## Directus-Specific Research

### Collection Design Best Practices

#### Naming Conventions
```typescript
// Directus collection naming standards
const namingConventions = {
  primary_collections: 'singular nouns (task, project, user)',
  junction_collections: 'plural_plural (tasks_tags, projects_users)',
  lookup_collections: 'plural (task_statuses, project_types)',
  integration_collections: 'prefix_suffix (task_ai_contexts, task_external_refs)',
  
  field_naming: {
    snake_case: true,           // tasks_completed_count
    descriptive: true,          // estimated_hours vs hours
    consistent_prefixes: true,  // is_active, has_dependencies
  }
};
```

#### Optimal Field Type Selection
```typescript
// Field type decisions for task management
const fieldTypeOptimization = {
  // Primary keys: UUID for distributed systems
  id: 'uuid',                  // Better than auto-increment for sync
  
  // Text fields: Length-based optimization
  title: 'string',             // <255 chars, indexed, searchable
  description: 'text',         // Unlimited length, full-text search
  
  // Status management: Flexibility vs performance
  status: 'uuid',              // FK to lookup table (flexible, translatable)
  priority: 'string',          // Enum as string (simple, fast queries)
  
  // Timestamps: Automatic vs manual
  created_at: 'timestamp',     // Automatic, UTC, database managed
  due_date: 'date',           // User-set, local timezone consideration
  
  // Structured data: JSON for flexibility
  metadata: 'json',           // Non-relational data
  ai_context: 'json',         // Complex nested structures
  
  // Relations: Proper relationship types
  project: 'uuid',            // Many-to-one (many tasks to one project)
  tags: 'alias',             // Many-to-many via junction table
  time_entries: 'alias',     // One-to-many reverse relation
};
```

#### Performance Optimization Patterns
```sql
-- Index strategies for common task management queries
-- Compound indexes for frequent filter combinations
CREATE INDEX idx_tasks_project_status ON tasks(project, status);
CREATE INDEX idx_tasks_assigned_status ON tasks(assigned_to, status);
CREATE INDEX idx_tasks_due_date ON tasks(due_date) WHERE due_date IS NOT NULL;

-- Partial indexes for active data
CREATE INDEX idx_active_tasks ON tasks(project, status) 
  WHERE status NOT IN ('completed', 'cancelled', 'archived');

-- Full-text search optimization
CREATE INDEX idx_tasks_search ON tasks 
  USING gin(to_tsvector('english', title || ' ' || description));

-- Performance-optimized dependency queries
CREATE INDEX idx_task_deps_dependent ON task_dependencies(dependent_task);
CREATE INDEX idx_task_deps_dependency ON task_dependencies(dependency_task);
```
