The next version of [[NetCDF]], version 4, is based on HDF5.

Because it uses [[B-Trees]] to index table objects, it works well for [[Time series]] data like stock market ticks or network monitoring data. The bulk of the data goes into straightforward arrays (the table objects) that can be accessed much quickermore quickly than the rows of an SQL database. But you still have B-Tree access for non-array data. If you find yourself designing a [[Star schema]] to fit your data into SQL, then you might want to investigate HDF5 as a simpler, faster alternative storage mechanism.
