Low-Level Design Case Study: BookMyShow/Fandango
BookMyShow is an online ticketing service for cinemas, theaters, and sports. BookMyShow app helps users book movie tickets, concert tickets, sports tickets, and get access to events calendar, showtimes, movie reviews, and promotional offers, etc.
In this design round, We started from the requirement gathering and end up with designing the class diagram for the same, Also explored how can we write a sudo code from that. Below is the outline of the session/
1. Understanding of Problem Statement
2. Requirement Gathering.
3. Identifying the Actors and Creating a Usecase diagram
4. Understand complex execution flows with an Activity diagram
5. List down entities and the relationship between them to form a class diagram
6. Go through the class diagram
The Session will give you a brief insight into how to approach a Low-Level design for a given problem statement.
Please find the Sudo code repo and class diagram link.

@vishnusingh4118 3 жыл бұрын

Very informative! It would be great if you could do a hands-on Java code walk down to follow this up, telling how these things are implemented in an industry standard way. Since most of the target audience is relatively new to these things, learning industry-level best practices would be very useful. Thanks again for the fantastic video. Keep it up! :)

I have seen many videos on LLD but your's is best which is having class diagram in explanation. I am looking for more videos on LLD from your end so that we can get our concepts more clear. Sir please please please make more videos and add to the playlist.

Hi @TheCodeMate, Thank you for the insightful video on system design. However, I wanted to point out that BookMyShow primarily functions as an aggregator. Therefore, the actual seat availability and booking processes are likely managed by third parties or partners, such as Inox, who handle the ticket reservations. Could you consider creating a video explaining how such aggregators communicate with multiplexes or chains of multiplexes, how they display showtimes and seat availability in real-time, and how they facilitate real-time ticket bookings?

One quick question @thecodemate - database diagram is based on relational. how to choose directly relational instead of NoSQL?

@thecodemate7048 3 жыл бұрын

Hi Parth, Its a class diagram and not the database diagram. Adding to that selection of Database is highlevel design topic.

Bro can u create Notification alert for Movie ticket booking in Bookmyshow For particular movie date and theatre Sounds good right

@shatendrasingh6273 2 жыл бұрын

In the use case diagram, the external system(actor) is a web service that is being called to push the notifications out to the users. Is it so?

@thecodemate7048 Жыл бұрын

It may be service or it may be some job processing which takes chunk of data and process and send the notifications.

This is too much design for any interview

@thecodemate7048 3 жыл бұрын

For interview you are more focused on the class diagram and writing a sudo code. You might not need to explain whole design but its good to have this to come up with right entities.
