Dining Tracker — Redis In-Memory Key-Value Database

By: Ashsmith Khayrul

Students and community members often struggle to quickly access accurate nutrition information for dining hall menus. This project extends the Dining Tracker by introducing Redis as an in-memory key-value store to support fast access to frequently read or real-time data such as active user sessions, cached menu snapshots, view counts, and daily calorie totals.
