This course introduces Entity Framework Core for data access and object-relational mapping. Entity Framework Core provides benefits such as the ability to work with databases using .NET objects without the concern for underlying database tables. This leads to less code for data access and improved performance. 

You’ll begin with the workflows of Entity Framework Core—reverse engineering and migrations. Next, you’ll learn model configuration and relationships. Then, you’ll cover various methods for querying and saving data. You’ll also learn about change tracking and its relationship with queries. Finally, you’ll learn about logging and testing.

Entity Framework Core simplifies app development. By the end of this course, you’ll be able to improve code maintainability and concentrate on business logic by generating SQL, materializing results, and performing other tasks. You’ll have a good understanding of Entity Framework Core, which will improve your productivity and efficiency on your development journey.

Using Entity Framework Core for Data Access & Relational Mapping

## Overview

In this lesson, we’ll review the following topics:

* Raw SQL queries
* Split queries

> **Note:** The outputs from the projects in this lesson contain the results of sample codes and logs of the translated SQL queries used.

## Raw SQL queries
Raw SQL queries provide a powerful medium to interact with relational databases. They are beneficial when we cannot express the desired query with LINQ.

We’ll demonstrate them using the C# console project below:
