From RuntimeWiki
This feature request is about more advanced local storage features, generally in the flavor of SQL-like capabilities, that are beyond the features available via DOM Storage (which offers simple name-value-pair storage via the localStorage and sessionStorage objects).

Microsoft and Mozilla declared their intention to advance WebSimpleDB and their preference for it over WebDatabase/WebSQLDatabase:
