WDB

WDB is a database system designed to store MHO (Meteorological, Hydrological and Oceanographic) 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 complete, flexible, and effective data storage solution for real-time and archive data.

WDB is an open-source project licensed under GPL2.

Latest Release

There is no current release of WDB.

WDB 0.6rc1 can be (downloaded); however, note that the WDB system is still under development; we do not recommend the use of 0.6rc1 for production.

WDB Features

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++

The interface should be usable in C, Java, Perl, Python, and Fortran as well, but these interfaces are yet to be tested

WDB Roadmap

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
