:Version: |version|

The FDB is a domain-specific object store developed at ECMWF for
storing, indexing and retrieving GRIB data. Each GRIB message is stored as a
field and indexed trough semantic metadata (i.e., physical variables such as
temperature, pressure, …). A set of fields can be retrieved specifying a
request using a specific language developed for accessing MARS Archive.
