Design Microservices Architecture with Patterns and Principles - Graph: QL Core Concepts, Schemas, Queries, Mutations, a

The video tutorial introduces GraphQL, focusing on its key components: Sikkimas, queries, mutations, and resolvers. It explains how developers can use GraphQL to define data structures and handle client requests efficiently. The tutorial contrasts GraphQL with REST API, highlighting the benefits of sending a single query to retrieve complex data structures. It also covers how clients can specify their data needs, and how the server responds with a structured JSON object. The video emphasizes the efficiency and flexibility of GraphQL in handling API requests.

What is a Sikkima in GraphQL?

• A type of query

• A function attached to fields

• An operation to modify data

• A description of possible data clients can query

What role does a resolver play in GraphQL?

• It describes the data clients can query

• It produces values during query execution

• It modifies existing data

• It defines the structure of a query

How is a GraphQL query structured?

• By using only predefined types

• By sending multiple queries to the server

• By defining types and fields, and providing functions for each field

• By modifying existing data on the server

What is a key advantage of using GraphQL over REST APIs?

• GraphQL requires multiple requests for data

• GraphQL is slower than REST APIs

• GraphQL can retrieve enriched data in a single request

• GraphQL does not support nested data structures

How does the server response structure in GraphQL relate to the query?

• It is always a flat structure

• It mirrors the nested structure defined in the query

• It follows a random structure

• It is completely different from the query structure
