Characteristics of big data include high volume, high velocity and high variety. Big data is a field that treats ways to analyze, systematically extract information from, or otherwise deal with data sets that are too large or complex to be dealt with by traditional data-processing application software.Data with many cases (rows) offer greater statistical power, while data with higher complexity (more attributes or columns) may lead to a higher false discovery rate.

See Seth Grimes piece on how “Wanna Vs” are being irresponsible attributing additional supposed defining characteristics to Big Data: http://www.informationweek.com/big-data/commentary/big-data-analytics/big-data-avoid-wanna-v-confusion/240159597. With the many configurations of technology and each configuration being assessed a different value, it's crucial to make an assessment about the product based on its specific configuration. Social Media The statistic shows that 500+terabytes of new data get ingested into the databases of social media site Facebook, every day. Purchasing is just one use case that points to the need large enterprises have in using their systems of record to drive the big data analytics they perform. Jeff Veis, VP Solutions at HP Autonomy presented how HP is helping organizations deal with big challenges including data variety. Here comes a new big-data approach trying to crack the age-old problem of understanding what a TV show or movie is really about. The variety in data types frequently requires distinct processing capabilities and specialist algorithms. "We use an API (application programming interface) so the service can be instrumented into different procurement applications," said Palmer. The following are common examples of data variety. Roughly 95% of all big data is unstructured, meaning it does not fit easily into a straightforward, traditional model. They could only do this by using their systems of record, and the organization of data inherent in those systems, as drivers for their big data analytics.

Through the use of machine learning, unique insights become valuable decision points. Clearly valid data is key to making the right decisions. The problem is especially prevalent in large enterprises, which have many systems of record and also an abundance of data under management that is structured and unstructured. Palmer says that data "curation" is one way to attack the variety issue that comes with having to navigate through not only multiple systems of record systems but multiple big data sources. Yes they’re all important qualities of ALL data, but don’t let articles like this confuse you into thinking you have Big Data only if you have any other “Vs” people have suggested beyond volume, velocity and variety. See my InformationWeek debunking, Big Data: Avoid ‘Wanna V’ Confusion, http://www.informationweek.com/big-data/news/big-data-analytics/big-data-avoid-wanna-v-confusion/240159597, Glad to see others in the industry finally catching on to the phenomenon of the “3Vs” that I first wrote about at Gartner over 12 years ago.
