Developer

Design

In creation of the internship_2_career database schema, the entities must be created in the order listed below. The creation of the tables is broken down into four groups. Group 1 must be created first then group 2 and so on. The arrows in the UML diagram below don't necessarily show relationships rather just the order of creation. Ordering the creation is critical because of the relationships between the tables. If for instance you try to create a table in the third or fourth group prior to the creation of a related table in the first or second group mysql will give you an error and the tables will relate.
