SQLite

SQLite is a lightweight, open-source, serverless relational database management system (RDBMS) that is widely used for storing and managing structured data locally within applications. It is self-contained, meaning it does not require any separate database server to operate and stores all data in a single cross-platform file.

Features of SQLite:

• Serverless architecture – no separate database server required.
• Zero configuration setup, making it easy to use and deploy.
• Stores entire database in a single file for simplicity and portability.
• Supports standard SQL operations like SELECT, INSERT, UPDATE, DELETE, JOIN, and TRIGGERS.
• ACID compliant ensures reliable transactions and data integrity.
• Extremely lightweight and fast for small to medium-scale applications.

SQLite Usage:

$ sudo su
$ sqlite3 --version
