What are data sources in technology? A data source is the location where data that is being used originates from. A data source may be the initial location where data is born or where physical information is first digitized, however even the most refined data may serve as a source, as long as another process accesses and utilizes it.
Various databases are examples of data sources. Consider a shoe brand that sells things online. The website uses data from a stock database to determine if a product is out of stock. The stock records are a data source in this scenario, which is retrieved by the web program that provides the website to consumers.
