Models, Databases, Relationships in Rails

What is the difference between a primary key and a foreign key? Where would we find a primary key? What would it be called by default? Where would we find a foreign key? What is the naming convention for a foreign key?

A primary key is the primary unique identifier of a table, a foreign key is the primary key of another table that serves as as the relationship between the two tables. A primary key is generally named id, a foreign key is named othertable_id whith the name of the table the foriegn key links to followed by id.

Write down one example of:

• a one-to-one relationship.
  • Each car has one license plate and each license plate belongs to one car
• a one-to-many relationship.
  • A School has many students but each student has only one school
• a many-to-many relationship.
