Databases
The subject "Databases" provides a basic introduction to the concepts and applications of databases. It aims to provide participants with a sound understanding of the different types of databases, their benefits and the most commonly used database systems. Here are the main topics covered in this module:
What are databases?
A database is a structured collection of data. There are relational databases, which organize data into tables with relationships, and non-relational databases, which are more flexible and are often used for specific applications such as big data.
Why do you need databases?
Databases offer efficient data management, fast queries and increased data security. They are essential for applications such as customer databases, financial systems and warehouse management.
The most commonly used databases:
MySQL: Open source, widely used for web applications.
PostgreSQL: Advanced functions and SQL support.
Oracle Database: Highly scalable, for large companies.
Microsoft SQL Server: Integrated into the Windows environment.
MongoDB: NoSQL database for unstructured data.
SQLite: Lightweight, ideal for mobile applications.
This module provides a solid foundation for understanding and using databases.
