The application manages various data types including user profiles, posts, comments, exercises, workouts, likes, and social connections. It employs a hybrid approach using:

1. Cloud Firestore: Primary remote NoSQL database for dynamic, structured data like user information, posts, comments, likes, follows, workouts, and hashtags. Used for real-time updates where needed.
2. Firebase Authentication: Handles user authentication (signup, sign-in, session management).
3. Firebase Storage: Stores user-uploaded media like profile pictures, post images, and workout cover images.
4. Room Database: Local persistence library for:
   • Caching large datasets fetched initially (Exercises, Body Parts, Equipment, Targets).
   • Managing offline data or user-specific saves (Saved Workouts, Saved Exercises - based on flags/tables).
   • Handling optimistic UI updates and synchronization for actions like Likes (CachedLike table).
5. External API (ExerciseDB): Used by ExerciseRepository to fetch the initial, comprehensive list of exercises during first app launch.
