A system includes reception of an instruction to evaluate homogeneity of a first set of values of a plurality of stored sets of values, determination of a first minimum of the first set of values, determination of a first maximum of the first set of values, determination of whether the first minimum and the first maximum are equal, and if it is determined that the first minimum and the first maximum are equal, return of a value equal to the first minimum and the first maximum in response to the instruction.

Homogeneity evaluation of datasets

Embodiments provide a multi-buffering system in an application layer to support unified read/write access to different data source types of an underlying database layer. In a particular embodiment, the database layer comprises both a multi-dimensional data source (e.g. a cube), and another data source type (e.g. a Data Store Object&#x2014;DSO). An abstract buffer component of the multi-buffering system is specialized into a delta buffer configured to read/write data of the cube, and into an after image buffer configured to read/write data of the DSO. A storage mechanism component of the multi-buffering system is specialized into a cache store configured to read/write data of the cube, and a calculation scenario store configured to read/write data of the DSO. The after image buffer may support certain aggregation rules during a DSO read/write operation. The calculation scenario store may leverage capabilities of an in memory database during a DSO read/write operation.

Multi-buffering system supporting read/write access to different data source type

An InfoSet API calls a query, the call defining selections for data retrieval. These selections are passed by the query to a report, which obtains data responsive to the selections via a data source. The obtained data is persisted in a global memory which allows such data to be accessed in multiple sessions. The persisted data is retrieved from the global memory by the query which in turns provides such data in response to the InfoSet API call. Techniques for automatically creating aspects of Infosets are also described as well as other related techniques, apparatus, systems, and articles.
