The messages are of two types. Normal Priority High Priority The Normal Priority messages are to be processed by Logger class and High Priority messages by Emailer class. You have to make the design in such a way that the Logic class need not think about right handler of the message. It will just send the message. How the design will proceed? Definition GoF Definition: "Avoid coupling the sender of a request to its receiver by giving more than one object a chance to handle the request. HandleMessage(message); } } We can see from the above code that the Logic class has a property of type IReceiver.
The sender does not think about the right receiver. Instead it will pass the request and the appropriate receiver should process it. The above example can be written using a list of receivers in the Logic class with a Boolean property mentioning whether the message is processed or not. Comparing Observer and Chain of Responsibility In the case of Observer pattern all the registered receivers will get the request. Each of the receivers is interested in processing it. But in chain of responsibility the request is passed until it is not processed.
Even though Vistor Pattern is an Object Oriented Extension we can use the concept in database too. Let us explore this with a simple example. We are having a table to store Transaction having Quantity and Price. The table is populated with data. We need to get the TotalPrice which is Quantity multiplied by Price. Without doing any data updating we can use Computed Column as shown below to achieve the results. The result is shown below: Design Patterns in C# The above result is achieved without doing any data updating.
