates surgical PDF reports and epidemiological statistics.
It's completely written in Java, and uses H2, a very fast and open source Java SQL database. It incorporates a license manager, allowing to manage trial licences.
