:Project Description

Consider the following set of requirements for an airline reservation system.

Information on airplanes and airplane types are also kept. For each airplane Its type is defined by the name, the total number of seats, and the company that produces it. Specific airplane types can land at specific airports.

For each airport we need to know the name, the city, the state, and the code of it. Each flight has information about the airline, the number and the weekdays it operates. It also has fares, with code number, amount, and restrictions.

A flight has several flight legs (for example Riyadh-New York have two legs, Riyadh-London and London-New York, it means you are flying from Riyadh to New York via London), where each flight leg has a departer and arrival airport and scheduled departure and arrival times.

Each airplane is assigned to a leg instance, which is a particular occurrence of a flight leg on a particular date. Each leg instance arrives to and departs from airport at specific arrival and departure times. Finally, for each leg instance we can make reservations of seats, based on the customers name and customer phone number.

Phase 1: Conceptual Data Model - Read the project specification, carefully, and draw a conceptual design data model to accurately represent this set of requirements. Specify any additional assumptions that you are making. most notably you should use any tool (Data Modeling Tool) to draw the diagram.
