M121 - work platform

I am a Data Analyst and I am working with MongoDB aggregation framework for over a year using the Compass GUI… I have no idea why or how to work with the assigned variables, I’m quite fine with writing the stages at compass and I really can’t understand what should I do to obtain the numerical answers you ask for.
Is there any way to do the labs using only the Compass GUI?

Thank you,


Sorry; I’m afraid I can’t help you there. Compass is fine for a lot of things, but it is also somewhat limited in handling others, and I normally use the shell or command line for work. If you cannot figure out how to use the shell, then it will I’m afraid be up to you to figure out how to translate that into Compass. Good luck.
