Which adapter is appropriate for a unified data view from legacy systems for account executives?

The OData 2.0 or 4.0 Adapter for Salesforce Connect is the appropriate choice for providing a unified data view from legacy systems for account executives. This adapter allows Salesforce to integrate with external data sources that are accessible via the OData protocol, which is commonly used for connecting disparate data systems. By using this adapter, you can create a seamless connection to the data stored in legacy systems, allowing account executives to view and interact with this data directly within Salesforce.

This is particularly advantageous because legacy systems often store critical information that may not be present in Salesforce. By utilizing the OData adapter, account executives gain real-time access to this essential data without needing to replicate it in Salesforce, thereby ensuring that they are making informed decisions based on the most current information available.

The other options represent alternative methods for data integration but may not be as suitable for creating a unified data view specifically from legacy systems. The Cross-Org Adapter is more suited for integrating data from different Salesforce orgs rather than legacy systems, while the Google Sheets adapter serves a different purpose by allowing users to fetch data from Google Sheets into Salesforce. A Custom Adapter could be tailored for specific needs but may require additional development and complexity that could be avoided with the standard OData options
