Flask SQLAlchemy Tutorial

Flask SQLAlchemy is a versatile database toolkit tailored for Flask applications, leveraging the strengths of SQLAlchemy, a prominent Python Object-Relational Mapping (ORM) library. It simplifies interactions with databases by mapping tables and associations to programming objects, allowing developers to work with databases in an object-oriented manner without needing to write SQL queries. The toolkit supports various database management systems like SQLite, MySQL, and PostgreSQL, enabling tasks such as model definition, query creation, and database migration management. The text elaborates on setting up a Flask application with Flask SQLAlchemy, configuring a SQLite database, defining data models, and managing database migrations using Flask-Migrate. It provides a comprehensive example of creating a CRUD application for managing student data, illustrating the process of setting up routes, creating HTML templates, and handling database operations within a Flask framework. Overall, Flask SQLAlchemy offers a robust and flexible approach to integrating relational databases into Flask applications.
