Pireal 2.0.2 - Educational tool for working with RA
Some time ago in this same forum was announced the first release of Pireal.
Pireal is a tool that allows to evaluate queries written in the language of relational algebra and visualize the result of a particular query. All this from an intuitive interface.
What's new in this version is that an interpreter has been written from scratch to recognize the RA language. In addition the interface has improved greatly thanks to Qt5 and QtQuick Controls 2.
On the website you can see a demo of what Pireal does.
Thanks and regards! :)
