Daniel Lemire <[EMAIL PROTECTED]> a décrit le projet comme suit : Licence: gpl Autre Licence: Paquet: Lemur OLAP Open Source Library Nom système: lemur Type: non-GNU Description: Lemur OLAP Open Source Library http://www.daniel-lemire.com/lemurOLAP/ Goals To our knowledge, there is no low level OLAP library implementing Hybrid OLAP. There is Mondrian which is a great Java-based ROLAP engine, but we believe that a smart C++ HOLAP implementation could outperform Mondrian. To be fair though, the primary goal of this library at this time is to support our research interests since our goal are probably too ambitious to deliver timely usable code. We do envision though that the library could be used soon for some niche applications. Licensing GPL, of course. Who are we? The project is lead by Daniel Lemire, researcher at the National Research Council of Canada, and Owen Kaser, associate professor at the University of New Brunswick (Saint John). Where's the source? You can download our C++ source package. It runs under Linux though it could be ported A recent compiler is assumed (gcc 3.2.2). It is licensed under GPL (even though, currently, there is no such notice in the source code). http://www.daniel-lemire.com/lemurOLAP/lemur_code.zip Suitability As of now, the package is not suitable for commercial usage and is of early alpha quality. However, it was succesfully used in a research context (see Kaser and Lemire, DOLAP'03). There is some level of regression testing, but we are still designing the API. We have setup a demo site where you can use the code through a web interface to prove that it does work. Dépendances logicielles: It runs under Linux though it could be ported eventually, a recent compiler is assumed (gcc 3.2.2). Currently, it is very minimalist though it is written in C++ and, as such, it requires C++ support... We plan to use libraries such as an embedded MySQL and BerkeleyDB in the future, but we would ensure that we can do so while remaining compliant with GPL. Autres Commentaires: I believe this may be the first ever C++ OLAP engine to be GPL. _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/ _______________________________________________ Savannah-hackers mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/savannah-hackers
