SQLite

SQLite is a lightweight, self-contained, serverless, zero-configuration, transactional SQL database engine. It is the most widely deployed database in the world with over 1 trillion installations. It is used in countless applications, from web browsers to operating systems. It is fast, reliable, and requires minimal setup and maintenance. It supports most of the SQL standard, including transactions, triggers, and views. It is also highly extensible, allowing developers to create custom functions and extensions.
