Ruby on Rails and databases

In addition, Ruby on Rails is very database driven. To start, you do not need to know the features and scope of all modern databases - but experience with one relational database is needed. Better if it is PostgreSQL, but in fact, absolutely any relational database will do.

Now web developers are divided into specializations. Someone is well versed in the backend part: Ruby on Rails, databases, the Ruby language. Someone specializes in the frontend part: the visual presentation of the site using the JavaScript language, its frameworks, CSS cascading style sheets, HTML markup language. If your goal is to create a site alone, then to some extent you will have to master at least the basics of the profession of a frontend developer.
