About This Architecture

Gamified educational system ER diagram modeling users, students, teachers, classes, activities, performance tracking, and avatar progression mechanics. The schema separates USUARIO (base user) into ALUNO (student) and PROFESSOR (teacher) via inheritance, with TURMA (class) linking professors to students and activities. Student engagement is captured through DESEMPENHO (performance scores and audio responses), FASE (level progression with star ratings), and LOJA/AVATAR (in-game currency and collectible rewards). This normalized structure supports real-time progress tracking, phoneme-based activity sequencing, and gamification incentives critical for retention in educational platforms. Fork and customize this diagram on Diagrams.so to adapt the schema for your learning management system, add additional reward mechanics, or integrate assessment workflows. The N:N relationship via LOJA_AVATAR enables flexible avatar pricing and inventory management without coupling student purchases to specific avatar definitions.

What is the database schema structure for a gamified educational platform with student progression and avatar rewards?

This ER diagram defines a normalized schema where USUARIO splits into ALUNO and PROFESSOR via inheritance, TURMA links teachers to students and activities, DESEMPENHO tracks student performance on phoneme-based activities, FASE manages level progression with star ratings, and LOJA/AVATAR handles in-game currency and collectible rewards through an N:N junction table.
