Object Relational Mappers

What can be the use of object relational mappers?

If we do a lot of database work, we might want to consider checking out an Object Relational Mapper (ORM). An Object Relational Mapper allows us to work with the database without using SQL itself. Some developers call it more “Pythonic” since it’s not a mix of Python code and SQL. The most popular ORM in Python is SQLAlchemy.
