Abstract

A system includes a database instance having a data storage system with a data store area storing first and second data partitions, where the respective data partitions each include a plurality of database pages storing respective tenant-independent/-specific data and respective first/second converters associated with the respective partitions. A database management system (DBMS) to receive a request for a database object and determine whether the database object is associated with tenant-independent data or with tenant-specific data. If the database object is associated with tenant-independent data, the DBMS determines a location of first database pages associated with the database object within the first plurality of database pages based on the first converter. Or if associated with tenant-specific data, the DBMS determines a location of second database pages associated with the database object within the second plurality of database pages based on the second converter. A method is also disclosed.
