Data Web refers to a government open source project that was started in 1995 to develop open source framework that networks distributed statistical databases together into a seamless unified virtual data warehouse.

Originally funded by the U.S. Census Bureau, with participation at various times by the Bureau of Labor Statistics, the Centers for Disease Control, Harvard University and other non-profits. The software provides an open source service oriented architecture that pulls data from different data base structures and vendors that normalizes it into a standard stream of data. The normalized stream is intelligent and supports standard transformations, has the intelligence to understand how to geographically map itself correctly using the correct vintage of political geography, understands standard code-sets so that data can be combined in statistical appropriate ways, understands how weight survey data appropriately, understands variance and other appropriate statistical behaviors.

The DataWeb network handles small data sets and very large datasets; including of course the Census. It contains the Tiger GIS mapping files to support appropriate mapping of all of the human based (i.e. political jurisdictions) geography in the United States.

Data ( /ˈdeɪtə/ DAY-tə, /ˈdætə/ DA-tə, or /ˈdɑːtə/ DAH-tə) are values of qualitative or quantitative variables, belonging to a set of items. Data in computing (or data processing) are often represented by a combination of items organized in rows and multiple variables organized in columns. Data are typically the results of measurements and can be visualised using graphs or images. Data as an abstract concept can be viewed as the lowest level of abstraction from which information and then knowledge are derived. Raw data, i.e., unprocessed data, refers to a collection of numbers, characters and is a relative term; data processing commonly occurs by stages, and the "processed data" from one stage may be considered the "raw data" of the next. Field data refers to raw data collected in an uncontrolled in situ environment. Experimental data refers to data generated within the context of a scientific investigation by observation and recording.

The word data is the plural of datum, neuter past participle of the Latin dare, "to give", hence "something given". In discussions of problems in geometry, mathematics, engineering, and so on, the terms givens and data are used interchangeably. Such usage is the origin of data as a concept in computer science or data processing: data are numbers, words, images, etc., accepted as they stand.
