CreateSchoolTablesInOutputDir

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.

# Challenge requirements

Perform the following operations using data annotations:

* Map the `Title` property of the `Department` entity to the `Name` column of the `Departments` table.

* Add a “Head of Department” comment to the `HOD` property of the `Department` entity.

Perform the following operations using the fluent API:

* Map the `Instructor` entity to the `Teachers` table.

* Map the relationship between an `Instructor` and the `Department` using the `DepartmentCode` property as the foreign key of the relationship.

> **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!
