Ultimate ASP.NET 5 Web API Development Guide - Implement Paging

The video tutorial covers the implementation of paging in API development. It begins with an introduction to the importance of paging for managing large datasets. The tutorial then guides through creating query parameters and a paged result class to handle API responses efficiently. It explains modifying the repository to support paged results and optimizing mapping operations using generics. The video also demonstrates implementing paging logic in the repository and concludes with testing and debugging the implementation using Postman.

Why is paging important in API development?

• To manage large datasets efficiently.

• To enhance the security of the API.

• To increase the speed of data processing.

• To reduce the number of API endpoints.

What is the default page size set in the Query Parameters class?

• 10

• 15

• 20

• 25

What is the purpose of introducing generics in the repository?

• To reduce the size of the database.

• To increase the number of API calls.

• To handle multiple data types efficiently.

• To simplify the code structure.

How does mapping at the database level optimize queries?

• By eliminating the need for SQL queries.

• By selecting only necessary columns.

• By reducing the number of rows processed.

• By increasing the number of columns retrieved.

What is the advantage of using DTOs in paging?

• They simplify data transfer between client and server.

• They increase the size of the data payload.

• They allow for more complex queries.

• They reduce the number of API endpoints.

What is the role of the 'skip' method in paging?

• To specify the starting point for record retrieval.

• To filter records based on a condition.

• To limit the number of records returned.

• To sort the records in ascending order.

What tool is used to test the paging implementation?

• SoapUI

• JMeter

• Postman

• Swagger

What happens if the start index is set beyond the available records?

• The first page of records is returned.

• The last page of records is returned.

• An error is returned.

• No records are returned.

How can you specify query parameters in Postman?

• By using the authorization tab.

• By using the body tab.

• By using the headers tab.

• By using the params tab.

What should be done if an ambiguous match exception occurs?

• Rename conflicting routes.

• Add more query parameters.

• Increase the timeout settings.

• Reduce the number of API calls.
