Abstract

A system, a method, and a computer program product for providing transparent access to multi-temperature data are disclosed. A query for accessing data is received. The query includes at least one selection parameter for retrieval of data. The data is stored in a plurality of partitions of a database system. Each partition has a maximum data value per column, a minimum data value per column, and a predetermined date associated with the data contained in the partition. A determination is made whether at least one selection parameter is greater than the minimum data value per column and less than the maximum data value per column. The queried data is retrieved from the partition using the predetermined date associated with the data contained in the partition.
