====== WDB - Weather and Water Database ======

Welcome to the **WDB** project's home page.

**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 the backbone of [[http://www.yr.no|yr.no]]; Scandinavia's largest weather site.

The WDB system consists of a database server system including a read/write interface to the database, a set of loading programs for inserting various types of MHO data into the system, and a http product generator.


===== WDB Features =====

  * **Decode and store meteorological and oceanographic forecast fields**
    * WDB has loading programs to load forecasts, analysis, wave and circulations models stored in GRIB1 and FELT format. Metadata is provided for HIRLAM 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).

  * **Open Source**
    * WDB is licensed under [[http://www.gnu.org/licenses/old-licenses/gpl-2.0.html|GPL2]] or (at your option) any later version.
