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.

Note the following within the project:

- The project has a model made up of `SchoolContext.cs` in the `Models/Data` directory as well as `Department.cs`, `Instructor.cs`, and `Student.cs` located in `Models/Entities` directory.

- A migration named `InitialMigration` exists in the project. This migration reflects the initial state of the models.

# Challenge requirements
- Rename the `Title` property of the `Department` entity to `Name`.

- Delete the `HOD` property of the `Department` entity.

- Create migrations to reflect these changes.

- Generate a SQL script for pushing only the changes made to the `Department` entity to a live database. Save them in a directory named `Scripts`.

> **Note:** From the terminal window, we can verify the file structure and content 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.

Good luck!

Challenge yourself by performing migrations on a school database.
