Developers are spoilt for choices from the various software development methodologies available. Most of the methodologies fall can be categorized as either a waterfall, iterative or continuous model. A waterfall methodology follows a fixed sequence in implementation. Stages of development are defined in a rigid, sequential manner. This model was… Continue reading

Polymorphism , the third pillar of object-oriented programming, is closely related to inheritance. The prefix poly means many; morph means form. Thus, polymorphism refers to the ability of a single type or class to take many forms. There are times that you will know you have a collection of a… Continue reading
The second pillar, specialization, is implemented in C# by declaring that a new class derives from an existing class. When you do so, the specialized class inherits the characteristics of the more general class. The specialized class is called a derived class, while the more general class is known as… Continue reading
The first pillar of object-oriented programming is encapsulation. The idea behind encapsulation is that you want to keep each type or class discreet and self-contained, so you can change the implementation of one class without affecting any other class. A class that provides a method that other classes can use… Continue reading
Object-oriented programming is built on three sturdy pillars: encapsulation, specialization, and polymorphism. Encapsulation: Each class should be fully encapsulated, that is, it should fully define the state and responsibilities of that type. For example, if you create an Employee object, that Employee object should fully define all there is to… Continue reading
The figure “Agile and traditional SDLC” points out some of the main differences. If you have worked on both these, you can point out more differences.
