What is SQLite?
SQLite is a lightweight, serverless database engine that stores an entire database in a single file. It is widely used in applications because it requires minimal setup, has a small footprint, and supports most common SQL features (such as SELECT, INSERT, UPDATE, and DELETE). Unlike many client-server databases, SQLite runs inside the same process as the application that uses it, which can simplify deployment and improve reliability for local or embedded data needs.

Key characteristics and common uses
SQLite is ACID-compliant (atomicity, consistency, isolation, durability), making it suitable for transactional data. It supports indexing, constraints, and prepared statements, and it can handle many real-world workloads effectively—especially when data size is moderate and concurrency requirements are not extreme. Common uses include mobile apps, desktop software, embedded systems, browser storage, and local caching.

How it’s typically used
Applications interact with SQLite through a library or driver, executing SQL statements against the database file. Developers often create tables, define schemas, and run queries to read and write data. Because it is file-based, backup and migration typically involve copying the database file (with care to avoid copying while it’s actively being written).
