This folder is a web done in php language. To access it from a browser, a web server program such as apache, xampp, nginx, etc is needed. Once you have a running web server software running in your computer, put the whole package in the correct place inside the web server (for example, the 'htdocs' folder), and then go to: "http://localhost/waterbase-uwwtd/src/2-web/" and the web platform that reads the sqlite database will start loading.
