Web SQL Database is a web page API for storing data in databases that can be queried using a variant of SQL.
The API is supported by Google Chrome, Opera, Safari and Mozilla Firefox by add-on extension.
The W3C Web Applications Working Group ceased working on the specification in November 2010, citing lack of independent implementations (not using SQLite as the backend) as the reason the specification could not move forward to become a W3C Recommendation.
