Is It Worth Learning MongoDB in 2020?
so looking at MongoDB in 2019,
It’s simple but immensely powerful! It’s free (open source) and solves the problem of storing, indexing and load balancing (all in one)! It’s none other than the most popular database solution across the globe- MongoDB.
One of the best things about MongoDB is that there are no restrictions on schema design. You can just drop a couple of documents within a collection and it isn’t necessary to have any relations between those documents. The only restriction with this is supported data structures.
MongoDB is comparatively faster as well. It is also very flexible and is an excellent database for companies considering scaling. Capable of handling a huge collection of data, MongoDB is used by extremely large teams.
But due to the absence of joins and transactions (which we will discuss later), you need to frequently optimize your schema based on how the application will be accessing the data.
Before you can store anything in MySQL, you need to clearly define tables and columns, and every row in the table should have the same column.
And because of this, there isn’t much space for flexibility in the manner of storing data if you follow normalization.
Some of its high-end customers include MTV, Craigslist, IBM, Orange S.A., The Gap, Uber, Google Search, Urban Outfitters, and eBay.
so now realizing it’s worth in 2019, you can anytime go and learn MongoDB through the youtube
