When you need access to data in a relational database while coding in Python, SQLAlchemy provides an ideal abstraction layer. SQLAlchemy supports several database types. In this course, you'll work with MySQL. You'll start by learning how to construct and invoke select-from-where queries from Python using the SQLAlchemy core API. You'll then use the and_, or_, and not_ functions from the Expressions API, before learning how to alter tables by adding and dropping columns and constraints. Following on, you'll practice deleting data and drop tables from SQLAlchemy. You'll then specify foreign key constraints to define parent-child relationships. To finish off, you'll perform simple select-from-where queries with logical and relational operators from SQLAlchemy, add and drop columns and constraints, and define foreign-key constraints and parent-child relationships.
