What is SQLite

• SQLite is a software library that provides a relational database management system (RDBMS). It is a self-contained, serverless, and zero-configuration database engine that is widely used in various applications and programming languages. The name "SQLite" stands for "Structured Query Language (SQL) Lite."

• SQLite is designed to be embedded within applications, meaning it is not a separate standalone database server like MySQL or PostgreSQL. Instead, it is directly integrated into an application's code and operates as a library, allowing applications to manage and interact with a relational database without the need for a separate database server process.

Here are some key features of SQLite:

• Serverless: SQLite does not have a separate server process. The entire database resides in a single file on the disk, making it easy to manage and distribute along with the application.

• Zero-configuration: SQLite does not require any configuration or setup. It automatically creates and manages the database file, eliminating the need for complex installation or administration.

• Relational Database: SQLite supports the relational database model, allowing you to define tables with columns and relationships between them. You can perform various SQL operations like creating tables, inserting data, querying data, updating records, and deleting data.

• ACID-compliant: SQLite ensures data integrity by providing support for atomicity, consistency, isolation, and durability (ACID) properties. It ensures that transactions are processed reliably and without data corruption.

• Lightweight and Efficient: SQLite is designed to be lightweight and efficient, making it suitable for resource-constrained environments. It has a small memory footprint and performs well even with large datasets.

• Cross-platform: SQLite is cross-platform and works on various operating systems, including Windows, macOS, Linux, and mobile platforms like iOS and Android. It has bindings and APIs available for multiple programming languages such as C/C++, Python, Java, and more.

• Due to its simplicity, ease of use, and wide platform support, SQLite is often used in mobile apps, desktop applications, web browsers, embedded systems, and other scenarios where a lightweight and embedded database solution is required.
