In this article, we will learn what Factory Design Pattern is and why we use Factory Design Pattern, with a real world example. We will see what type of problems are resolved using Factory Design Pattern. Now-a-days, if we create a software, it gets outdated soon because of the ...

Since it is a broader, or a super-set, of the Factory Pattern, we will try to explain this with an example of the Factory Pattern and try to move on to the Abstract factory. So let's start with the Factory Pattern example.A real-world example for Factory PatternSuppose your company ...
Factory Pattern Conclusion Doug Purdy Microsoft Corporation February 2002 Summary:Discusses the Factory creational pattern that uses a specialized object solely to create other objects, much like a real-world factory. The logical and physical models of this pattern are examined, as is one use of thi...

Factory Method is a creational design pattern used to create concrete implementations of a common interface. It separates the process of creating an object from the code that depends on the interface of the object. For example, an application requires an object with a specific interface to perform...
The Simple Factory isn’t actually a Design Pattern; it’s more of a programming idiom. But it is commonly used, so we’ll give it a Head First Pattern Honorable Mention. Some developers do mistake this idiom for the “Factory Pattern,” so the next time there is an awkward silence bet...
For example, the Web Service Software Factory is designed to provide guidance and enhanced tools for building Web services using either ASMX or Windows Communication Foundation (WCF). Instead of starting with the somewhat low-level Web service features exposed by the WCF libraries, the Web...
Generally speaking, a software factory is installed to extend your development environment, adding guidance-related tools and resources. For example, a software factory might include solution templates that make it easier to start a new application. And it might provide wizards and designe...
