1. In a computer system operatively connected to a database system, a method for monitoring and analyzing database performance problems under usage of an interface to a database performance database storing performance data collected during runtime of said database in a redundancy-free form, wherein said performance data is extracted from said performance database and transformed into a problem-specific form specific for a query formulated by a database administrator for detecting a respective individual database performance problem, wherein said query uses multi-dimensional cubes and is based on a logic coupling between said redundancy-free and said problem-specific form, the method comprising: storing a problem-cube model implementing said logic coupling and comprising information on the mapping relationships between a database performance problem and a respective cube or one or more cube sets appropriate for a problem analysis of a respective performance problem; in response to detecting a specific performance problem automatically filling said cubes with respective performance data from said performance database by exploiting said implemented logic coupling; and outputting the filled cubes to an output interface usable to deploy said filled cubes for cube-based database performance analysis.
