Data grid

A data grid is a grid computing system that deals with data - the controlled sharing and management are large amounts of distributed data. These are often, but not always, combined with computational grid computing systems.
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 perfomances increase, and new computational science applications are developed.
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 underlaying 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.
