The Role of Abstract Classes in Real Life Software Development Service

The role and significance of Object Oriented Programming approach is highly suggested across software development consulting services. In fact, most open source software follow Object Oriented approach that offers economical and reliable software development solutions worldwide.

One of the many features that empower Object Oriented approach is inheritance. Any Software development service implements abstract classes to implement this genuinely valuable feature of inheritance to build a robust, user friendly and ever-expanding programming code library.

Definition of Abstract Base Class

Abstract base class, also known as ABC represents an abstract concept that captures the most basic features of a general category to form it as base class and facilitate inheritance.

For example, if you asked a carpenter to build furniture, he would need more information on the kind of furniture you would like to be built or repaired. You could be asking to build a dining table, or a swinging chair or a double bed. Just from the term furniture, he cannot commit whether he would be able to do the job as he may be specializing in just chairs and not a double bed or a table. In other words, the abstract base class would be furniture and certain classes would be derived from this base class defining a table or a chair or a bed and so on. An abstract class has one or more pure virtual member functions that cannot be implemented. In simpler terms, an abstract class does not have objects or instances.

When do you create abstract base classes?

It is usual for any software development service to create abstract base classes when beginning with a software development project. These classes are created when the software development service identifies some common features shared by all the objects concerned with projects.

Software development consulting services recommend writing of an interface when the programmer anticipates different implementation of each feature for different objects and the implementation is to be done by the third party vendor.
