What implementation ensures Salesforce users can create, read, update, and delete data sourced from an external data warehouse?

The implementation that ensures Salesforce users can create, read, update, and delete data sourced from an external data warehouse is effectively achieved through the use of a canvas application for external access.

Canvas applications allow for a seamless integration of external data and functionalities within the Salesforce interface. By embedding a canvas app, organizations can provide users with the ability to interact directly with data residing in an external data warehouse as if it were part of Salesforce itself. This integration allows for full CRUD (Create, Read, Update, Delete) operations on the data, enabling users to work efficiently while utilizing the familiar Salesforce environment.

This approach not only enhances user experience but also leverages the robust capabilities of Salesforce in conjunction with external systems, ensuring that users have access to the most current and relevant data from the external source without the need for complex data migrations or duplications.

In contrast, the other options may not fully address the requirement for extensive data manipulation directly within the Salesforce ecosystem. For instance, utilizing Lightning Connect can enhance data connectivity but might require additional custom development to achieve full CRUD capabilities. Using a third-party JavaScript library could introduce challenges with interoperability and maintaining secure connections. Employing AppExchange tools may provide solutions for specific tasks, but generally, these tools are not designed for
