How to connect SQLALCHEMY to Postgresql Server Database In Telugu - Python Web Development Flask

SQLAlchemy is a powerful Object Relational Mapper (ORM) library for Python that streamlines the interaction between Python code and relational databases. It provides an efficient and flexible way to query and manipulate data while abstracting the underlying database system. ORM is a programming technique that maps database tables to Python classes and table records to class instances. This allows developers to work with database records using familiar object-oriented concepts, making the interaction with databases more intuitive and efficient. Sqlite3 database connection: app.config['SQLALCHEMY_DATABASE_URI']='sqlite:///db.sqlite3' Postgresql database connection: app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql://myuser:mypassword@localhost/mydatabase' mysql database connection: app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql+mysqlconnector://myuser:mypassword@localhost/mydatabase' Sqlserver or mssql database connection: app.config['SQLALCHEMY_DATABASE_URI'] = 'mssql+pyodbc://myuser:mypassword@localhost/mydatabase?driver=ODBC+Driver+17+for+SQL+Server'SQLAlchemy is a powerful Object Relational Mapper (ORM) library for Python that streamlines the interaction between Python code and relational databases.
