WDB

WDB is a database system designed to store meteorological, hydrological and oceanographic (MHO) data in a PostgreSQL database management server. The purpose of the WDB system is to improve the quality and effectiveness of IT systems for MHO production by providing a flexible and effective data storage solution for real-time and archive data.

WDB is an open-source project licensed under GPL2 or (at your option) any later version.

The WDB system is currently in development.

The latest stable version of the source code is WDB version 0.6rc2 (available for download here). It is not recommended for production usage, however. Use at own risk.

• Decode and store meteorological forecast fields
  • WDB has loading programs to load forecasts, analysis, etc. stored in GRIB1 format. Metadata is provided for HIRLAM fields

• Decode and store oceanographic fields
  • WDB has loading programs to load wave and circulation models stored in GRIB1 files. Metadata is provided for WAM fields

• Flexible retrieval interface
  • The WDB Call Interface (WCI) allows the extraction of entire fields or points (time-series) from the database using an SQL-based function interface.
  • WCI is compatible with C++; it should be usable in C, Java, Perl, Python, and Fortran as well (however, these interfaces are not yet tested).

• Putting WDB into production in the Hindcast project (multi-terabyte forecast field archive)
• Creating a load-balancing and fail-over solution for the WDB system
• Improving the test framework and documentation
• Improving the performance of the overall system; but in particular the extraction of forecast points from fields in time series
