Creating a database with SQLAlchemy is really easy. SQLAlchemy uses a Declarative method for creating databases. We will write some code to generate the database and then explain how the code works. If you want a way to view your SQLite database, I would recommend the SQLite Manager plugin for Firefox. Here’s some code to create our database tables:

Python

# table_def.py
from sqlalchemy import create_engine, ForeignKey
from sqlalchemy import Column, Date, Integer, String
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import relationship, backref
engine = create_engine('sqlite:///mymusic.db', echo=True)
Base = declarative_base()
class Artist(Base):
    """"""
    __tablename__ = "artists"
    id = Column(Integer, primary_key=True)
    name = Column(String)  
class Album(Base):
    """"""
    __tablename__ = "albums"
    id = Column(Integer, primary_key=True)
    title = Column(String)
    release_date = Column(Date)
    publisher = Column(String)
    media_type = Column(String)
    artist_id = Column(Integer, ForeignKey("artists.id"))
    artist = relationship("Artist", backref=backref("albums", order_by=id))
# create tables
Base.metadata.create_all(engine)

Javascript (babel-node)
