Answer 1

Too long for a comment:

Based on your given code I created a MWE, that means I reduced your given code to the minimal size reproducing the error.

In your case--as already mentioned in comments--you are missing the run of biber.

Lets start with the MWE:

\RequirePackage{filecontents}
\begin{filecontents}{\jobname.bib}
@book{book_key,
    address = {São Paulo},
    publisher = {Clube de Autores},
    author = {carvalho, Leandro},
    title = {SW Tutorial},
    year = {2017},
    volume = {1},
    series = {1},
    edition = {1},
    pages = {123--200},
    month = {January}
}
@article{article_key,
    address = {City},
    publisher = {Publisher},
    author = {Smith, James},
    title = {Article title},
    year = {2013},
    volume = {14},
    number = {6},
    pages = {1--8},
    month = {March}
}
\end{filecontents}

Please copy it to your computer and save it for example under the name mwe.tex.

Now open your terminal/console and start compiling:

pdflatex mwe.tex

That compile run gives you a new file mwe.aux needed for biber. Now use command

biber mwe

to get two files mwe.blg (log file, check it for errors and warnings) and mwe.bbl.

Now compile twice

pdflatex mwe.tex
pdflatex mwe.tex

to finish the TeX document. Now you should see your bibliography. If not, check both log files mwe.log and mwe.blg for errors or warnings ...

Depending on your used editor you can start the run of biber after proper configuration of the editor. Please see, if your editor is described in question Biblatex with Biber: Configuring my editor to avoid undefined citations.

EDIT by OP:

Process successfully using TeXworks.

Now fully functional using TeXstudio.
