The database can make use of a more expressive type system. Specifically to enforce invariants on data integrity at the schema level. But also understanding databases from a type theoretic point of view can lead to better, safer and more expressive type systems.

You do not want to keep writing database validation code in your application boundary. That is tiring. Instead let your database do that work. After all, it is where the data is stored. It is where the data is migrated. So shouldn't it also maintain the integrity and the constraints of the data?

PdfLatex is a tool that converts Latex sources into PDF. This is specifically very important for researchers, as they use it to publish their findings. It could be installed very easily using Linux terminal, though this seems an annoying task on Windows. Installation commands are given below.

• Install the TexLive base

sudo apt-get install texlive-latex-base

• Also install the recommended and extra fonts to avoid running into the error [1], when trying to use pdflatex on latex files with more fonts.
