A data grid is a grid computing system that deals with data — the controlled sharing and management of large amounts of distributed data. These are often, but not always, combined with computational grid computing systems. Image File history File links Please see the file description page for further information. ...

Many scientific and engineering applications require access to large amounts of distributed data (terabytes or petabytes). The size and number of these data collections has been growing rapidly in recent years and will continue to grow as new experiments and sensors come on-line, the costs of computation and data storage decrease and performances increase, and new computational science applications are developed. Look up computation in Wiktionary, the free dictionary. ... Computational Science is the use of computers to perform research in other fields. ...

Current large-scale data grid projects include the Biomedical Informatics Research Network (BIRN), the Southern California Earthquake Center (SCEC), and the Real-time Observatories, Applications, and Data management Network (ROADNet), all of which make use of the SDSC Storage Resource Broker as the underlying data grid technology. These applications require widely distributed access to data by many people in many places. The data grid creates virtual collaborative environments that support distributed but coordinated scientific and engineering research. The Biomedical informatics Research Network or BIRN is a National Institutes of Health initiative providing a framework of people and information technology infrastructure, notably a grid of supercomputers, for distributed collaborations in biomedical science. ...
