The product documentation of SAP Convergent Charging 2021 includes the following database references depending on your technical and business requirements and your IT strategy:
All these specialized documents relate to SAP CC Core Database, the back-end database of SAP CC Core Server.
SAP Convergent Charging supports several database technologies and suppliers. Some features and capabilities of SAP CC require specialized technology, edition, version, or license of the RDBMS in your SAP system landscape.
Refer to the SAP CC 2021 Product Availability Matrix (PAM) in PAM for more information about the available RDBMS products, versions, and options.
SAP CC Core Database is a back-end database of SAP CC Core Server, the main component of the SAP Convergent Charging software product that SAP delivers for your industries.
SAP CC Core Database contains the different data related to the business objects handled by SAP CC Core Server, such as master data (pricing catalogs of digital services and customer master data like provider contracts with allowances), business and custom data, business processing data and some technical data of SAP Convergent Charging. To ensure performances, the SAP CC Core Server system needs to perform a huge number of connections and transactions (with low latency) to this database. As a consequence, SAP highly recommends that you configure the Core database as an On-Line Transaction Processing (OLTP) database to execute real-time processes.
Recommendation
Refer to the SAP CC 2021 Application Help for more information about the system landscape architecture and the deployments of SAP Convergent Charging.

The default edition of the Oracle RDBMS and Microsoft SQL Server RDBMS is named Standard Edition, and is suited for small and medium sized businesses. Depending on your business requirements, this edition may be inadequate because of limitations related to hardware platforms. Consider performances, high-volume data, and high-availability (HA) environments.
SAP Convergent Charging defines some reserved spaces on one or multiple disks where the database systems store data objects like database tables and database indexes. This optimizes the storage of data in the database systems of the Core Database.
This concept has different names depending on the RDBMS technology:
You create these reserved storage spaces and define a maximum size, an initial size and other options like the minimum size of each subelement into a tablespace or a filegroup.
Refer to the Installation Information for SAP Convergent Charging 2021.
SAP Convergent Charging provides advanced functions to ensure the highest level of performance (high volume, very high end-to-end throughput and latency) and high availability.
These functions require database partitioning to improve the database performance with large and very large databases.
Refer to the SAP CC 2021 Tuning and System Configuration Guide and Sizing Guidelines for SAP Convergent Charging to determine when the database partitioning applies to your business requirements.
Note
SAP CC provides some specialized SQL scripts to setup the database schema with partitions in your database systems. You select these scripts during the installation of the SAP CC system. The SAP installer (SL Common GUI) enables you to tick the option 'Use partitioning' when you set up its installation parameters. Refer to the Installation Information for SAP Convergent Charging 2021.
