Data processing is, broadly, "the collection and manipulation of items of data to produce meaningful information." In this sense it can be considered a subset of ''information processing'', "the change (processing) of information in any manner detectable by an observer." 〔Data processing is distinct from ''word processing'', which manipulates text rather than data.(【引用サイトリンク】url=http://www.webopedia.com/TERM/D/data_processing.html )〕 The term is often used more specifically in the context of a business or other organization to refer to the class of commercial data processing applications. ==Data processing functions== Data processing may involve various processes, including: * Validation – Ensuring that supplied data is "clean, correct and useful" * Sorting – "arranging items in some sequence and/or in different sets." * Summarization – reducing detail data to its main points. * Aggregation – combining multiple pieces of data. * Analysis – the "collection, organization, analysis, interpretation and presentation of data.". * Reporting – list detail or summary data or computed information. * Classification – separates data into various categories. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Data processing」の詳細全文を読む スポンサード リンク
