SQLite
SQLite is a lightweight, open-source relational database management system that uses SQL (Structured Query Language) to manage data. It is a popular choice for small to medium-sized applications due to its simplicity and ease of use.
History
SQLite was first released in 2000 by D. Richard Hipp as a simple, lightweight, and self-contained database engine. It is designed to be embedded in applications and does not require a separate server process or configuration.
Architecture
SQLite is a C library that provides an SQL database engine. The core SQLite library is written in C which all lives in a single directory.
