Question: need assistance in clear steps using crows feet to create an ERD and entity relationship based on the provided table with the following keys identifying
Table name: CHARTER Database name: Ch03_AviaCo The destinations are indicated by standard three-letter airport codes. For example, STL=St. Louis, MO ATL= Atlanta, GA Table name: AIRCRAFT Table name: MODEL BNA= Nashville, TN AC-TTAF = Aircraft total time, airfame (hours) AC-TTEL = Total time, left engine (hours) AC_TIER = Total time, right engine (hours) In a fully developed system, such attribute values would be updated by application software when the CHARTER table entries were posted. Customers are charged per round-trip mile, using the MOD_CHG_MILE rate. The MOD_SEATS column lists the total number of seats in the airplane, including the pilot and copilot seats. Therefore, a PA31-350 trip that is flown by a pilot and a copilot has eight passenger seats available. Use the database shown in Figure P3.24 to answer Problems 24-31. AviaCo is an aircraft charter company that supplies on-demand charter flight services using a fleet of four aircraft. Aircraft are identified by a unique registration number. Therefore, the aircraft registration number is an appropriate primary key for the AIRCRAFT table
