IndexedDB - An Efficient Way to Manage Data

1. IndexedDBAn Efficient Way to Manage Data By SPEC INDIA

2. What is IndexedDb • A web browser standard interface for a local database of records • Holds simple values and hierarchical objects • An API for client-side storage of significant amounts of structured data • Exhibits High performance • Storage and retrieval done through keys or indexes

3. The Object Store • The IndexedDB is made of records called an Object Store • Each of the records consists of a key path and a corresponding value • Each Object Store can have a collection of Indexes for efficient Queries

4. Browser Integration • IE 10.0+ • Firefox Mozilla 28.0+ • Chrome 33.0 • Safari 8.0+ • Opera 22.0+

5. Features • Full functionality even if a network connection is not available • No data loss on network interruption • Can cache data and restore state between invocations • Generates less network traffic • Data management happens on the local computer rather than over the Internet • Supports transactions and cursors • Allows faster indexing and searching of objects, enabling better data management • Supports both synchronous and asynchronous API

6. Comparison with the Alternatives

7. Database Features • It is Object-oriented and not Relational Database • IndexedDBstores key-value pairs • The API is mostly asynchronous & does not have a return value • Works using Cursors based on indexes rather than SQL, to increase the speed • Prevents applications from accessing data with a different origin
