Mechanic number, airport name, and skill number are all unique fields. Size is an airport’s size in acres. Skill Category is a skill’s category, such as an engine skill, wing skill, tire skill, etc. Year Qualified is the year that a mechanic first qualified in a particular skill; Proficiency Rating is the mechanic’s proficiency rating in a particular skill.

We now add the following tables to the database that record data about airplanes and maintenance performed on them. A maintenance event is a specific maintenance activity performed on an airplane.
