Python - Flask + MySQL

Flask is a lightweight and flexible web framework written in Python that is used to build web applications. Flask is classified as a “microframework” because it provides the essential tools to create web applications, but does not impose a specific structure or components, giving developers great flexibility and freedom to choose the libraries and tools they want to use in their projects.

On the other hand, MySQL is a widely used open-source relational database management system that allows storing, organizing, and retrieving data efficiently. Developed by Oracle, MySQL offers high speed and reliability, facilitating data management through SQL queries. Its scalability, support for multiple platforms, and ability to integrate with numerous programming languages make it a popular choice for web and enterprise applications. MySQL is highly customizable and has an active developer community that contributes to its continuous improvement.
