Database

Databases manage large data volumes with scalability, speed, and flexibility. Key systems include:

• MySql
• PostgreSQL
• MongoDB

They facilitate efficient CRUD operations and transactional processing (OLTP) structured by schema that organizes data into tables and relationships.

Key Features

• structured data: Organized for efficient CRUD operations, allowing reliable access.
• Relational Database: Use SQL to manage data in tables with relationships expressed through foreign keys and joins, minimizing redundancy.

Structure

• Data is organized into tables (like spreadsheets) with columns (fields) and rows (records), enabling efficient storage and retrieval.

Flexibility

• Databases have a flexible schema that adapts to evolving requirements, unlike static solutions like spreadsheets.
