.NET Core Microservices - Entity Models for Shopping Cart API

The video tutorial explains the structure of a shopping cart system, focusing on creating tables for headers, product details, and handling product information using microservices. It discusses the challenges of retrieving product details from a product API and suggests maintaining a local copy to improve efficiency. The tutorial also covers scenarios of price updates in microservices, using flight booking as an example. It guides viewers through creating models in a solution explorer, defining product and header models, and building a card details model with primary and foreign keys.

• It leads to data redundancy.

What is a common scenario where price updates are handled similarly to the shopping cart API?

• Movie ticket booking

• Hotel reservations

• Flight booking websites

• Online grocery shopping

What is the purpose of copying the product model from the Product API?

• To allow automatic ID generation

• To improve the speed of the Product API

• To ensure consistency in product details

• To reduce the size of the database

How is the product ID handled in the shopping cart API?

• It is generated using a random number.

What is the primary key in the card header model?

• Product ID

• User ID

• Coupon Code

• Card Header ID

How are relationships between card details and card header maintained?

• Using a shared primary key

• Using a common index
