SQLite is an open-source, serverless, self-contained, zero-configured, transactional SQL database engine. It is the most widely deployed database in the world and is used in a wide variety of applications, from web apps and e-commerce sites to embedded devices, mobile devices, and desktop applications. SQLite is designed to be highly reliable, compact, and secure. It is self-contained, meaning that it does not require any additional software for it to work, and is also highly portable, allowing it to be used across multiple platforms. It is also a serverless database, so there is no need to install and configure a database server. SQLite also provides a number of features to help ensure data integrity, such as multi-version concurrency control and atomic commit. Additionally, SQLite is highly extensible and customizable, allowing developers to tailor the database to their needs. It also offers a wide range of built-in functions, including full-text search and JSON storage. Finally, SQLite is open-source, meaning that it can be used without any licensing fees.
