What relational dB to choose to study?

Only worked with mongoDb, I wanted to learn something new. Decided to take the relational database. How to start learning? What are the most popular and frequently needed when working with node? And how best to teach using ORM or pure?

Maria/ aka MySQL?

PS: has done the improvement... a Couple of arguments:
* Free for any use
* Fast enough with a smooth growth curve delays of the volume (the predictability of the load)
* The syntax is almost not "blurred" specific teams / designs, almost pure SQL
* opensores ( sobsno where the legs grow from Masha :) )
* A VERY common / is almost any hoster escalope.

PPS: Remember a minus - will not be able to hang on the wall of a beautiful(and expensive) certificate from MS/Oracle.
Thanks for the reply. As the eyes she immediately looked. - Cynthia.Donnelly commented on June 14th 19 at 19:01
I would recommend you to Google for the query "Disadvantages of MySQL" and "PostgreSQL vs MySQL". - samir39 commented on June 14th 19 at 19:04
