PS: This is not the real architecture of any such platform. This is my take on how I would answer that problem.

#codekarle #systemdesign #airbnbsystemdesign #system #design #interview #amazon #faang #airbnb

I have explained about the system design and architecture of Airbnb.com or Booking.com. Below is the scope of the presentation.

A) Create Guest/Host Account
B) Search lodging
1) How search index is updated dynamically after room is reserved. (Room should not be visible in search)
2) Ranking infrastructure for better search results (Good ranking, good conversion)
C) Become a host
D) Reserving/Booking rooms (Avoid two users booking the same room at same time)

There is also a screen dedicated to database design for Airbnb and explained in detail.

Following are the restful API's in the System design

guestAccountService ( app_key, username, password, address)
hostAccountService ( app_key, username, password, address)
becomeHostService (app_key, location, availableFrom, availabeTo, roomDetails, description)
searchService( app_key, location, checkin_date, check_out_date, guestCount)
viewRoomService( app_key, room_id, checkin_date, check_out_date, guestCount)
viewReviewService ( app_key, room_id);
reserverService( app_key, creditcardInfo, room_id, checkin_date, check_out_date, guestCount)

Also, there is an extensive talk about the search services with ranking of the search data. Finally, I demonstrated how to use AWS services to build a system for Airbnb.
Understanding the ranking will also help you to build recommendation system for Hotel booking.

Common tech stacks used to build these types of system is also discussed.

Programming languages for web app (followed by the relevant frameworks): HTML5/CSS3, JavaScript (Node.js, React, RxJS, Angular), Python, Ruby (Ruby on Rails).
Programming languages for mobile app: Swift (for iOS), Java (for Android).
Data management systems: Cassandra, MySQL, Oracle, PostgreSQL.
Cloud platforms: Amazon EC2, Amazon S3, GCP
Analytics and insights: Google Mobile App Analytics,
CDN services: Amazon CloudFront, Open Connect, Akama
Geolocation: Google Maps API, MapKit/Core Location frameworks (for iOS).
Messaging: PubNub, Twilio
Photo storage: Scene-7

Here are 5 Tips for System Design interviews. They are helpful when preparing for a System Design interview.

1. Don't get into details prematurely

2. Avoid fitting requirements to a set architecture in mind

3. Keep it simple, stupid! Remember to look at the big picture and avoid too many hacks when solving.

4. Have justifications for the points you make. Don't use buzz words or half hearted thoughts in your design.

5. Be aware of the current solutions and tech practices. A lot of solutions can be purchased off the shelf which simplify implementation. You should be able to argue for a custom implementation with it's pros and cons.

Have these on the back of your mind during you interview, and all the best!
Here are three major points evaluated during the interview:
1. Clarity of Thought

a. Express your thoughts in a clear manner.

b. Justify your decisions. Critical reasoning and argument are key to a successful software design.

c. When faced with a problem, use standard approaches to mitigate it. For example, say you are faced with an availability problem. State that replication and partitioning help increase availability in general, and move on to offer a solution.

d. Don’t make points without thinking them through. Half-hearted attempts at solving problems are frowned upon heavily.

2. Know about existing solutions

a. Stay up to date with the current solutions in the market. This includes products and design practices. If NoSQL is being adopted left right and center, you need to be aware of it.

b. Know when to pick a solution vs. building something custom. If you name a product, you should be (generally) aware of the features it provides.

c. Design practices enable you to meet custom requirements. Examples are decoupling systems, load balancing, sticky sessions, etc…

3. Flexibility

a. Switch your targets as the requirements shift. If the interviewer wants to know about one particular part of the system, do it first.

b. Never have a set architecture in mind. We all try to fit requirements to a system, but only after it has been shaped by the initial ones. A rigid attitude creates a brittle architecture. It will break before you do.

c. Take a step back at times to make adjustments to the general architecture. Being focused on one part can narrow our vision and bloat those areas. There will be components which can be extracted out and extended to the rest of the system.

Hi,

In this video I tried to come up with the low level design of one of the most frequently asked questions, designing a Hotel Management System. This is the part 1 of it. Here I have discussed how to gather requirements, What different kinds of requirements are and how to come up with actors and use cases. Then I also drew the use case diagram of it.

Learn how to set up your online booking site with Square Appointments.

You can learn more about getting the most out of Square Appointments at squareup.com/help.

Transcript

You can use Square’s online scheduling software and tools to allow your customers to book online.

There are a few ways to get started. You can:

Share a single-page, auto-generated online booking site
Set up a full-service custom website with Square Online Store
or, you can embed a booking button on your existing website

The first step is to head to your online Square Dashboard, click Appointments, and under Online Booking, select Booking Site.

Your auto-generated booking site pulls from your available services, staff, and location details. You can share your booking site URL through email or social media—so customers can start booking right away.

Just keep in mind, if you have multiple locations with your Square account, each location will have a unique booking URL, but customers can still select a different location directly from the booking page.

While the online booking page is quick and easy to set up, if you want to fully customize the booking experience and enhance your online presence, you can set up your Square Online Store. Just head to the Online Store tab and click “Get Started”. Import your services and design your website.

Lastly, if you already have a website, you can quickly integrate Square Appointments by embedding a booking button. You can customize your booking button to fit the branding of your website by updating the call to action text as well as the button color. Just copy and paste the embed code to add it to your website. The booking widget will automatically resize to fit your website.

The steps for embedding the booking button in your website will vary depending on your provider.

To learn more about Square Appointments, head to square.com/help and search keyword “Appointments”.

Learn how to make an appointment booking website step by step with no step skipped.

By the end of this video, people will be able to schedule appointments with you on your website. We will be using WordPress which is the best way in the entire world to create your website.

It's perfect for consultants, dog groomers, lawyers, accountants, doctors, therapists, dentists, dermatologists, salons, trainers, setting up meetings, or zoom meetings-- or anyone who needs to make an appointment with you.

This video will let people make an appointment with you in the most efficient and simplified way possible.
