Technical Information

This page provides technical details about how the TCCD exam system is implemented, the technologies used, and how data is imported and processed.

Project Setup & Architecture

  • The exam system is built as a TYPO3 extension called typo3_exam_quiz
  • Uses Extbase framework for MVC architecture
  • Domain models: Exam, Question, Answer with repository pattern
  • Three main plugins: Quiz (exam taking), Explanation (question review), ExtensionInfo (this page)
  • FlexForms for backend configuration of each plugin

Technologies Used

  • Backend: PHP 8.1+, TYPO3 v12, Extbase/Fluid
  • Database: MySQL/MariaDB with Doctrine DBAL
  • Frontend: Fluid templating engine, vanilla JavaScript, CSS3
  • Data Format: EPUB books converted to XHTML, parsed and imported
  • Version Control: Git with GitLab
  • Deployment: Docker for development, traditional hosting for production

Data Import Process

  • Step 1: Official TCCD book comes as EPUB file
  • Step 2: EPUB renamed to .zip and extracted to get XHTML files
  • Step 3: Custom Symfony Console command parses XHTML structure
  • Step 4: Questions, answers, and metadata extracted from specific XHTML patterns
  • Step 5: Data validated and imported into database tables
  • Step 6: Images copied to fileadmin and paths updated
  • Command: dtypo3 examquiz:import:epub [path] --exam=tccd --pid=64 --all

Data Processing & Storage

  • Questions stored with chapter/section numbering (e.g., 1.2.3)
  • Multiple-choice answers with correct answer indicators
  • Explanations stored as rich text with HTML formatting
  • Images referenced with relative paths to fileadmin
  • Exam sessions stored in frontend user session
  • Results calculated in real-time during exam submission

Frontend Features

  • Responsive design for mobile, tablet, and desktop
  • Tab-based navigation with smooth transitions
  • Chapter selection for targeted practice
  • Random question ordering option
  • Question limit configuration
  • Immediate feedback with explanations
  • Statistics visualization with charts

Security & Performance
