Technology

grade-IT is an object-oriented database tool with a web-enabled user interface. The application is accessed through a regular browser (Microsoft Internet Explorer, Firefox...). Role-based access administration is controlled by our user and content management system. grade-IT stores entered data in a SQL-based (relational) database. It is completely developed in Java and can therefore be distributed on any platform that supports Sun Java 5.

Security

grade-IT's security concept consists of four levels:

Level 1:

Level 1 authenticates the UserID and password, providing basic access protection.

Level 2:

Level 2 uses the HTTPS-protocol, securing transactions.

Level 3:

Level 3 is a concealed redirection of the data package through a pre-installed web server. Here, the accessible URIs are virtual. The actual addresses of the grade-IT utilisation systems (whose interfaces are made up of Java-Servlets) remain concealed. Two web servers operated by our User- and Content Management System, with different configurations, allow for various extensive methods of viewing grade-IT to be employed (for example, a restricted one for access via Internet, and an unrestricted one from Intranet). Our User- and Content Management System and grade-IT may be operated together on one server, or they may be physically separated.

Level 4:

Level 4 is controlled within the application through utilization of access rights assigned to each individual user.
