GFBio

Environmental and biological research is becoming central to major societal challenges related to the Earth’s ecosystems and climate dynamics.

To handle the scale and complexity of the scientific questions being addressed, there is a strong need to integrate knowledge because biological data are currently scattered and difficult to share. We propose here a coherent infrastructure to improve scientific data integration and preservation.

XXL - eXtensible and fleXible Library

XXL is a Java library that contains a rich infrastructure for implementing advanced query processing functionality. The library offers low-level components like access to raw disks as well as high-level ones like a query optimizer. On the intermediate levels, XXL provides a demand-driven cursor algebra, a framework for indexing and a powerful package for supporting aggregation. The XXL project provides various packages. See the longer introduction to XXL for an explanation of the packages.
