What is SQLite?

SQLite is an open-source, serverless, and lightweight relational database management system (RDBMS) that is designed to be used in embedded systems and other applications where a full-fledged RDBMS is not needed. It is a software library that provides a self-contained and transactional SQL database engine.

SQLite is written in the C programming language and is widely used due to its simple, fast, and low-overhead design. It is also easy to use and has a small binary size, making it ideal for use in embedded systems.

The database engine is a part of the operating system, and it can be used without the need for any additional software. This makes SQLite a popular choice for developers who need to store data without the need for a full-fledged database server.

The values kept in a column can be categorized using one of SQLite’s several storage classes or data types.
