SQL Trainer

SQL training game written in Javascript

Configuration

  • Tasks and books can be configured via .task and .book files.
  • For translating into more languages, add a /i18n/<lang>.js, /books/<lang>/Book-<>.book files and /tasks/<lang>/Task-<>.task files, as well as an option to language-selector element in index.html
  • Progression can be configured in /tasks/progression.js
  • Editors for books, tasks and progression can be found from /editors.html

Extra information:

Deployment

  • Place all files to a webserver so that index.html is loaded from some address.
  • Prevent access to editors.html if you don't want students who find it to read tasks and books ahead of time.
