Summary statistical measures represent the key properties of a sample or population as a single numerical value. This has the advantage of providing important information in a very compact form. It also simplifies comparing multiple samples or populations. Summary statistical measures can be divided into three types: measures of central tendency, measures of central dispersion, and measures of association.

To stay competitive today, companies must find practical ways to deal with big data — that is, to learn new ways to capture and analyze growing amounts of information about customers, products, and services.Data is becoming increasingly complex in structured and unstructured ways.

Dealing with dates can be a bit tricky, partly because of the variety of ways to store them.

ETL tools combine three important functions (extract, transform, load) required to get data from one big data environment and put it into another data environment.

One area where big data has made an impact on electric utilities is the development of smart meters. Smart meters provide a more accurate measure of energy usage by giving far more frequent readings than traditional meters. A smart meter may give several readings a day, not just once a month or once a quarter.

While the worlds of big data and the traditional data warehouse will intersect, they are unlikely to merge anytime soon.
