Day 35

MongoDB

Finally, we get to work with NoSQL! For those who don't know, NoSQL is known as Not Only SQL. In SQL, there are strict rules in how columns are changed. For example, let's say person 1 has height, weight attribute. And person 2 has height, eye color and hair color attributes. In SQL, you wouldn't be able to put these two people in the same table and you would actually have to construct multiple tables just to hold these two people! In MongoDB, all that doesn't matter and you can plug these people into the DB. So the first assignment is to work with the syntax of how to insert and manipulate data in Mongo.

The next thing we learned is Mongoose, which is just a layer between our server file and our MongoDB. Mongoose provides a bit more structure for MongoDB. Mongoose also lets us be able to insert and pull data from and to the database. Although similar, Mongoose has its own documentation and has its pros: built-in methods such has update() that allows for easier to understand and less verbose writing it out in MongoDB. Our assignments are all pretty straightforward and we've done them all before, but never in JS with its own JS DB. We're expected to finish the rest of MongoDB over the weekend and start on AngularJS next week!
