MySQL Database: An Overview

MySQL is a widely used open-source relational database management system (RDBMS) designed for efficient data storage, retrieval, and management. It operates on a client-server architecture and uses Structured Query Language (SQL) to interact with data.


1. Key Features of MySQL

- Relational Database System – Organizes data into structured tables with rows and columns.

- Open-Source & Free – Available under the GNU General Public License (GPL).

- High Performance & Scalability – Efficiently handles small to large-scale datasets.

- Cross-Platform Compatibility – Runs on Windows, Linux, macOS, and cloud platforms.

- Security Features – Supports authentication, encryption, and role-based access control.

- Replication & Clustering – Enables database mirroring for high availability and backups.


2. MySQL Architecture

MySQL follows a client-server model, composed of:


- Client Applications – Send SQL queries to the MySQL server.

- MySQL Server – Processes queries and manages database operations.

- Storage Engine – Determines how data is stored and retrieved (e.g., InnoDB, MyISAM).
