IEEEMDB - Personal Movie Diary & Social Platform

Project Description

IEEEMDB is a console-based application that allows users to:

• Add and manage users.
• Add and manage movies.
• Track watched movies per user.
• Write and view reviews and ratings.
• Suggest movies based on watched history. This is a simplified version of a personal movie diary and social network.

Functional Requirements

1. Add a new user.
2. Add a new movie.
3. Show list of users.
4. Show list of movies.
5. Add a watched movie to a user.
6. Show user's watched movies.
7. Add a review for a movie by a user.
8. Show all reviews.
9. Suggest movies based on watched history.

Non-Functional Requirements

1. Fast response time for adding and displaying data.
2. User-friendly console interface.
3. Scalable design to allow adding more features in the future.
4. Response time less than 200 ms
5. Service availability 99.9%
6. Secure communications via HTTPS
7. Error logging
8. Prioritize availability over consistency (CAP theorem)

Data Model

• User: username, email, watchedMovies (relation with Movie)
• Movie: title, genre
• Review: user → movie, text, rating

Relationships:

• A User can watch multiple Movies.
• A User can write multiple Reviews for Movies.
• Each Review belongs to one User and one Movie.

High-Level Architecture

The system consists of three main components:

1. User Management: manages users and their watched movies.
2. Movie Management: manages movies data.
3. Review Management: handles reviews and ratings.
4. [Web/Mobile App] --HTTP--> [API Server] --SQL--> [Database]--Redis-->Cache-->storage

API

• POST /users (register user)
• GET /movies (search movies)
• POST /movies/{id}/reviews (add review)

Deep Dives

1. Scalability: Using vectors is fine for small data, but for large-scale users/movies, a database is needed.
2. Data Consistency: Deleting a movie requires cleaning pointers from User's watched list.
3. Performance: Movie suggestions currently use linear search, which can be improved with indexing or maps.

How to Run

1. Open the project in your IDE (Visual Studio, Code::Blocks, etc.).
2. Build the project.
3. Run the executable.
4. Use the menu to add users, movies, reviews, and view suggestions.
