Today, Kognitio announced the release of version 1 of Pablo. Pablo is basically an OLAP engine for Big Data. According to Roger LLewellyn (CEO of Kognitio), "virtual cubes can be built, populated and queried on the fly, with the minimum of time before data is ready to be examined. At the same time, by allowing users to take advantage of the familiar environment of Microsoft Excel, there is no need for extensive training before organizations can take advantage of this data. While Pablo does not immediately mean the end of physical cubes, the ability to virtualize large and complex cubes is an important leap in the evolution of OLAP."
