Some Mongo FunPosted: November 23, 2013
I’ve been doing “MongoDB for Node.js Developers” course from mongodb university and I’ve really enjoyed it. 5 weeks are over and hopefully the last week is not too bad. There are also courses for Java and Python developers that I plan to enroll for in future. I’m already very comfortable with the mongo shell and the other two courses shouldn’t be too bad, especially as I’ve been using Java on and off for a long time and Python is a fairly simple language.
Covered so far :
Some of the more interesting things I see compared to relational databases:
– Need to think of document as well as code in javascrip objects.
-Aggregation is an interesting concept in mongodb – it’s like pipe in unix – you can sequence steps e.g. restrict based on certain criteria , then group on something else followed by sorting.
I didn’t use any IDE for this course – mostly vi and later on Sublime text editor. I see that Robomango is an IDE that can be used but I didn’t use it yet.
I’ve put week5 examples at the below link :
