Database
Systematically organized or structured repository of indexed information (usually as a group of linked data files) that allows easy retrieval, updating, analysis, and output of data. Stored usually in a computer, this data could be in the form of graphics, reports, scripts, tables, text, etc., representing almost every kind of information. Most computer applications (including antivirus software, spreadsheets, word-processors) are databases at their core. See also flat database and relational database.
