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 [[http://www.gnu.org/licenses/old-licenses/gpl-2.0.html|GPL2]] or (at your option) any later version. ===== Release Status ===== WDB version 0.7.0 is [[http://wdb.met.no/download/wdb-0.7.0.tar.gz|now available]]. It is the first version of WDB which will be used in a production setting by met.no (a multi-terabyte field archive). ===== 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++; it should be usable in C, Java, Perl, Python, and Fortran as well (however, these interfaces are not yet tested). ===== WDB Roadmap ===== See the [[developers:roadmap]] for a detailed roadmap of WDB, broken down by release. On the executive level, the future development of WDB is targetted toward: * Putting WDB into production in the Hindcast project (multi-terabyte forecast field archive) * Improving the performance of the overall system; but in particular the extraction of forecast points from fields in time series * Improving the test framework and documentation * Creating a load-balancing and fail-over solution for the WDB system ~~NOTOC~~ wdb/start.1207124612.txt.gz Last modified: 2022-05-31 09:23:29(external edit)
