Where should you run the SQL Query activities outlined in this module?

Running SQL Query activities in the top-level account of your Marketing Cloud Engagement tenant is advisable because it maintains consistent data governance and facilitates access to centralized data resources. This approach allows for streamlined management and ensures that the query operates within the broader context of your marketing strategy.

Top-level accounts generally have access to all data within the organization, making it easier to define and execute queries that involve multiple business units, segments, or datasets. This is crucial when your SQL queries need to pull data from various sources or when you aim to create cross-channel insights.

While other options like the largest business unit or the unit that sends the most emails might seem viable due to their specific functions, they can lead to limitations in scope and data accessibility. Running queries in a more restricted environment may not yield comprehensive insights or could complicate data management if the necessary data resides outside of that business unit. Hence, the top-level account is strategically the best location for executing SQL queries.
