Flask SQLAlchemy
Flask SQLAlchemy is an ORM tool which establishes the relationship between the objects and the tables of the relational databases.
The mapping between the both is important because the python is capable of storing the data in the form of objects whereas the database stores the data in the form of relational tables, i.e. the collection of rows and columns.
The object-relational mapping is the technique of storing python objects into the database tables without writing the raw SQL queries.
