How PGSimCity Turns PostgreSQL Complexity Into a Virtual City 3D Simulation

Nikolay Samokhvalov has developed PGSimCity, an open-source educational tool that visualises PostgreSQL mechanics as a 3D spatial simulation in the browser. It assists backend developers and site reliability engineers in understanding SQL and the dynamics of kernel execution. The project is available on GitHub and aims to enhance understanding of database architecture through interactive elements. By Olimpiu Pop
