Rick from Comprehend here:

Comprehend isn't a BI tool. If all of a company's data is well-structured in a single database, with a non-changing data structure and without missing or null data, then it's easy to use BI tools like Tableau, Spotfire, Excel, etc.

But this is not the case in the modern day enterprise. Instead, there are dozens of different data collection systems, with different and changing data structures. This is what Comprehend's core technology was built to handle, in real-time.

In order to get similar functionality, companies are typically relying on teams of programmers to manually write and run scripts over and over again. Or, they're trying to put in place data warehouses, which rarely contain everything required and are often out of date.
