*2.1. Web Server and Code*

The GDS is based on the web server software Apache (v2.4.41) on Linux operating system. PHP (v7.4) and MySQL (v8.0) were used for back-end code and HTML5, CSS3, and JavaScript for front-end codes. All codes have been submitted to Github (https: //github.com/, accessed on 25 December 2021) and can be accessed for free by entering "Han-Oscar/GDS-code". Data were deposited into the mysql database in batches and displayed on the website upon searching using Navicat (version 15) software.
