Internet Explorer 10 and Windows Store apps using JavaScript introduce support for the Indexed Database API ("IndexedDB"). IndexedDB enables you to store structured data. Unlike cookies and DOM Storage, IndexedDB provides features that enable you to group, iterate, search, and filter JavaScript objects.

The IndexedDB API is defined by the World Wide Web Consortium (W3C)'s Indexed Database API specification, which is currently in the Working Draft stage.

IndexedDB objects

The IndexedDB API consists of several objects, each designed for specific tasks.

Asynchronous versus synchronous

The Indexed Database API specification defines two APIs: a synchronous API and an asynchronous one. Internet Explorer 10 supports the asynchronous API.
