Suppose the airline company wants to store following information:
Flight departure/arrival status i.e. either flight departed/arrived late or in time.
Flight type i.e. either flight is connected or direct.
For storing the departure/arrival status a new table with the name “FlightADStatus” is created with following structure and data:
StatusID StatusName Description
01 OnTime This status is set if flight departs or arrives as per schedule
02 Late This status is set when the flight departs/arrives behind the specified schedule
03 NotDecided This status is set when the flight is schedule first time. After the flight departs/arrives, the status is modified
For flight types, a master table with the name “Flight Type” is also created with following structure and data:
FTypeID FTypeName Description
A flight is direct when it moves directly from source to destination location
02 Connected A flight is connected with moves indirectly from sourceto destination involving multiple legs.
For your convenience the modified ERD (with more abstraction level) is given below:

“Total number of direct flights that departed late with in month of November”
“Total number of connected flights that departed in time with in month of October”
“Total number of direct flights that departed in time with in month of October”
For this purpose, organization defines a new business process named “Flight_Status_Aggregate”.
Question: [Marks 20]

You are required to consider the ER Model given in this assignment and ignore the one developed by you in last assignments.
Be specific and provide to the point answer. Avoid irrelevant details and definitions.
