What method should be used to combine the "OpportunityWithAccount" and "CaseWithAccount" datasets to create a lens showing total opportunities and cases?

Using a SAQL (Salesforce Analytics Query Language) query is the appropriate method to combine the "OpportunityWithAccount" and "CaseWithAccount" datasets for the purpose of creating a comprehensive lens that displays the total opportunities and cases. SAQL is specifically designed for querying and manipulating data within Salesforce CRM Analytics, allowing for advanced data processing and combining information from multiple datasets.

By utilizing SAQL, users can write a query that aggregates the necessary data fields from both the Opportunity and Case datasets, making it possible to calculate totals or perform more complex transformations. This method provides the flexibility needed to customize the output, making it ideal for analytics purposes where specific aggregations and data relationships are important.

Other methods, such as Salesforce Direct query, may not offer the same level of flexibility needed to manipulate and combine multiple datasets effectively. "Compare Table" is typically used for side-by-side comparisons of data rather than merging datasets, and setting up Connect Data Sources involves linking external data into Salesforce rather than combining existing datasets. Therefore, the choice to use a SAQL query is not only suitable but also the most effective way to achieve the desired outcome for the analysis.
