+# Database Schema Documentation
+
+## Overview
+
+This document provides a comprehensive overview of the Mila Membership Management System database schema.
+
+## Quick Links
+
+- **DBML File:** [`database_schema.dbml`](./database_schema.dbml)
+- **Visualize Online:** 
+  - [dbdiagram.io](https://dbdiagram.io) - Upload the DBML file
+  - [dbdocs.io](https://dbdocs.io) - Generate interactive documentation
+
+## Schema Statistics
+
+| Metric | Count |
+|--------|-------|
+| **Tables** | 5 |
+| **Domains** | 2 (Accounts, Membership) |
+| **Relationships** | 3 |
+| **Indexes** | 15+ |
+| **Triggers** | 1 (Full-text search) |
+
+## Tables Overview
+
+### Accounts Domain
+
+#### `users`
+- **Purpose:** User authentication and session management
+- **Rows (Estimated):** Low to Medium (typically 10-50% of members)
+- **Key Features:** 
+  - Dual authentication (Password + OIDC)
+  - Optional 1:1 link to members
+  - Email as source of truth when linked
+
+#### `tokens`
+- **Purpose:** JWT token storage for AshAuthentication
+- **Rows (Estimated):** Medium to High (multiple tokens per user)
+- **Key Features:**
+  - Token lifecycle management
+  - Revocation support
+  - Multiple token purposes
+
+### Membership Domain
+
+#### `members`
+- **Purpose:** Club member master data
+- **Rows (Estimated):** High (core entity)
+- **Key Features:**
+  - Complete member profile
+  - Full-text search via tsvector
+  - Bidirectional email sync with users
+  - Flexible address and contact data
+
+#### `properties`
+- **Purpose:** Dynamic custom member attributes
+- **Rows (Estimated):** Variable (N per member)
+- **Key Features:**
+  - Union type value storage (JSONB)
+  - Multiple data types supported
+  - One property per type per member
+
+#### `property_types`
+- **Purpose:** Schema definitions for custom properties
+- **Rows (Estimated):** Low (admin-defined)
+- **Key Features:**
+  - Type definitions
+  - Immutable and required flags
+  - Centralized property management
+
+## Key Relationships
+
+```
+User (0..1) ←→ (0..1) Member
+       ↓
+    Tokens (N)
+
+Member (1) → (N) Properties
+                    ↓
+              PropertyType (1)
+```
+
+### Relationship Details
+
+1. **User ↔ Member (Optional 1:1, both sides optional)**
+   - A User can have 0 or 1 Member (`user.member_id` can be NULL)
+   - A Member can have 0 or 1 User (optional `has_one` relationship)
+   - Both entities can exist independently
+   - Email synchronization when linked (User.email is source of truth)
+   - `ON DELETE SET NULL` on user side (User preserved when Member deleted)
+
+2. **Member → Properties (1:N)**
+   - One member, many properties
+   - `ON DELETE CASCADE` - properties deleted with member
+   - Composite unique constraint (member_id, property_type_id)
+
+3. **Property → PropertyType (N:1)**
+   - Properties reference type definition
+   - `ON DELETE RESTRICT` - cannot delete type if in use
+   - Type defines data structure
+
+## Important Business Rules
+
+### Email Synchronization
+- **User.email** is the source of truth when linked
+- On linking: Member.email ← User.email (overwrite)
+- After linking: Changes sync bidirectionally
+- Validation prevents email conflicts
+
+### Authentication Strategies
+- **Password:** Email + hashed_password
+- **OIDC:** Email + oidc_id (Rauthy provider)
+- At least one method required per user
+
+### Member Constraints
+- First name and last name required (min 1 char)
+- Email unique, validated format (5-254 chars)
+- Birth date cannot be in future
+- Join date cannot be in future
+- Exit date must be after join date
+- Phone: `+?[0-9\- ]{6,20}`
+- Postal code: 5 digits
+
+### Property System
+- Maximum one property per type per member
+- Value stored as union type in JSONB
+- Supported types: string, integer, boolean, date, email
+- Types can be marked as immutable or required
+
+## Indexes
+
+### Performance Indexes
+
+**members:**
+- `search_vector` (GIN) - Full-text search
+- `email` - Email lookups
+- `last_name` - Name sorting
+- `join_date` - Date filtering
+- `paid` (partial) - Payment status queries
+
+**properties:**
+- `member_id` - Member property lookups
+- `property_type_id` - Type-based queries
+- Composite `(member_id, property_type_id)` - Uniqueness
+
+**tokens:**
+- `subject` - User token lookups
+- `expires_at` - Token cleanup
+- `purpose` - Purpose-based queries
+
+**users:**
+- `email` (unique) - Login lookups
+- `oidc_id` (unique) - OIDC authentication
+- `member_id` (unique) - Member linkage
+
+## Full-Text Search
+
+### Implementation
+- **Trigger:** `members_search_vector_trigger()`
+- **Function:** Automatically updates `search_vector` on INSERT/UPDATE
+- **Index Type:** GIN (Generalized Inverted Index)
+
+### Weighted Fields
+- **Weight A (highest):** first_name, last_name
+- **Weight B:** email, notes
+- **Weight C:** birth_date, phone_number, city, street, house_number, postal_code
+- **Weight D (lowest):** join_date, exit_date
