1. Discuss the significance of the primary key and why it is particularly important to know about when creating a table.Please use one example we mentioned in class about the column name that we used as primary key.

2. What is a relational database and what specifications must it meet? (Hint: I used the example of connecting to the parent table from the child table using what kind of key? From which table's (primary or foreign key) connecting to which table's (parent or child?) primary or foreign key?)
