Questions tagged [view]

This tag is for questions about database view or UI / architectural view. See also the following tags: sql-view, android-view, uiview.

The purpose of almost any computer program is to process data in one form or another. When the program requires user interaction it is often necessary to provide the user with a view of that data to represent it in a useful and comprehensible manner.

View also refers to:

  • A stored query in a relational database that can be accessed as if it were a table.
  • The display or presentation layer of a MVC architecture.

Questions tagged should also be tagged with the relevant language.