+
+### Usage Example
+```sql
+SELECT * FROM members 
+WHERE search_vector @@ to_tsquery('simple', 'john & doe');
+```
+
+## Database Extensions
+
+### Required PostgreSQL Extensions
+
+1. **uuid-ossp**
+   - Purpose: UUID generation functions
+   - Used for: `gen_random_uuid()`, `uuid_generate_v7()`
+
+2. **citext**
+   - Purpose: Case-insensitive text type
+   - Used for: `users.email` (case-insensitive email matching)
+
+### Installation
+```sql
+CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
+CREATE EXTENSION IF NOT EXISTS "citext";
+```
+
+## Migration Strategy
+
+### Ash Migrations
+This project uses Ash Framework's migration system:
+
+```bash
+# Generate new migration
+mix ash.codegen --name add_new_feature
+
+# Apply migrations
+mix ash.setup
+
+# Rollback migrations
+mix ash_postgres.rollback -n 1
+```
+
+### Migration Files Location
+```
+priv/repo/migrations/
+├── 20250421101957_initialize_extensions_1.exs
+├── 20250528163901_initial_migration.exs
+├── 20250617090641_member_fields.exs

+└── 20251016130855_add_constraints_for_user_member_and_property.exs
+```
+
+## Data Integrity
+
+### Foreign Key Behaviors
+
+| Relationship | On Delete | Rationale |
+|--------------|-----------|-----------|
+| `users.member_id → members.id` | SET NULL | Preserve user account when member deleted |
+| `properties.member_id → members.id` | CASCADE | Delete properties with member |
+| `properties.property_type_id → property_types.id` | RESTRICT | Prevent deletion of types in use |
+
+### Validation Layers
+
+1. **Database Level:**
+   - CHECK constraints
+   - NOT NULL constraints
+   - UNIQUE indexes
+   - Foreign key constraints
+
+2. **Application Level (Ash):**
+   - Custom validators
+   - Email format validation (EctoCommons.EmailValidator)
+   - Business rule validation
+   - Cross-entity validation
+
+3. **UI Level:**
+   - Client-side form validation
+   - Real-time feedback
+   - Error messages
+
+## Performance Considerations
+
+### Query Patterns
+
+**High Frequency:**
+- Member search (uses GIN index on search_vector)
+- Member list with filters (uses indexes on join_date, paid)
+- User authentication (uses unique index on email/oidc_id)
+- Property lookups by member (uses index on member_id)
+
+**Medium Frequency:**
+- Member CRUD operations
+- Property updates
+- Token validation
+
+**Low Frequency:**
+- PropertyType management
+- User-Member linking
+- Bulk operations
+
+### Optimization Tips
+
+1. **Use indexes:** All critical query paths have indexes
+2. **Preload relationships:** Use Ash's `load` to avoid N+1
+3. **Pagination:** Use keyset pagination (configured by default)
+4. **Partial indexes:** `members.paid` index only non-NULL values
+5. **Search optimization:** Full-text search via tsvector, not LIKE
+

+
+### Using dbdiagram.io
+
+1. Visit [https://dbdiagram.io](https://dbdiagram.io)
+2. Click "Import" → "From file"
+3. Upload `database_schema.dbml`
+4. View interactive diagram with relationships
+
+### Using dbdocs.io
+
+1. Install dbdocs CLI: `npm install -g dbdocs`
+2. Generate docs: `dbdocs build database_schema.dbml`
+3. View generated documentation
+
+### VS Code Extension
+
+Install "DBML Language" extension to view/edit DBML files with:
+- Syntax highlighting
+- Inline documentation
+- Error checking
+
+## Security Considerations
+
+### Sensitive Data
+
+**Encrypted:**
+- `users.hashed_password` (bcrypt)
+
+**Should Not Log:**
+- hashed_password
+- tokens (jti, purpose, extra_data)
+
+**Personal Data (GDPR):**
+- All member fields (name, email, birth_date, address)
+- User email
+- Token subject
+
+### Access Control
+
+- Implement through Ash policies
+- Row-level security considerations for future
+- Audit logging for sensitive operations
+
+## Backup Recommendations
+
+### Critical Tables (Priority 1)
+- `members` - Core business data
+- `users` - Authentication data
+- `property_types` - Schema definitions
+
+### Important Tables (Priority 2)
+- `properties` - Member custom data
+- `tokens` - Can be regenerated but good to backup
+
+### Backup Strategy
+```bash
+# Full database backup
+pg_dump -Fc mv_prod > backup_$(date +%Y%m%d).dump
+
+# Restore
+pg_restore -d mv_prod backup_20251110.dump
+```
+
+## Testing
+
+### Test Database
+- Separate test database: `mv_test`
+- Sandbox mode via Ecto.Adapters.SQL.Sandbox
+- Reset between tests
+
+### Seed Data
+```bash
+# Load seed data
+mix run priv/repo/seeds.exs
+```
+
+## Future Considerations
+
+### Potential Additions
+
+1. **Audit Log Table**
+   - Track changes to members
+   - Compliance and history tracking
+
+2. **Payment Tracking**
+   - Payment history table
+   - Transaction records
+   - Fee calculation
+
+3. **Document Storage**
+   - Member documents/attachments
+   - File metadata table
+
+4. **Email Queue**
+   - Outbound email tracking
+   - Delivery status
+
+5. **Roles & Permissions**
+   - User roles (admin, treasurer, member)
+   - Permission management
