Architecturally, databases fall into two fundamental groups: repositories that store Oracle system data; and data sources that are the subject of analysis, presentation, and reporting.
There are two important repositories for information storage:
Common repository—Oracle system data in supported relational database tables
Shared Services—User, security, and project data that can be used across Oracle products
Relational data sources, for example, Oracle, IBM DB2, and Microsoft SQL Server
Multidimensional data sources, for example, Essbase
Oracle's Oracle applications, for example, Oracle Hyperion Financial Management and Oracle Hyperion Planning
ODBC data sources
