Designing normalized data architectures, high-performance indexing strategies, ACID transactional guarantees, and distributed caches.
Inspecting normalized table schemas, primary keys (`PK`), foreign keys (`FK`), compound indexes (`IDX`), and data relations.
| Attribute | Type | Constraint | Purpose & Index Strategy |
|---|---|---|---|
| id | UUID | PK | Primary identifier |
| user_id | UUID | FK | Owner foreign key |
| slug | VARCHAR(120) | IDX | URL routing identifier |
| title | VARCHAR(200) | - | Project headline |
| tech_stack | JSONB | JSONB | Indexed tags & metadata |
| is_featured | BOOLEAN | IDX | Filtered showcase flag |
| created_at | TIMESTAMP | - | Creation timestamp |
projects.user_id -> users.id
project_skills (junction)
SELECT p.id, p.title, p.slug, u.email, COUNT(s.id) AS skill_count FROM projects p INNER JOIN users u ON p.user_id = u.id LEFT JOIN project_skills ps ON ps.project_id = p.id LEFT JOIN skills s ON s.id = ps.skill_id WHERE p.is_featured = true AND p.category = 'fullstack' GROUP BY p.id, u.email ORDER BY p.created_at DESC LIMIT 6;
Purpose: Fetches featured portfolio projects with aggregated skills while avoiding full table locks.
Index Scan using idx_projects_featured_created
