Abstract: A system includes a relational database management system component and a column-oriented data processing component. The relational database system component stores database information in a row format. The column-oriented data processing component stores the database information in a column format. In response to a database update request, the relational database management system component updates the database information stored in the row format; the relational database management system component notifies the column-oriented data processing component of the database update request; and the column-oriented data processing component updates the database information stored in said column format. In response to a query request, the column-oriented data processing component generates a query response based on the database information stored in said column format. In this manner, the system is able to generate up-to-date reports without the need for extraction, translation and loading procedures.

Abstract: A robust tenant placement and migration system, a process, and a respective controller for database-as-a-service environments are disclosed. Multiple tenants (T) are allocated on a set of in-memory database servers (S), such that workload changes depending on the tenants' behavior are considered, while maintaining strict service level objectives. The placement and migration are based on a migration command which, in turn, is based on an interleaved placement by interleaving tenants (T) across servers.

Abstract: In one embodiment the present invention includes a relational database management system component and a column-oriented data processing component. The relational database system component stores database information in a row format. The column-oriented data processing component stores the database information in a column format. In response to a database update request, the relational database management system component updates the database information stored in the row format; the relational database management system component notifies the column-oriented data processing component of the database update request; and the column-oriented data processing component updates the database information stored in said column format. In response to a query request, the column-oriented data processing component generates a query response based on the database information stored in said column format.
