How to get started learning databases in C++ on Ubuntu?

Question

MySQL

Hello everyone . I study programming (exclusively for myself).
Now stopped on a C ++. I work in Code Blocks IDE (if it matters). I am practically unfamiliar with databases.
What sources of literature or books can you recommend for studying this topic?
Requirements :

• compatible with Ubuntu 14.04
  
• opportunity to learn C++
  
• and that this knowledge is enough to learn databases in Java.
  

Source types:

• web
  
• books
  
• video courses
  
• language (English or Russian)
  

What efforts did I make :

• worked in Access (but I did not like it because of the buggy software environment)
  
• have a fragmented experience with MySQL (at the level of creating simple queries using PHP)
  
• a lot of google
  
• ---- someone advises MySQL (and I liked it because I was fluent in this technology)
  
• ---- others refer to PostgreSQL (very interested)
  
• habr and a toaster (I did not find any information on my parameters)
  

Before asking a question, I spent a lot of time on independent research of my question (I did not find complete and useful information).
PS: My question is most likely not correct due to poor preparation, I hope for your understanding.

Answer 1

As far as I know, it can be assumed that MS SQL will only run on the MS platform (and then, maybe you can run it under Linux through wine).
Almost all other databases work under Linux, including Ubuntu.
For C++ there are libraries for any database.
You don't need to learn C++ from a database, but just learn SQL and then just use it from your programming language.
Also, keep in mind that the database can be hosted on any remote server.
