I have used an unknown RAD tool for several years connecting a datafile.
Replaced the local datafile with Postgresql on Debian and I am today familiar with basic SQL. Very stable and rather simple to learn, but still learning.
Now trying to learn Golang. Not as simple as I expected...
Using Golang for our website. Built by HTML, CSS and Javascript and Golang as engine. In order to learn Go, I have created a test site https://go4webdev.org
