We need to design a database to save information about Airline Company Database. Here is the gathered information: -An airplane has a registration number, a type and localization. Every airplane type is described by his name (Boeing 747, Airbus A340...), his weight, his capacity and his action zone. - A technician of the company is characterized by a name, an identifier (ID), an address, a phone number, a salary, and he is expert on one type of airplane or more during a given period (start date and end date). - A pilot has the same attributes as the technician, in addition to number of years of experience. - Every airplane must pass a number of functional tests. - Every test has a number as identifier, a name and a value. We need to save the date and the state of every test. - Every flight is commanded by only one pilot and concerns a specific airplane. A flight has a departure city, an arrival city, a departure time, and an arrival time.

We need to design a database to save information about Airline Company Database. Here is the gathered
information:
- An airplane has a registration number, a type and localization. Every airplane type is described by his
name (Boeing 747, Airbus A340 ...), his weight, his capacity and his action zone.
- A technician of the company is characterized by a name, an identifier (ID), an address, a phone number,
a salary, and he is expert on one type of airplane or more during a given period (start date and end date).
- A pilot has the same attributes as the technician, in addition to number of years of experience.
- Every airplane must pass a number of functional tests.
- Every test has a number as identifier, a name and a value. We need to save the date and the state of every
test.
- Every flight is commanded by only one pilot and concerns a specific airplane. A flight has a departure
city, an arrival city, a departure time, and an arrival time.
