Data (or) is a set of values of qualitative or quantitative variables.

An example of qualitative data would be an anthropologist's handwritten notes about his or her interviews with people of an Indigenous tribe.

Pieces of data are individual pieces of information.

While the concept of data is commonly associated with scientific research, data is collected by a huge range of organizations and institutions, including businesses (e.g., sales data, revenue, profits, stock price), governments (e.g., crime rates, unemployment rates, literacy rates) and non-governmental organizations (e.g., censuses of the number of homeless people by non-profit organizations).

The shapefile format is a popular geospatial vector data format for geographic information system (GIS) software.

It is developed and regulated by Esri as a (mostly) open specification for data interoperability among Esri and other GIS software products.

The shapefile format can spatially describe vector features: points, lines, and polygons, representing, for example, water wells, rivers, and lakes.

Each item usually has attributes that describe it, such as name or temperature.

A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes.

A data set (or dataset) is a collection of data.

Most commonly a data set corresponds to the contents of a single database table, or a single statistical data matrix, where every column of the table represents a particular variable, and each row corresponds to a given member of the data set in question.

The data set lists values for each of the variables, such as height and weight of an object, for each member of the data set.

Each value is known as a datum.

The data set may comprise data for one or more members, corresponding to the number of rows.

The term data set may also be used more loosely, to refer to the data in a collection of closely related tables, corresponding to a particular experiment or event.

An example of this type is the data sets collected by space agencies performing experiments with instruments aboard space probes.

Data sets that are so large that traditional data processing applications are inadequate to deal with them are known as big data.
