Different Types of Software Design Principles.

By the end of this section, you will have a strong foundation in Software design patterns and principles. Now we may get more than 1 customer detail from those 3 databases against given last name. 6) Email the confirmation to the customerĬustomerDataAccess customerDataAccess = new CustomerDataAccess() Ĭustomer cust = customerDataAccess.GetCustomerDetails(orderToProcess.CustomerId) ĮmailService mailService = new EmailService() The beginner section will help to get insight into software design principles and software Design patterns along with Gang of four design patterns. Scenario: Suppose we have 3 databases (Mortgage Customers, Current Accounts Customers and Savings Account Customers) that provide customer data and we need customer details for given customers last name. TotalMinutes += ds.EstimateDeliveryTimeInMinutes(nextProduct.Key) Also, you are on the border of a principle called Inversion of Control (IoC), which is the practice of using a specific IoC container (Ninject, CastleWinsor, Unity, etc) to resolve your dependencies automatically, whereby you never call the new keyword directly. calculate estimated time of delivery.ĭeliveryService ds = new DeliveryService() įoreach (KeyValuePair nextProduct in productAvailability) SOLID DesignPrinciples SolidPrinciplesHey there, In this video, I tried to explain the SOLID principle by showing the places where and how it can be imple. Reservation.ReserveProduct(nextProductId) ReservationService reservation = new ReservationService() Inventory.CheckStockAvailability(nextProductId) InventoryService inventory = new InventoryService() ĭictionary productAvailability = inventory.CheckStockAvailability(orderToProcess.ProductIds) įoreach (int nextProductId in orderToProcess.ProductIds) 3) Check the item is in stock – inventory PaymentProcessor.DebitAmount(orderToProcess.OrderTotal, cardDetails) PaymentProcessor paymentProcessor = new PaymentProcessor() 2) Check the money has been charged – finance 1) Check the credit card has been accepted.ĬreditCardDataAccess creditCardAccess = new CreditCardDataAccess() ĬreditCard cardDetails = creditCardAccess.GetCreditCardDetails(orderToProcess.CreditCardId) Public bool ProcessOrder(Order orderToProcess) Lets turn our attention to the version 2 of OrderProcesser class that is written by keeping SRP in mind. SmtpClient smtpClient = new SmtpClient("HostName/IPAddress") Īs we can see in the class definition that OrderProcessor has taken more than one responsibility.

Have a look on the code below: public class BankAccount Just because you can, doesn't mean you should.
