The key question is "Why" that needs to be asked. A customer may think they want to sort, select, and aggregate the data, but fundamentally "get the data" is very rarely the real reason for doing something.

That data is used to make a decision, and it's important that developers seek to understand exactly what that decision needs. Your users will often walk their way into a bad solution to their real problem because they will use their (incomplete) understanding of what is available.
