Three object are :Ship__c,port__c.shipment__c
ship__c has lookup with port{shipToport__c}
shipment__c  has lookup with port as well as ship portLookupD__c & shipLookupD__c respectively.

Requirement:
1.Create ship1 record has five shipment1,.....shipment5.
2.when ship updating shipToport__c value
3.copied all shipment of ship [from ship to port] 
as well as delete shipment only from ship.
 

 Create 3 objects Ships, Ports, and Shipment. Ship object has 4 fields Name, Number of Shipments, Lookup to Ship, Lookup to Prots. Ports has 3 fields, name of the port, number of shipments, Status. Shipment object has lookup to Ships as well as ports. When a Ship is docked to a port, the status of the port changes from ‘idle’ to ‘engaged’.

Assume that multiple ships have docked the port and write a code which copies all the shipments from docked ships to the port. 

Create 3 objects Airplanes, Schedules, and Flights. Airplane object has 2 fields Name of airplane, number of seats. Schedules object has 4 fields, start date, End date, Post Date (formula field Start Date minus 30- days) and lookup to Airplane object. An Airplane can have multiple schedules. Flight object has lookup to schedules as well as Airplane and 2 additional fields as Flight start date and flight end date.

Write a code that will run every day on Schedule and when the Post Date is less than or equal to today, create a record of flight object.

Create 3 objects Airplanes, Schedules, and Flights. Airplane object has 2 fields Name of airplane, number of seats. Schedules object has 4 fields, start date, End date, Post Date (formula field Start Date minus 30- days) and lookup to Airplane object. An Airplane can have multiple schedules. Flight object has lookup to schedules as well as Airplane and 2 additional fields as Flight start date and flight end date.

Write a code that will run every day on Schedule and when the Post Date is less than or equal to today, create a record of flight object.
