Mini Movie Database

Overview

The ConsoleApp.MiniMovieDatabase is a console-based application designed to manage a simple movie database. It allows users to perform CRUD (Create, Read, Update, Delete) operations on movie records.

Key Components

1. Movie Class:

   • Represents a movie entity with properties such as Title, Director, ReleaseYear, and Genre.
   • Example:

     public class Movie
     {
         public string Title { get; set; }
         public string Director { get; set; }
         public int ReleaseYear { get; set; }
         public string Genre { get; set; }
     }

2. MovieRepository Class:

   • Manages a collection of movies.
   • Provides methods to add, view, update, and delete movies.
   • Example methods:

     public void AddMovie(Movie movie) { ... }
     public Movie GetMovie(string title) { ... }
     public void UpdateMovie(string title, Movie updatedMovie) { ... }
     public void DeleteMovie(string title) { ... }

3. MovieService Class:

   • Acts as an intermediary between the console application and the MovieRepository.
   • Contains business logic to ensure data integrity and validation before performing repository operations.
   • Example methods:

     public void AddMovie(Movie movie) { ... }
     public void DisplayAllMovies() { ... }
     public void UpdateMovie(string title, Movie updatedMovie) { ... }
     public void RemoveMovie(string title) { ... }

4. Console Interface:

   • Provides a user interface for interacting with the movie database.
   • Handles user input and displays information to the user.
   • Example interaction:

     Console.WriteLine("Enter movie title:");
     string title = Console.ReadLine();

Example Usage

1. Adding a Movie:

   var movie = new Movie
   {
       Title = "Inception",
       Director = "Christopher Nolan",
       ReleaseYear = 2010,
       Genre = "Sci-Fi"
   };
   movieService.AddMovie(movie);

2. Viewing Movies:

   movieService.DisplayAllMovies();

3. Updating a Movie:

   var updatedMovie = new Movie
   {
       Title = "Inception",
       Director = "Christopher Nolan",
       ReleaseYear = 2010,
       Genre = "Science Fiction"
   };
   movieService.UpdateMovie("Inception", updatedMovie);

4. Deleting a Movie:

   movieService.RemoveMovie("Inception");

Conclusion

The ConsoleApp.MiniMovieDatabase provides a straightforward way to manage movie records through a console interface, demonstrating basic principles of object-oriented programming and CRUD operations.
