Learning MongoDB - Starting the 10gen Course

· Database Zone

My status on FB today was “Back to School”. After several years or running with the philosophy of “I don’t like sitting in classrooms” to learn technology, today I finally went back to an online classroom and it was to learn development with MongoDB.

The objective I started off was pretty simple – “I have worked with RDBMS several times in my life and now I want to know what does a “Document Store” like MongoDB brings to the table”. I hear everyone that we should move over to a NoSQL but I am not convinced in my head what problems it will really solve for me – scale, no-schema or something else. More importantly, I want to form a POV as to what I should be using a RBMS vs. a “Document Store” like a MongoDB.

I had registered for this “free” online course here (via a cross post on VOX that I cant seem to find). The week 1 course has about a dozen or so online lectures and they range from introducing Mongo, differences from relational, installations and some commands.  I love that it forces me to work on a schedule.

My first experience today after spending 1 hour on the course:

  1. Pretty easy to install and get going // I use a Mac and hence I had to use some manual steps, but I had the mongo db and shell up and running in about 10 minutes (download time included)
  2. Working with Shell is pretty simple // similar to working on a SQL shell for MySQL. No need to create any schema – just fire away and if you know JSON (which i did) i am entering records in under a minute
  3. Fetching records was even simpler – another couple of commands and I was rolling
