data processing


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.
