At the end of a book, it makes sense to look back at what was discussed in the chapters to understand where to go next.
The book is intended to be an introduction to PostgreSQL for beginners, those who didn't have any experience with this RDBMS before, or who knew nothing about relational databases. The topic is quite vast and complex and, for this reason, even an entry-level book could not be simple.
In this chapter, we will summarize the topics we've covered in this book, and try to provide some tips and point the reader in the right direction for further learning.
First of all, if you are going to continue working with PostgreSQL, it makes sense have a link to its official documentation at https://www.postgresql.org/docs/current/static/index.html. The documentation is also available in French, Japanese, and Russian at https://www.postgresql.org...
