Architecture Base de données - Kit'Asso Documentation

Vue d’ensemble

Kit’Asso utilise PostgreSQL via Nhost (avec Hasura GraphQL) avec des tables organisées en 4 groupes fonctionnels :

Core

Tools, Categories, Filters

Workflows

Workflows, Workflow Steps

Packs

Tool Packs, Pack Tools

Quiz

Quizzes, Questions, Answers, Recommendations, Responses

Statistiques :

13 tables avec relations complètes
Row Level Security (RLS) sur toutes les tables
43 fichiers de migration trackés
2 buckets Storage (tool_logos, site_assets)

Schéma relationnel

Groupe 1 : Core (Outils)

Table `tools`

Catalogue principal des outils numériques.

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),
  logo_url TEXT,
  website_url TEXT,
  created_at TIMESTAMPTZ DEFAULT NOW()
);

Colonnes clés :

pricing_tier : Enum strict pour cohérence
category_id : Foreign key vers categories
logo_url : URL publique depuis Nhost Storage

Indexes :

CREATE INDEX idx_tools_category ON tools(category_id);
CREATE INDEX idx_tools_pricing ON tools(pricing_tier);

Table `categories`

Classification des outils par usage.

CREATE TABLE categories (
  id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
  name TEXT UNIQUE NOT NULL,
  created_at TIMESTAMPTZ DEFAULT NOW()
);

Exemples de données :

Communication
Gestion de projet
Site Web
Paiements & Dons
Automatisation

Table `filters`

Features et capacités des outils.

CREATE TABLE filters (
  id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
  filter_type TEXT NOT NULL,
  value TEXT NOT NULL,
  feature_type TEXT,
  created_at TIMESTAMPTZ DEFAULT NOW()
);

Types de filters :

filter_type = ‘capability’ → Fonctionnalités (Email Marketing, CRM)
filter_type = ‘integration’ → Intégrations (Zapier, Stripe)
filter_type = ‘platform’ → Plateformes (Web, Mobile, Desktop)

Table `tool_features` (Jointure)

Relation Many-to-Many entre tools et filters.

CREATE TABLE tool_features (
  id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
  tool_id UUID REFERENCES tools(id) ON DELETE CASCADE,
  filter_id UUID REFERENCES filters(id) ON DELETE CASCADE,
  created_at TIMESTAMPTZ DEFAULT NOW(),
  UNIQUE(tool_id, filter_id)
);

Requête typique :

-- Récupérer un outil avec ses features
SELECT 
  t.*,
  ARRAY_AGG(f.value) as features
FROM tools t
LEFT JOIN tool_features tf ON t.id = tf.tool_id
LEFT JOIN filters f ON tf.filter_id = f.id
WHERE t.id = $1
GROUP BY t.id;

Groupe 2 : Workflows

Table `workflows`

CREATE TABLE workflows (
  id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),

  category TEXT NOT NULL,
  icon TEXT NOT NULL,
  status TEXT CHECK (status IN ('active', 'draft')) DEFAULT 'draft',
  steps JSONB NOT NULL,
  display_order INTEGER DEFAULT 0,
  objective TEXT,
  completion_message TEXT,
  next_steps JSONB DEFAULT '[]',
  resources JSONB DEFAULT '[]',
  created_at TIMESTAMPTZ DEFAULT NOW(),

);

Colonnes importantes :

steps : JSONB avec structure [{ title, description, tool }]
status : Seuls les workflows ‘active’ sont visibles publiquement
display_order : Ordre d’affichage dans l’interface

Exemple de steps JSONB :

[
  {
    "title": "Choisir votre outil d'emailing",
    "description": "Comparez Mailchimp et Sendinblue",
    "tool": "Mailchimp",
    "duration": "10min"
  },
  {
    "title": "Créer votre première campagne",
    "description": "Configurez les paramètres de base",
    "tool": "Mailchimp",
    "duration": "15min"
  }
]

  story JSONB,
  visuals JSONB,
  videos JSONB,
  created_at TIMESTAMPTZ DEFAULT NOW(),
  updated_at TIMESTAMPTZ DEFAULT NOW()
);

Structure enrichie pour pédagogie :

detailed_instructions : Liste JSONB d’instructions
completion_checklist : Array de tâches à cocher
story : Contexte narratif (persona, situation, goal)
visuals : Screenshots, diagrammes
videos : Tutoriels vidéo

Exemple de story JSONB :

  "persona": "Marie, présidente d'association",
  "situation": "Besoin d'envoyer une newsletter mensuelle",
  "goal": "Créer et envoyer sa première campagne"
}

  UNIQUE(pack_id, tool_id)
);

Requête typique :

-- Récupérer un pack avec ses outils
SELECT 
  tp.*,
  COUNT(pt.tool_id) as tool_count,
  ARRAY_AGG(
    json_build_object(
      'id', t.id,
      'name', t.name,
      'logo_url', t.logo_url
    ) ORDER BY pt.display_order
  ) as tools
