Data
Data (/ˈdeɪtə/ DAY-tə, US also /ˈdætə/ DAT-ə) are a collection of discrete or continuous values that convey information, describing the quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted formally. A datum is an individual value in a collection of data. Data are usually organized into structures such as tables that provide additional context and meaning, and may themselves be used as data in larger structures. Data may be used as variables in a computational process.[1][2] Data may represent abstract ideas or concrete measurements.[3] Data are commonly used in scientific research, economics, and virtually every other form of human organizational activity. Examples of data sets include price indices (such as the consumer price index), unemployment rates, literacy rates, and census data. In this context, data represent the raw facts and figures from which useful information can be extracted.
Data are collected using techniques such as measurement, observation, query, or analysis, and are typically represented as numbers or characters that may be further processed. Field data are data that are collected in an uncontrolled, in-situ environment. Experimental data are data that are generated in the course of a controlled scientific experiment. Data are analyzed using techniques such as calculation, reasoning, discussion, presentation, visualization, or other forms of post-analysis. Prior to analysis, raw data (or unprocessed data) is typically cleaned: Outliers are removed, and obvious instrument or data entry errors are corrected.
Data can be seen as the smallest units of factual information that can be used as a basis for calculation, reasoning, or discussion. Data can range from abstract ideas to concrete measurements, including, but not limited to, statistics. Thematically connected data presented in some relevant context can be viewed as information. Contextually connected pieces of information can then be described as data insights or intelligence. The stock of insights and intelligence that accumulate over time resulting from the synthesis of data into information, can then be described as knowledge. Data has been described as "the new oil of the digital economy".[4][5] 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.
Advances in computing technologies have led to the advent of big data, which usually refers to very large quantities of data, usually at the petabyte scale. Using traditional data analysis methods and computing, working with such large (and growing) datasets is difficult, even impossible. (Theoretically speaking, infinite data would yield infinite information, which would render extracting insights or intelligence impossible.) In response, the relatively new field of data science uses machine learning (and other artificial intelligence) methods that allow for efficient applications of analytic methods to big data.
Poole (/puːl/ (audio speaker iconlisten)) is a large coastal town and seaport in Dorset, on the south coast of England. The town is 21 miles (34 km) east of Dorchester and adjoins Bournemouth to the east. Since 1 April 2019, the local authority is Bournemouth, Christchurch and Poole Council which is a unitary authority. Poole had an estimated population of 151,500 (mid-2016 census estimates) making it the second-largest town in the ceremonial county of Dorset. Together with Bournemouth and Christchurch, the conurbation has a total population of nearly 400,000.
Human settlement in the area dates back to before the Iron Age. The earliest recorded use of the town's name was in the 12th century when the town began to emerge as an important port, prospering with the introduction of the wool trade. Later, the town had important trade links with North America and, at its peak during the 18th century, it was one of the busiest ports in Britain. In the Second World War, Poole was one of the main departing points for the Normandy landings.
Poole is a tourist resort, attracting visitors with its large natural harbour, history, the Lighthouse arts centre and Blue Flag beaches. The town has a commercial port with cross-Channel freight and passenger ferry services, which connect with the Channel Islands of Jersey and Guernsey, as well as the French port town of Saint-Malo, Brittany.
The headquarters of the Royal National Lifeboat Institution (RNLI) is in Poole, and the Royal Marines have a base in the town's harbour. Despite their names, Poole is the home of The Arts University Bournemouth, the Bournemouth Symphony Orchestra and a significant part of Bournemouth University.
