Without regard for brand, I don't think EITHER a database or spreadsheet is an appropriate choice for data mining--other than as a place to store data used in another (dedicated data mining) app.
I cannot imagine why anyone would fiddle around writing hundreds of queries and macros for whatever database, "cloud" or otherwise, when they can feed the data to RapidMiner or WEKA or Anaconda3 with a couple of mouse clicks, and get back information that would take a horrendous amount of time and effort to duplicate. Access and Excel (and the open-source clones and alternatives) are nice to store stuff, or to do simplistic, one-dimensional data manipulation. Not much more.
Of course, you can always take a shortcut, learn enough basic programming to stuff the data into a text file, and go straight to the data mining with RapidMiner, WEKA, or Anaconda3, find out what works, and use it.
