Welcome to OGSA-DAI!

OGSA-DAI is a product that allows data in distributed databases to be accessed, updated, transformed and combined. OGSA-DAI has a powerful distributed query processor that allows queries to be run over many databases as if they were a single database. OGSA-DAI can be used with relational and XML databases and with file systems. OGSA-DAI is a fully-customisable framework that can be tailored to the exact requirements of specific projects and business communities.

OGSA-DAI is used by research and business users around the world, in a variety of areas including geographical information systems, meteorology, transport, computer-aided design, engineering, astronomy and medical research.

OGSA-DAI software is free, open-source and driven by a world-wide community.
