Пожалуйста, проверьте, соответствует ли мой код этим требованиям. Это CRM-система.
Data Customer Information • Forename • Surname • Date of Birth Vehicle Information • Manufacturer • Model • Registration number • Registration date • Engine size (in cc) • Owner • InteriorColour (Car only) • Has Helmet Storage (Motorcycle only) Required Relationships • Customers can have 1 to many vehicles. • Vehicle must have exactly one owner. • Vehicle type cannot be changed once it is created. Reports • We will require reports to be designed to contain: o All known customers and any vehicles they own. o All customers between the age of 20 and 30. o All Vehicles registered before 1st January 2010. o All Vehicles with an engine size over 1100. Expected demonstrable skills • Good understanding of C#. • Good understanding of Object Orientated (OO) principles. • Good understanding of relational data principles. • Reusable code – low coupling, high cohesion
