Which feature allows for data from legacy systems to be seamlessly merged into Salesforce?

The correct answer highlights the use of Salesforce Connect, which allows for real-time access to external data sources without having to copy or upload the data into Salesforce. This is particularly beneficial for organizations that have legacy systems holding important data they wish to access alongside their Salesforce data. By using Salesforce Connect, these organizations can create a dynamic integration where data from legacy systems can be accessed directly in Salesforce as if it were part of the native data structure.

Salesforce Connect uses external objects to link to external data sources, making it possible for users to interact with data across systems seamlessly. This method streamlines processes for organizations needing to maintain their legacy systems while still harnessing the full power of Salesforce for reporting and operational needs.

Integrating legacy data directly through this method allows for improved efficiency and reduces the time and resources needed to migrate large volumes of data. Rather than relying on imported data snapshots, users can always have up-to-date information that reflects real-time changes from legacy systems.
