Workweek and weekend

The workweek and weekend are those complementary parts of the week devoted to labour and rest, respectively. The legal working week (British English), or workweek (U.S. English), is the part of the seven-day week devoted to labour. In most of the Western world it is Monday to Friday; the weekend is a time period including Saturday and Sunday. A weekday is any day of the working week. As well as places of work, other institutions often follow the same days, such as places of education.

Some people extend the weekend to Friday nights as well. In some Christian traditions, Sunday is the "Lord's Day" and the day of rest and worship. Jewish Shabbat or Biblical Sabbath lasts from sunset on Friday to the fall of full darkness on Saturday, leading to a Friday–Saturday weekend in Israel. Some Muslim-majority countries historically had a Thursday–Friday or Friday–Saturday weekend; however, recently many such countries have shifted from Thursday–Friday to Friday–Saturday, or to Saturday–Sunday. The French Revolutionary Calendar had ten-day weeks (called décades) and allowed décadi, one out of the ten days, as a leisure day.

Data

Data (/ˈdeɪtə/ DAY-tə, /ˈdætə/ DA-tə, or /ˈdɑːtə/ DAH-tə) is a set of values of qualitative or quantitative variables; restated, pieces of data are individual pieces of information. Data is measured, collected and reported, and analyzed, whereupon it can be visualized using graphs or images. Data as a general concept refers to the fact that some existing information or knowledge is represented or coded in some form suitable for better usage or processing.

Raw data, i.e. unprocessed data, is a collection of numbers, characters; data processing commonly occurs by stages, and the "processed data" from one stage may be considered the "raw data" of the next. Field data is raw data that is collected in an uncontrolled in situ environment. Experimental data is data that is generated within the context of a scientific investigation by observation and recording.

The Latin word "data" is the plural of "datum", and still may be used as a plural noun in this sense. Nowadays, though, "data" is most commonly used in the singular, as a mass noun (like "information", "sand" or "rain").

Big data

Big data is a broad term for data sets so large or complex that traditional data processing applications are inadequate. Challenges include analysis, capture, data curation, search, sharing, storage, transfer, visualization, querying and information privacy. The term often refers simply to the use of predictive analytics or certain other advanced methods to extract value from data, and seldom to a particular size of data set. Accuracy in big data may lead to more confident decision making, and better decisions can result in greater operational efficiency, cost reduction and reduced risk.

Analysis of data sets can find new correlations to "spot business trends, prevent diseases, combat crime and so on." Scientists, business executives, practitioners of medicine, advertising and governments alike regularly meet difficulties with large data sets in areas including Internet search, finance and business informatics. Scientists encounter limitations in e-Science work, including meteorology, genomics,connectomics, complex physics simulations, biology and environmental research.

John Mayer

John Clayton Mayer (/ˈmeɪ.ər/; born October 16, 1977) is an American singer-songwriter and producer. He was born in Bridgeport, Connecticut, and raised in nearby Fairfield. He attended Berklee College of Music in Boston, Massachusetts, but disenrolled and moved to Atlanta, Georgia, in 1997 with Clay Cook. Together, they formed a short-lived, two-man band called Lo-Fi Masters. After their split, Mayer continued to play local clubs—refining his skills and gaining a following. After his appearance at the 2001 South by Southwest Festival, he was signed to Aware Records, and then Columbia Records, which released his first EP, Inside Wants Out. His following two full-length albums—Room for Squares (2001) and Heavier Things (2003)—did well commercially, achieving multi-platinum status. In 2003, he won the Grammy Award for Best Male Pop Vocal Performance for the single "Your Body Is a Wonderland".

Though Mayer started his career mainly performing acoustic rock, he began moving towards the blues genre that had originally influenced him as a musician. By 2005, he was collaborating with blues artists such as B. B. King, Buddy Guy, and Eric Clapton. Forming the John Mayer Trio, he released a live album in 2005 called Try!, and his third studio album Continuum in 2006. Both albums received wide critical acclaim, and Continuum earned Mayer a 2007 Grammy Award for Best Pop Vocal Album. He also won Best Male Pop Vocal Performance for "Waiting on the World to Change". That album was followed by Battle Studies in 2009, a return to pop, with a number-one grossing tour.
