I successfully completed this course with a 97.7% mark. This course was once again broad and touched upon some big data technologies through a series of lectures, assignments and hands-on exercises. The focus was mainly on querying JSON data using MongoDB, analysing data using Pandas, and programming in Spark (Spark SQL, Spark Streaming, Spark MLLIB and Spark GraphX). All these were things I was curious about and it was great that they introduced these in the course. There were also an exercise on analysing tweets using both MongoDB and Spark. They had one section on something called Splunk which I thought was a waste of time but I guess they have to keep their sponsors happy.
This specialisation so far (I’m halfway through) has been fairly introductory and lacking depth. It’s been good to the extent that I feel like I’m aware of all these different technologies and would be able to know where to start if I was to use them for some specific application. As I expected, this course was more hands-on which was great!
