	Data Policy
		From this data it is possible to determine which geographical territory you are located - assuming that you are dialling into a local provider.
		The data may be passed on to advertisers or advertising agencies so that targeted advertising can be provided to you.
		It is the intention to monitor overall trends and statistics and there is no intention to provide "data mining" facilities so that individuals and their behaviour can be monitored unless such information is required by lawful authorities.

	Data grid - Wikipedia, the free encyclopedia
		A data grid is a grid computing system that deals with data—the controlled sharing and management of large amounts of distributed data.
		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.
		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.

	Bridging the integration gap, Part 1: Bridging the integration gap: Federating grid data
		Data location, data access methods, and data source are all transparent to the application.
		Data is pipelined between different sets of activities that operate on a data stream coming out of, or going into, a data resource.
		The registry is a key concept of a data grid, and it is our opinion that it is important to allow this registry to be updated from any service or component within the grid.

	Inside Architecture : The event driven Persistent Data Grid
		The data grid is not a new concept.
		One assumption of the data grid is that the memory is large enough to store and retrieve the data.
		Depending on policies, the grid clusters can request full data for the data item from the source system, or they can wait until full data is requested by an app.

	Beehive NetUI Data Grids
		This data grid binds to a List of PetBean objects stored in the PageContext's attribute map and renders an HTML table that is four cells wide (i.e., four columns) containing the petId, name, description, and price fields.
		Cells in the body of the data grid are used to render the grid's data; the spanCell tags in the simple example above are an example of this.
		By default, the data grid renders a set of HTML style class names which can be used in conjunction with a user-provided CSS file to automatically apply styles to the grid.

		The case study describes how one bank is using grid data services to provision data to more than 40 distributed grid applications for front and middle office equity trading.
		Synchronizing silo data is complex and error-prone: Most silo applications have their own operational datastores, thereby creating a complex data synchronization infrastructure, particularly for shared data about products, partners, and customers.

	Grid Solutions - Data Replication for LIGO
		The data generated by a LIGO run must be scientifically analyzed for it to be of any value.
		The data management challenge faced by LIGO is therefore to replicate approximately 1 TB/day of data to multiple sites securely, efficiently, robustly, and automatically; to keep track of where replicas have been made for each piece of the data; and to use the data in a multitude of independent analysis runs.
		Data transfer endpoints should be authenticated using "strong" security, and data transfers should preserve data integrity.

	Marc Hamilton's Weblog : Weblog
		What LHC plans to do (and is already doing with sample data) is put those 15 PB of data up on their Data Grid which is distributed throughout the world at a number of different data centers.
		A small number of Tier 1 data centers each hold master copies of large subsets of the data while a larger number of Tier 2 data centers store and process smaller subsets.
		There are already startup companies like Exludus that make software for data grids (full disclosure, Exludus' founder previously managed Sun's HPC business in Europe and was based down the street from CERN in Sun's Geneva office and no doubt his startup was inspired by the requirements of HPC projects such as those at CERN).

	Nature Web Matters > Internet Computing and the Emerging Grid
		Grid computing concepts were first explored in the 1995 I-WAY experiment, in which high-speed networks were used to connect, for a short time, high-end resources at 17 sites across North America.
		No formal standards process as yet exists for Grids (the Grid Forum is working to create one).
		The result will be integrated Grids in which problems of different types can be routed to the most appropriate resource: dedicated supercomputers for specialized problems that require tightly coupled processors and idle workstations for more latency tolerant, data analysis problems.

	Data
		The GEO Data Portal is the authoritative source for data sets used by UNEP and its partners in the Global Environment Outlook (GEO) report and other integrated environment assessments.
		In Africa, the regional Data Portal has already progressed substantially, being compatible with the global Data Portal and envisaged to capture much more data and indicators to serve the GEO process, including the African Environment Outlook and other initiatives in and of the region.
		These data sets are always spatially referenced; that is, they carry geographic information that allows them to be used in analyses of both the human and physical environments, typically using GIS and Image Processing (IP) software.

	Grid watch: GGF and grid data
		Before you can do anything with data, you have to know where it is and what it is. That means you have to have a metadata system in place to accurately describe the data no matter where it lives -- and this system must work across different environments.
		Data virtualization is important because it allows for a kind of mapping between the actual data entities and how they're represented in an abstraction layer.
		Ian Foster's paper on the "Anatomy of the Grid" at http://www.globus.org/research/papers/anatomy.pdf is pretty much required reading, as is his paper on the "Physiology of the Grid" at http://www.globus.org/research/papers/physiology.pdf.

		A grid view or a datagrid is a graphical user interface element (widget) that presents a tabular view of data.
		Grid views are sometimes referred to as spreadsheet widgets (or spreadsheet controls, with control being a common synonym for widget).
		This is due to grid views' visual and sometimes behavioral similarity to spreadsheet applications.

	Grid computing - Wikipedia, the free encyclopedia
		Grid computing is an emerging computing model that provides the ability to perform higher throughput computing by taking advantage of many networked computers to model a virtual computer architecture that is able to distribute process execution across a parallel infrastructure.
		Grids provide the ability to perform computations on large data sets, by breaking them down into many smaller ones, or provide the ability to perform many more computations at once than would be possible on a single computer, by modeling a parallel division of labor between processes.
		Grid computing offers a model for solving massive computational problems by making use of the unused resources (CPU cycles and/or disk storage) of large numbers of disparate computers, often desktop computers, treated as a virtual cluster embedded in a distributed telecommunications infrastructure.

	alphaWorks : Grid Wrapper for WebSphere Information Integrator : Overview
		Grid Wrapper for WebSphere Information Integrator enables applications that currently access DB2 (or any other RDBMS) to transparently access a fully-distributed database over the grid with minimum changes.
		A registry (either XML or relational) key to this wrapper enables the dynamic aspects of the grid to be fully used.
		For instance, the registry allows the system to cope with failure by finding the next available database on the grid with similar information; finding this database enables the application to fetch results in parallel from multiple databases or replicas on the grid.
