I started to the MongoDB developer course given online by MongoDB University. I have worked a lot with Mongo at Vodafone but I was using only 10-20% of its key features. Now at Politecnico, the things are more complex so I need to pay more attention to the performance issues. In my research project, I use MongoDB to store Tweets and perform text analysis over the records.
I currently completed the Week-1 course. I hope I will learn more in the upcoming weeks.
