Big Data

Wikipedia has this to say about big data:

In information technology, big data^[1] consists of datasets that grow so large that they become awkward to work with using on-hand database management tools. Difficulties include capture, storage,^[2] search, sharing, analytics,^[3] and visualizing. This trend continues because of the benefits of working with larger and larger datasets allowing analysts to "spot business trends, prevent diseases, combat crime."^[4]

There are at least two main players: Hadoop and HPCC. Of note, many of the developers who created Clarion for Windows now work on HPCC.
