**Data Layer (Database – MongoDB via Mongoose)**
|
|
|
|
Persistent data storage is handled by MongoDB, with Mongoose used for schema validation and object modeling.
|
|
|
|
The database structure supports the following collections:
|
|
|
|
- Users: Stores account credentials, BMI data, and user preferences
|
|
|
|
- Groups: Records group metadata and member associations
|
|
|
|
- Items: Contains inventory items with attributes like expiry, price, and calorie value
|
|
|
|
- Logs: Tracks food consumption history and financial records
|
|
|
|
|
|
|
|
This flexible schema supports efficient querying and easy schema evolution, enabling real time group synchronization and historical data analytics.
