Software Design – Chain of Responsibility Pattern

This episode covers a pattern that is not as well known as some of the recent ones. This time we look at the chain of responsibility pattern. This is also our first foray into the behavioral patterns. These may be techniques you have used without knowing they had a formal name or related pattern. The Chain of Responsibility Pattern Defined As always, we will start with the “Gang of Four” intent to set the stage for our discussion. “Avoid coupling the sender of a request to its receiver by giving more than one object a chance to handle the request. Chain the receiving objects and pass the request along the chain until an object handles it.” This intent is a lengthy one. ... Read more

Software Design – The Proxy Pattern

We continue a look at the structural patterns with a look at the proxy. This is much like the flyweight we reviewed in the last episode. However, it has a different focus. The flyweight can be used to implement a form of proxy but is a solution to a large number of instances where this is a different goal. The Proxy Pattern Defined As always, we will start with the “Gang of Four” intent to set the stage for our discussion. “Provide a surrogate or placeholder for another object to control access to it.” That, once again, provides a short and simple description of our pattern. The proxy saves us from having to instantiate an object before we start using it. The proxy... Read more

Mail Services – Free and Low Cost

This week we look at mailing and communication tools. These mail services have a wide range of features and focal points. That is just part of the reason why we also have a much longer list than typical. These applications are not quick to evaluate. Therefore, you should expect it to take weeks or maybe even months to truly find the best option for you. Common Features Most of the mail services we are looking at in this episode offer a way to build and maintain a list of recipients. There are also templates and automation or scheduling included with most and some simple reports. After that, the features go in different directions as some focus on the CRM side while... Read more
