Question 1

A healthcare provider needs to display patient appointment data from an external Electronic Health Record (EHR) system on the Contact page in Salesforce. Due to HIPAA compliance, the patient's appointment data must not be stored (replicated) in Salesforce. The data must be retrieved in real-time when a user views a Contact record. The EHR system exposes this data via a standard OData 4.0 compliant REST API. Which integration solution should the architect recommend?

```mermaid
graph TD
User[Healthcare Agent] -- views --> SF_Contact[Salesforce Contact Page]
SF_Contact -- reads from --> External_Object[External Object: Appointments]
External_Object -- real-time query via OData --> Salesforce_Connect[Salesforce Connect]
Salesforce_Connect -- secure callout --> EHR_API[EHR OData 4.0 API]
EHR_API -- returns data --> Salesforce_Connect
Salesforce_Connect -- presents data in --> External_Object
```

Accepted Answer

Salesforce Connect using the OData 4.0 adapter to create an External Object.

Answer

A custom Lightning Web Component that performs an Apex callout to the EHR's REST API on page load.

Answer

A batch data synchronization process using an ETL tool to replicate EHR data into a custom object.

Answer

Publishing Platform Events from the EHR system to a trigger in Salesforce that stores the data in a Big Object.

Question 2

A company is designing a Lightning Web Component (LWC) to display transactions aggregated from different sources. Their current system landscape is as follows:1. Transactions are created at any time through their various on-premise and cloud-based systems.2. All necessary transactions are replicated to a custom Transaction object in Salesforce. It is updated periodically so it only has a subset of the necessary transactions between updates.3. Middleware supports publish-subscribe interactions and provides RESTful Enterprise APIs that can retrieve transactions from on-premise and cloud-based systems.The company wants to address a usability concern regarding incomplete data displayed on the LWC component.What should the integration architect specify so the LWC will be able to display all the required transactions?

Accepted Answer

Use the Continuation class to call the Enterprise APIs and then process the response in a callback method.

Answer

Publish a Platform Event, have the middleware subscribe and update the custom object on receipt of Platform Event.

Answer

Call the Enterprise APIs directly from the LWC's JavaScript code and redisplay the LWC on receipt of the API response.

Answer

Let the Lightning Data Service with an @wire adapter display new values when the custom object records change.
