Thanks for such videos, hoping for more such videos soon

Hello Ma'am or infact I can say Pratiksha as in IT culture we don't call Sir or Madam anyone. Your video is truly nice & the way you taught and expressed this concept is really great. There are many tutorials and the tutors teaching on YT refer to themselves having experience in top product based companies. But, from your teaching style, I am influenced and your concepts are really strong and it definitely looks like you are working with Amazon and you can really switch between product-based companies.

Excellent and crisp explanation.Just a few questions.1. Why do we need a cartDb? As this is a temporary data and will not be required once an order is placed for the cart. It may be redundant in that case. But it will be useful if the user wants to retrieve the cart information later on. In my opinion, we can manage both Cart and Orders using a single DB.Same goes with inventory DB and order DB.We can use a single DB to manage both.And we can manage recommnedations using the search service itself as the source of truth is the search history db managed by Search Service.
@pratikshabakrola Жыл бұрын
When user add items to the cart but doesn’t complete the order and leave the site, you can keep those items in the cart when they revisit. I agree with your suggestion that you could manage that in the order database, by simply adding an additional column to indicate whether the order has been placed or not. I don’t think it’s such a good idea to have one database for inventory as well as orders, they’re essentially two different types of of data. When they’re separate, you can archive historical orders but if you maintain inventory in the same table, design is not as clean.

Very Basic design. Most of the time talked about the DB designs. Looking for the how product search is implemented, order transactions which will be interesting for the interviews. You talked about the scalability but didn't about the how you are going to implement via deployment or maintenance point of views
@pratikshabakrola9 ай бұрын
Thanks for taking the time to share your thoughts! Normally, your system design interview will be for one hour. If you remove the initial introduction with your interviewer and last few minutes for Q&A, you will have only about 45 minutes for the actual interview. If you can cover the design , elastic search, transaction processing system, plus deployment and maintenance point of view, Go for it!! But if you take all of that in requirements and don't complete the design, it reflects poorly on time management skills. Also, if you take on too many features, you may not be able to provide in-depth explanations. So, choose wisely!!
@bhetobangalijd9 ай бұрын
@@pratikshabakrola normally, user management is same for all the use cases. In interview, if its specially mentioned about ecommerce then you should focus on ecommerce related topics. Like how you are going to design your product catelog, cart management, order management. Covering only user management for the sake of time killing its not a good idea. 1hr is a huge time, to showcase your skills you should concentrate the other aspects apart from user management. Wisely from an architect POV, interviewers looking for how you are handling scalability, resiliency and how you are bringing out of the box ideas.

Thank you for putting this together. A couple of notes. The video seems sped up at certain parts and normal in others. A little jarring to follow. Personally, I see Search/Cart/Order as separate services. I would expect a direct interaction from User to Order or Cart Service and not through Search Or Reommendation.
@pratikshabakrola9 ай бұрын
Hi, Thank you for taking the time to share this. It usually takes a few hours to film the whole video and i sometimes talk faster(especially when i get tired). I will pay attention to the pace at which I talk. Regarding the Search/Cart/Order service. There are multiple right ways of doing something. So, You can have them as a separate service if you like. My thought process is: You saw a recommended product on your homepage and decided to add it to cart or You want something, you will search for it and add it to the cart from the search results. Hope this helps! Thanks,

I loved that you built the architecture following an ordering of usage (search to order status) and base implementation to improvements (services, DBs and then caching , archives) I just had one concern. Is it good to have one single service touching more than one database ? Also maybe horizontally organizing the system design in layers like web tier, app tier, data tier would improve the readability of the overall architecture by avoiding entanglements in the design. Thanks very much for sharing your knowledge :D Please post more of that content!
