摘要
A method/system considers the phenomenon of slowly changing dimensions in the process of reporting on facts of a collection of facts organized as, or otherwise accessible according to, a dimensionally-modeled fact collection. A report query specifies a temporal mode, and the specified temporal mode is processed to determine a time extent descriptor (e.g., in view of at least one of a context, in which the report query is made, and at least one dimension coordinate constraint). A processed result of querying the dimensionally-modeled fact collection includes appropriate indications of dimension coordinates in view of the time information from the time extent descriptor.
