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.

## Overview

In this lesson, we review global query filters.

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

## Global query filters

Global query filters enable us to apply query predicates to entities in the `OnModelCreating` method. EF Core then applies the predicate automatically to any LINQ queries involving those entities directly or indirectly through navigation properties. We’ll demonstrate them using the C# console project below:
