Can any one explain about  Cube partitioning  &  time based Cube?

Cube partitioning is a process of consolidating records related to a dimension level or category.

Time-based partitioning exists to address the issue of updating large amounts of data in cubes.  Similar in some ways to incremental updates, time-based partitioning allows developers to add new data to a cube without having to modify any of the previous time partitions.
