Oracle database server
All data of the grid model and of the configuration metamodel are based in an Oracle database.
One or more Certa servers, connected to the Oracle database, have the grid model in their memory and run the system’s modules.
Desktops and tablets
Geographic or topological inquiries from the system’s modules are answered by Certa Servers without needing to access the database. Only the changes in the model and the inquiries on related data impact on the database.
