Implementation of BSON documents

Consider the following conceptual schema of a sample database that contains information about a bank, the bank$-$accounts administered, the owner's bank account, and the transactions made.

Consider the following domain specification of an application and its conceptual schema:

An airline publishes a PublishedFlights on a recurring basis. The flightNumber uniquely identifies each PublishedFlight for an Airline. Each PublishedFlight has one or more FlightDetail, each from some origin Airport to a destination Airport.

An airport has an IATA $($International Air Transport Association$)$ code and a name. For example, the name of Singapore's airport is Singapore Changi Airport, and its IATA code is SIN.

$\backslash$table$[[$IATA Code,Airport name$],[$SIN$,$Singapore Changi Airport$],[$HLP$,$Halim Perdana Kusuma Airport Jakarta$],[$CKG$,$Chongqing Jiangbei International Airport$],[$KUL$,$Kuala Lumpur International Airport$],[$DMK$,$Don Muang Airport$],[$STV$,$Surat International Airport$]]$

The rest of the values for the other attributes are up to you but must be sensible$.$
