The video tutorial explains the concept of seeding data into a database using Entity Framework. It covers the process of overriding methods in the DB context to insert default data, focusing on seeding countries and hotels. The tutorial also demonstrates how to perform migrations and verify data insertion, ensuring that the database is correctly populated with initial data for testing and development purposes.

What is the primary purpose of database seeding?

• To update the database schema

• To add default data when the application is first run

• To delete existing data in the database

• To backup the database

Which method is commonly overridden in the DB context for seeding?

• OnConfiguring

• OnModelCreating

• OnDatabaseError

• OnSavingChanges

Why is it important to define primary keys correctly when seeding data?

• To allow data to be exported

• To improve query performance

• To prevent duplicate records

• To ensure data is encrypted

What is the first entity seeded in the example provided?

• Tourist Attraction

• City

• Country

• Hotel

What is a potential issue if two countries are seeded with the same ID?

• The database will encrypt the data

• The application will run faster

• Entity Framework will throw an error

• The data will be backed up

What is the significance of the order in which countries and hotels are seeded?

• Both must be seeded simultaneously

• The order does not matter

• Countries must be seeded before hotels

• Hotels must be seeded before countries

What is the purpose of performing a migration after seeding data?

• To apply changes to the database schema

• To export the data to a file

• To delete the seeded data

• To encrypt the database
