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](https://en.wikipedia.org/wiki/Relational_database_management_system), IndexedDB is a transactional database system. However, it uses {{glossary("JavaScript")}} objects rather than fixed columns tables to store data.
