5. What is GraphQL?
● GraphQL is an open-source query language for Rest API's and it is developed by Facebook in
2012 before releasing publicly in 2015. GraphQL allows you to send the query to your API and
get the required data.
● REST APIs are powerful and follow a resource-oriented and well-structured approach.
However, when the data is complex and it is not possible to fetch all the data within a single
request as it involved various operations and routes get more complex. GraphQL is very
useful in such cases and structures data in the form of a graph with its powerful query syntax
for traversing, retrieving, and modifying data.
● GraphQL is capable of aggregating the data, returns predictable data to the clients.

6. What is Anypoint DataGraph?
Anypoint DataGraph is a component of Anypoint Platform which allows you to unify the multiple
APIs into a single data service. Anypoint DataGraph is the unified platform for APIs to design,
develop and manage. It allows to discover, manage or serve the data from multiple apis using
single DataGraph request.
This reduces a lot of efforts for developers to call multiple APIs and aggregate the response. With
Anypoint DataGraph, you can request only data you want, no more or no less.

7. Anypoint DataGraph Advantages
Unify the multiple APIs into the single data service. With Anypoint DataGraph, you can
serve data from multiple underlying APIs within a single request without writing any code.
Consume the data from multiple APIs using a single request.
Developer doesn't have to write the code to parse the data from multiple APIs.
Anypoint DataGraph is managed service, no maintenance or patching for IT.
Request the data you want, no more no less.
Reduce development and maintenance efforts.
Anypoint DataGraph is a managed service and no need to worry about underlying
infrastructure and maintenance.

8. Use Case 1
Let's consider the scenario, you have a Rest API that returns 10 fields in response but web
application requires only 7 fields whereas mobile application requires only 4 fields. In such cases,
DataGraph is one of the most optimal options where the client can pass whatever data required
as an input request, and DataGraph will return the required fields to the Web Application and
Mobile Application. Below is the illustration of Use Case 1.

9. Use Case 2
Let's consider the scenario where you have to call multiple rest endpoints or want to fetch data
from multiple rest endpoints and each APIs will respond with JSON payload. GraphQL will
aggregate all the responses and send back the required data to the client. Below is the
illustration of Use Case 2.

10. Use Case 3
Let's consider the scenario where you have to call multiple Rest APIs to fetch account details
and related customer details. Customer details and Account details exist in different APIs.
CustomerId is the primary key in customers apis and accountId is the primary key in accounts
apis. Also, customerId is foreign key in accounts apis. Below is the illustration of Use Case 3.

Monitor or Trace or Measure the API Performance
With a single UI, it is possible to trace the query response time and logs, ensuring to
measure the performance of query or apis request and meets expected SLA’s.
Authentication Mechanism
DataGraph support below list of Authentication mechanism while calling underlying APIs
Basic Authentication
Client Id Enforcement via Headers
Client Id Enforcement via Query Params
Custom (Add Custom headers or Query Params)
No Auth
Pass-through Authentication
Oauth 2.0 Client Credentials
