Big data "size" is a constantly moving target; as of 2012 ranging from a few dozen terabytes to many zettabytes of data. [26] Big data requires a set of techniques and technologies with new forms of integration to reveal insights from data-sets that are diverse, complex, and of a massive scale. [27]
NOAA Big Data Project: NOAA generates tens of terabytes of data a day from satellites, radars, ships, weather models, and other sources. While these data are publicly available, it is difficult to download and work with such high volumes. NOAA’s vast wealth of data therefore represents a substantial untapped economic opportunity.
Machine learning, artificial intelligence, blockchains, predictive analytics – all amazing technologies which have promised to revolutionize business

Inclusion on the list doesn't automatically mean the absolute truth is on these websites, so always be critical and compare information between different sources. The content of the subsections is alphabetically organized. Please add free online sources if you know some that are missing in this list, but try to keep it relevant and trustworthy.
In many circumstances, these sources use inconsistent terms and definitions to describe the data content itself – making it hard to compare data, hard to automate business processes, hard to feed complex applications and hard to exchange data. This frequently results in a difficult process of data mapping and cross-referencing.
Data architecture should be defined in the planning phase of the design of a new data processing and storage system. The major types and sources of data necessary to support an enterprise should be identified in a manner that is complete, consistent, and understandable.
