Components
OSB is a suite of batch, GUI and WEB and utility applications running on Unix against an Oracle database server.
The core of the system is the object-oriented library which provides the functionality needed by the applications.
The WEB applications are run by Tomcat and rely on CORBA servers to maintain the data in the database.

| conversion | Convert usage records as provided by the network into generic CDRs (Call Detail Record, OSB internal ASN.1 format). |
| correlation | Assemble partial usage records or correlate records from one or several network elements into one OSB CDR. |
| rating | Rate the usage records for each party that was involved in the network usage. |
| storage | Store the rated CDR into the database. |
| billing | Generate invoices in XML format for the rated network usage. |
| request server | Centralized processing of contract status changes and provisioning of subscriptions to the network. |
