Object-Oriented Programming Fundamentals in C#

Building Entity Classes - Part 1
Welcome back to Object-Oriented Programming Fundamentals in C#. My name is Deborah Kurata and this module demonstrates how to build the entity classes identified in the prior module. These are the classes we identified so far in this course. Customer, product, order, order item. This module provides step by step demonstrations showing you how to create and test one of these entity classes. The other classes are then created using the same techniques, but before we can build the classes, we need to lay out the structure of the application.

Building Entity Classes - Part 2
Welcome back to Object-Oriented Programming Fundamentals in C#. My name is Deborah Kurata and this module continues the process of building entity classes. In the last module, we created the business layer component, added the customer class, and added properties to that class. We then added an automated code test to test the logic in one of the properties. But what about the methods? We defined the validate, retrieve, and save methods. This module demonstrates adding methods to the customer class including special methods called constructors. We'll then use what we've learned so far in this course to create the product, order, and order item classes.

Final Words and Next Steps
As we have seen, C# is a modern, general purpose, object-oriented programming language. Now that you know more about object-oriented programming concepts you can better leverage the features of C# to build well-crafted and testable applications. Welcome back to Object-Oriented Programming in C#. My name is Deborah Kurata and the final words in this course include a brief summary and a look at next steps you may want to take to further your study.
