Exam PL-600 topic 2 question 16 discussion

HOTSPOT -
A company plans to create a Power Platform solution that integrates with Dynamics 365 Sales.
The solution must meet the following requirements:
✑ Connect directly with a Microsoft Azure SQL database as an external data source at run time where specific data is available in the Dynamics 365 Sales solution without the need for data replication.
✑ An external system needs to send data to the company's Dynamics 365 Sales solution.
You need to recommend the most suitable solution to integrate Dynamics 365 Sales with both systems.

Hot Area:

Suggested Answer:
Box 1: Use Virtual tables -
A virtual entity is a custom entity in Dynamics 365 Customer Engagement (on-premises) that has fields containing data from an external data source. Virtual entities appear in your app to users as regular entity records, but contain data that is sourced from an external database, such as an Azure SQL Database.
Records based on virtual entities are available in all clients including custom clients developed using the Dynamics 365 Customer Engagement Web Services.
Box 2: Use Dynamics 365 Web API.
Dynamics 365 Web Services API: Many times, straight database-to-database integrations aren't a possibility. In these cases, the development of a solution may depend on utilization of the Dynamics 365 Customer Engagement web services API (Application Programming Interface).
