SQLite is a relational database management system (RDBMS) that is available as open-source software. It was originally released in 2000 and is written in the C programming language. SQLite is known for its lightweight nature and its ability to operate without a dedicated server, meaning the database is stored in a single file on the file system.
Here are some key features of SQLite:
Serverless: Unlike many other database management systems, SQLite does not require a separate server process. Applications can directly access the SQLite database file.
Embeddable: SQLite is typically embedded within other applications and is commonly used in mobile applications, desktop applications, and embedded systems.
Transaction support: SQLite supports transactions, ensuring data integrity and consistency.
ACID properties: SQLite ensures the ACID properties (Atomicity, Consistency, Isolation, Durability) for transactions.
Cross-platform: SQLite is cross-platform and available on various operating systems, including Windows, macOS, Linux, and many others.
Self-contained database file: The entire database is stored in a single file on the file system, making it easy to manage and exchange data.
Support for many programming languages: There are SQLite bindings for many programming languages, including C/C++, Python, Java, C#, and many others.
SQLite is often used for applications where a lightweight and embedded database solution is needed, without the complexity and resource requirements of larger RDBMS like MySQL, PostgreSQL, or Oracle. It is well-suited for small to medium-sized projects, prototypes, and situations where a simple database is required.
