Indexed Database API


Indexed Database API

The Indexed Database API, or Indexed DB (formerly WebSimpleDB), is a proposed[1] web browser standard interface for a local database of records holding simple values and hierarchical objects. Indexed DB was initially proposed by Oracle in 2009.[2]

Indexed DB could be used for browser implemented functions, such as bookmarks, as well as web applications, such as email. An open-source reference implementation of the Indexed Database API exists for testing and experimentation purposes.[3]

Preliminary support for Indexed DB is included by Firefox (since version 4[4]),Google Chrome (since version 11[5]), and by the Internet Explorer 10 Consumer Preview and Metro style apps.[6]

Safari, Chrome 4 and Opera support[7] an alternate mechanism for client-side database storage called Web SQL Database.[8] On November 18, 2010, the W3C announced that the Web SQL database specification is in impasse and is no longer being actively worked on.[9]Firefox developers have publicly stated that the lack of WebSQL Database support in Firefox is on purpose, as they believe it is a problematic standard which requires an alternative (hence IndexedDB).[10]
