Data set

<p>A data set (or dataset) is a collection of <a href="/facts/Data/AUBFN97o">data</a>. In the case of tabular data, a data set corresponds to one or more <a href="/facts/Table_(database)/5INvK1Vd">database tables</a>, where every <a href="/facts/Column_(database)/WB91xSVs">column</a> of a table represents a particular <a href="/facts/Variable_(computer_science)/VoCKtwml">variable</a>, and each <a href="/facts/Row_(database)/PIpv7c9e">row</a> corresponds to a given <a href="/facts/Record_(computer_science)/1fvSgenB">record</a> of the data set in question. The data set lists values for each of the variables, such as for example height and weight of an object, for each member of the data set.  Data sets can also consist of a collection of documents or files.
</p><p>In the <a href="/facts/Open_data/h9695bNE">open data</a> discipline, data set is the unit to measure the information released in a public open data repository.  The European <a href="/facts/Data.europa.eu/wpbXkuKN">data.europa.eu</a> portal aggregates more than a million data sets.
