SQLite Course

SQLite is a popular open-source relational database management system (RDBMS) that is known for its simplicity, lightweight nature, and self-contained design. Unlike other database management systems, SQLite doesn't have a separate server process and operates directly on disk files. Here are some key aspects to know about SQLite:

1. Embedded Database: SQLite is designed as an embedded database engine, which means it is integrated into the applications that use it. It is suitable for scenarios where an application needs a local database without the need for a separate server process. SQLite libraries can be embedded in various programming languages, making it a versatile choice for application development.

2. Serverless Architecture: With SQLite, there is no need to install and configure a separate database server. The database resides in a single file on the disk, which can be accessed by the application. This simplicity and self-contained nature make it easy to deploy and manage.

3. ACID Compliance: SQLite ensures the ACID properties (Atomicity, Consistency, Isolation, Durability) for transactions. It supports transactional operations and provides mechanisms for data integrity and recovery.

4. SQL Support: SQLite supports a subset of the SQL language, providing a familiar interface for managing relational databases. It includes features like creating tables, inserting, updating, and deleting data, querying with SQL statements, and defining relationships between tables using foreign keys.

5. Cross-Platform Compatibility: SQLite is cross-platform and works on various operating systems, including Windows, macOS, Linux, and mobile platforms like Android and iOS. This makes it a versatile choice for application development across different environments.

6. Small Footprint: SQLite is designed to have a small memory and storage footprint. The database engine itself is lightweight, making it suitable for resource-constrained environments such as embedded systems or mobile devices.

7. Use Cases: SQLite is commonly used in applications that require a local database, such as mobile apps, desktop applications, embedded systems, and small-scale web applications. It is especially useful for scenarios where simplicity, portability, and ease of deployment are essential.
