Course Description

Course description

In this course you’ll learn some of the basics of object relational mapping systems and how they overcome some of the problems when working with relational data in an object based application. You’ll also see how entity objects are a big improvement over generic data objects, such as the data set and the data tables provided by ADO.NET. Then you’ll learn specifically about the Entity Framework, Microsoft’s ORM technology and why it is a compelling data access technology in the .NET development space. Big spoiler, it’s not just because Microsoft has made Entity Framework their core data access strategy. You’ll see Entity Framework in action to build a simple but powerful data access application as well as some of the APIs and tools it provides.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.


This course assumes that you are experienced with relational database design and programming concepts. Entity Framework is all about data access, and the course doesn’t spend any time on data fundamentals. You’ll also need a good understanding of object-oriented programming in C#, so that you know how to use the entity data objects that Entity Framework generates from your data model. You’ll also need to have a working knowledge of Language INtegrated Queries (LINQ) in C#. The course uses Entity Framework with various SQL Server databases, so you should know enough about SQL Server to know how to perform various tasks and be able to connect to a database. But you don’t need deep knowledge of SQL Server to use Entity Framework productively.
