Question

Using a distributed object approach, propose an architecture for a national theatre booking system where users can check seat availability and book seats at a group of theatres. The system should support ticket returns so that people may return their tickets for last-minute resale to other customers.

Short answer

Create a distributed system with theatre objects, a service layer for booking and returns, and a synchronized database for seat availability.

Step-by-step solution

Define Requirements

Identify the key requirements for the theatre booking system. The system needs to handle multiple theatres and should allow users to check seat availability, book seats, and return tickets. It should also enable last-minute resales.

Establish Core Components

Outline the core components required in the architecture. These include a User Interface for customers, a Booking Service, a Ticket Management Service, a Theatres Database, and a Notification Service for updates and confirmations.

Implement Distributed Object Architecture

Use a distributed object-oriented approach. Each theatre operates as a standalone, distributed object, which can handle requests independently. This modularity ensures scalability and flexibility for adding more theatres.

Design the User Interface

Create a user interface that allows customers to browse theatres, view seat availability, book seats, and process ticket returns. This will be connected to the backend services to send and receive data.

Develop Service Layer

Implement a central Service Layer that includes Booking Service, Ticket Management Service, and Notification Service. The Booking Service will interface with Theatre Objects; Ticket Management will handle ticket sales and returns.

Synchronize the Theatres Database

Maintain a central database that synchronizes data from all theatre objects, ensuring consistency of seat availability and bookings across the system. This may be implemented using a distributed database solution.

Implement Notification Mechanism

Develop a Notification Service that sends email or SMS confirmations to users upon booking or returning tickets. This ensures users are informed of their transactions.

Support Ticket Resale

Add functionality to the Ticket Management Service for reselling returned tickets to other users. When a ticket is returned, it goes back into the system for resale, updating availability in real-time.

Key concepts

Theatre Booking System

A theatre booking system is at the core of ensuring a seamless experience for those eager to enjoy live performances. It manages various interconnected parts that work together to allow users to browse available shows, check seat availability, book tickets, and even return them if necessary. In this national theatre booking setup, the system needs to handle data from multiple theatres, enabling efficient management of seat inventory.

• Users should be able to access an interface that lets them see which seats are available.
• The system must support booking and returning tickets to maximize theatre occupancy.
• Efficient ticket resale functionality allows returned tickets to be sold to other customers, increasing sales opportunities.

This system must be robust enough to handle peak times and numerous transactions concurrently without malfunctioning.

Ticket Management

Ticket management is an essential function in the theatre booking system, responsible for the lifecycle of tickets from purchase to potential return and resale. An effective ticket management system needs to be user-friendly while meticulously tracking each ticket's status. This includes:

• Allowing users to easily purchase and secure tickets for their desired performances.
• Supporting ticket returns for users who cannot attend, updating availability swiftly.
• Enabling last-minute ticket resale automatically, ensuring that theatre seats are filled as much as possible.

By handling all these processes effortlessly, the ticket management function helps theatres optimize their ticket revenue and customer experience.

User Interface Design

The design of the user interface plays a pivotal role in the theatre booking system. A well-designed user interface ensures that users can interact with the theatre booking system easily and effectively, leading to a satisfying user experience.

• It should be intuitive and straightforward, allowing users to navigate through various theatres and performances without struggle.
• The interface must present seat availability in a clear and organized manner, ensuring users can make informed decisions on their bookings.
• Functions such as booking, ticket returns, and checking current orders should be easily accessible with just a few clicks.

A strong user interface bridges the technical complexities of the booking system, making it accessible and user-friendly for all customers.

Distributed Object-Oriented Approach

A distributed object-oriented approach in the theatre booking system helps maintain flexibility and scalability. In this architecture, each theatre functions as a separate object that operates independently.

• This independence means each theatre can handle its own bookings and updates, reducing bottlenecks in the system.
• The modular nature of distributed objects allows new theatres to be added to the system with minimal disturbances to the overall operation.
• This approach also supports fault tolerance, as issues within one theatre system do not directly affect others.

By implementing a distributed, object-oriented approach, the booking system can effectively handle a national scale, ensuring seamless operation even as demands fluctuate.
