Schéma de Base de Données - Kit'Asso Documentation

Vue d’ensemble

Kit’Asso utilise 13 tables PostgreSQL hébergées sur Nhost et exposées via Hasura GraphQL. La base de données est organisée en 4 domaines fonctionnels : le catalogue d’outils, les workflows guidés, les packs curés et le système de quiz avec scoring pondéré V2. Architecture :

Core Tables (5) : tools, categories, filters, tool_features, site_assets
Workflow Tables (2) : workflows, workflow_steps
Pack System (2) : tool_packs, pack_tools
Quiz System (5) : quizzes, quiz_questions, quiz_answers, quiz_recommendations, quiz_responses

Accès aux données :

GraphQL via Hasura (auto-généré depuis le schéma PostgreSQL)

Core Tables

1. tools

Table principale du catalogue d’outils numériques. Colonnes :

CREATE TABLE tools (
  id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
  name TEXT UNIQUE NOT NULL,
  description TEXT NOT NULL,
  pricing_tier TEXT CHECK (pricing_tier IN ('Gratuit', 'Freemium', 'Payant', 'Entreprise')),
  category_id UUID REFERENCES categories(id) ON DELETE SET NULL,
  logo_url TEXT,
  website_url TEXT,
  created_at TIMESTAMPTZ DEFAULT NOW()
);

Type TypeScript :

interface Tool {
  id: string;
  name: string;
  description: string;

Cascades :

Suppression d’un tool → supprime ses tool_features et pack_tools
Suppression d’un workflow → supprime ses workflow_steps
Suppression d’un quiz → supprime questions, answers, recommendations, responses
Suppression d’une category → SET NULL sur tools.category_id
