Glossary:Central Storage Systems
The Central Storage Systems are composed of:
- The billing domain (BD) which stores CDRs and IPDRs for charging purposes; data will be stored here after a successful charging record generation procedure.
- Customer databases containing information about users, which can add extra value to CDRs or IPDRs data – e.g., socio-demographics and place of residence (where applicable);
- Data warehouses hosting collections of data from different sources; they might however not always be easily accessible due to the huge amount of data stored there.
Databases in the billing domain are generally considered most easily accessible. Data stored in the BD are collected by a so-called mediation system from different network entities responsible for providing various types of services.
