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
Each entity type in the model has a set of properties. In this lesson, we’ll review how to configure entity properties using data annotations or the fluent API. In other words, we’ll learn how to configure the property to column mappings.

> **Note:** The commands in this lesson generate code and files. Through the terminal, we can navigate to these files by using relevant Linux commands such as `ls` to view a list of files and directories, `cd` to change directories, and `cat` to view file contents. A SPA widget showing the updated project with the generated files is also available. Also, note that EF Core uses a timestamp within the generated file names. We represent these names with `xxx`.

## Default conventions
To demonstrate, we’ll work with the C# console app project below:
