Stores user-related data and preferences |
| Flavors | flavor_id (UUID), name, description, ingredients (JSONB), nutritional_info (JSONB) |
Maintains detailed flavor info for linking feedback |
| Feedback | feedback_id (UUID), user_id, flavor_id, rating (1–5), comment, sentiment_score |
Captures user feedback linked to flavor |
| Polls | poll_id (UUID), question, options (JSONB), created_date, expiration_date |
Holds quick poll questions for targeted feedback |
| Poll Responses | response_id (UUID), user_id, poll_id, selected_option, timestamp |
Stores user poll answers |
5. Advanced Data Collection & User Engagement Strategies
- Use intuitive star rating systems embedded in apps and websites.
- Encourage textual feedback, supported by NLP sentiment analysis to extract trends.
- Implement in-app polls through quick, focused questions using integrated platforms like Zigpoll.
- Add gamification elements—badges, leaderboards—to boost user participation.
- Deploy push notifications and email surveys tailored by purchase and preference data.
6. Real-Time Analytics and Insight Generation
Real-time aggregation of average flavor ratings, response volumes, and sentiment distributions.
User segmentation by location, age, or purchase history to identify niche trends.
Visual dashboards presenting metrics such as:
- Flavor popularity heatmaps
- Sentiment trends over time
- Demographic-specific feedback breakdowns
7. Personalization with Machine Learning
- Build flavor recommendation engines using collaborative and content-based filtering with frameworks like Scikit-learn or TensorFlow.
- Drive dynamic marketing: personalized emails, push notifications, and flavor bundling offers.
- Perform A/B testing for new flavors and marketing prompts, feeding results back into the system.
8. Key Performance Indicators (KPIs)
- Feedback Volume: Number of ratings and reviews over time.
- Average Flavor Ratings: Track average scores and their variance.
- Sentiment Analysis Trends: Positive, neutral, and negative sentiment shifts.
- User Retention & Repeat Purchase Rates: Correlate with feedback engagement.
- Poll Response Rate: Measure participation in quick polls.
- Personalization CTR: Click-through rates on recommended flavors.
9. Ensuring Data Security and Regulatory Compliance
- Apply role-based access control restricting sensitive data.
- Encrypt data at rest and in transit (e.g., TLS, AES).
- Hash and salt user passwords with secure algorithms (bcrypt).
- Pseudonymize user data and allow data export/deletion on request.
- Perform regular security audits and vulnerability assessments.
10. Streamline Feedback Collection with Zigpoll Integration
Integrating Zigpoll enhances backend efficiency by providing:
