IndexedDB

IndexedDB is a Web {{glossary("API")}}  for storing large data structures within browsers and indexing them for high-performance searching. Like an {{glossary("SQL")}} -based RDBMS, IndexedDB is a transactional database system. However, it uses {{glossary("JavaScript")}}  objects rather than fixed columns tables to store data.
