Define CRUD. Create Read Update Delete
There are seven verb + path combinations that are necessary in a basic Sinatra app in order to provide full CRUD functionality. List each of the seven combinations, and explain what each is for. GET -retrieves info that comes in request POST - creates a new piece of information from the request PUT - updates specific information that is in the request

Introduction to Sinatra

It includes the HTTP verbs and determines what the server will do (i.e. what verb and path, like POST '/')

You can use a hash like :locals {:number => number}

We can use <% = ruby thing you want to show %>

	## 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?

	Primary key is the unique identifier within a table. Foreign key is the unique identifier of another table that has a relationship with the table.
	By default it is the ID. A foreign key will be in the other table and will have a name that starts with the other table name (ex. students) and id.
	So an example would be student_id.
	#### Write down one example of:
	* a `one-to-one `relationship. Person to sandwich. Bicycle to owner. A business to CEO.
