Building Microservices API in Go - Assignment Solution: Make a Transaction in Bank Account

The video tutorial walks through a solution involving transaction handling in a database. It starts with setting up the domain object and database, followed by executing transactions using Postman. The tutorial includes a code walkthrough from the user to the server side, focusing on transaction validation and handling. It emphasizes ensuring atomicity in transactions and concludes with a preview of the next section on API security.

What is the primary purpose of the transaction domain object?

• To handle error logging

• To store user credentials

• To map transactions with the server side

• To manage user sessions

Which tool is used to demonstrate the working version of the transaction?

• Swagger

• GitHub

• JIRA

• Postman

What happens if an invalid transaction type is provided?

• An error is returned indicating invalid transaction type

• The system defaults to a deposit

• The transaction is processed with a warning

• The transaction is ignored

What is the first step in the code walkthrough from the user side?

• Retrieving account and customer IDs from the URL

• Validating the transaction type

• Updating the transaction table

• Decoding the request

What is the role of the service layer in transaction processing?

• To validate incoming requests and apply business logic

• To handle user authentication

• To manage database connections

• To generate user reports

Why is it important to make transactions atomic in nature?

• To improve transaction speed

• To ensure that if one operation fails, the others do not proceed

• To reduce server load

• To allow multiple users to access the database simultaneously

What is retrieved after committing a transaction?

• User session ID

• Server status

• Transaction ID

• Account password
