Q & A

What is the main focus of Ahmad Mohamadi's tutorial?

The tutorial focuses on creating a database connection using an API programming approach, including setting up connection strings, models, and handling database migrations.

What is a connection string, and why is it important?

A connection string is a string that specifies information about a data source and the means of connecting to it. It is essential for establishing a connection between the application and the database.

What steps does Ahmad take to set up the connection string in the program?

Ahmad writes a command in the program to initialize the connection string using the 'builder.services' method and specifies the database context name.

How does Ahmad create a model for the database?

He creates a new folder for database models, adds a class named 'Categories', and defines its properties, including an ID and a Name field.

What are migrations in the context of database management?

Migrations are a way to update the database schema incrementally. They allow developers to create, modify, or delete database tables and structures while keeping track of changes.

What command does Ahmad use to create a migration for the 'Categories' model?

Ahmad uses a package manager console command that includes the model's name to generate the migration for the 'Categories' table.

What does Ahmad explain about the primary key in the migration?

He mentions that the primary key for the 'Categories' table will be an ID of type integer, which must have a value, ensuring each record in the table is uniquely identifiable.

What issue does Ahmad encounter while updating the database?

Ahmad realizes he forgot to include the 'TrustServerCertificate' setting in the connection string, which is necessary for SSL connections to the database server.

How does Ahmad conclude his tutorial?

He encourages viewers to ask questions in the comments, to like, share, and subscribe for more tutorials, and wishes them success, promising more content in the future.

What is the significance of organizing database models into folders?

Organizing database models into folders helps maintain clarity and structure in the project, making it easier for developers to navigate and manage their code.
