OGSA-DAI - Distributed Query Processing on the Grid

A study of Grid applications has shown that the prospect exists for literally billions of data resources and petabytes of data being accessible in a Grid environment. It is therefore to be expected that many of the advances to flow from the Grid will come from applications that can combine information from multiple data sets. This will allow researchers to combine different types of information on a single entity to gain a more complete picture, and to aggregate the same types of information about different entities. In this project we are developing a distributed query processing system for databases on the Grid. Users specify their query a high-level, declarative language that allows them to express both data access and analysis.
