Just noting that that seems like a poor way for the interviewer to conduct the interview.

The question that was asked called (IMO) for general appoaches; you instead, talked nuts-and-bolts (a "hash").
Perhaps you didn't ask enough questions before answering the question:
24x7
Batch versus online versus real-time
Desktop client, web client, web server, application server, database server
Web services, message queues, task scheduler, SQL agent, system services
3rd Party integration
Devopment stack
etc.
So, you should have answered: "It depends".

I'm asking about reading material. Not a critique on my interview. The interviewer went into the nuts and bolts. I just want to learn about these nuts and bolts.

That's the point; it's a "general systems knowledge" that let's one ask questions to get to specifics.
I'm not aware of any other "blue prints"; and since you didn't say specifically what was asked, one can only "generalize".
There are patterens for online systems, web apps, real-time, atomic, sessions, etc.
There is no single source that covers "all" situations.
It's not always about "having an answer"; it's also about how one goes about "finding" an answer.
There's nothing wrong with trying to "steer" an interview. I'll do it if I can; even if it's about "hobbies" (did it; got the contract).

Hey everyone,
I want to work out a concept for a platform which will help users to collaboratively plan a project. The platform should consist of:
- A responsive website that shows changing content without complete reloading
- Where multiple users could input text at the same time
- Processing of the input with content based filtering algorithms
- A database to store all the inputs the users made
I know how to program a website and I have basic knowledge of java, but I don’t know which technologies would work together the best?
I thought the following parts would make a solid base?
- Linux Server with java (for the logic part)
- MySQL
- Website (JavaScript, HTML, CSS)
But when I search the web for the missing pieces in between I always find other keywords like Ruby on Rails, Node.js, hibernate… and I’m seriously confused at this point.
Can someone help me with my Problem and maybe suggest a better concept, because my lack of experience makes it hard to connect all the pieces to one working platform?
Thanks in advance

Technology is a tool not a solution. You want to build a house and you are looking at nails rather than figuring out where the doors and windows should go.

You can research how online games and shared desktop systems work. Basically, very basically, they send messages from the originating client to the server and the messages are distributed to the other clients. There are many optimizations involved in the message flow so that it is smooth rather than jerky.

If you do not know how to use a database at all and you want to use a database then your first task will be to learn how to use one. And use it with java.
You will also need to design (NOT code) what the data structure will look like that is "saved". Once you design it then you need to create a data model which can used to drive both the database entities and the java entities (often similar but not necessarily one to one.)
If this is for yourself then you might want to start with a chat program that also stores the chat history. And then allows a user to review that history.

Thank you for the great answer!
The whole platform is part of a university project and some students are going to try the whole thing out at the end. The students will write down questions to investigate a given problem. These answers should be stored and filtered.
I worked with a database before, but just with basic SQL queries on a DB2 database. And I never integrated one into any software project. The tip to design the database in theory is very good I will do this asap.
My main problem is that I don’t know how to properly connect the website with the server and which programming language to use on the server. I found some architectures with Java Beans, Java Servlets and JSP but I don’t know how these should/would work together.

Based on my experience, in college, keep it simple. No extras. If you get done way early then you can add extras.
Do you consider that you are better in one language than others? Then use that one.

Fortunately there are many examples of that on the internet - but keep it simple.

Forget all of those. Try searching for examples using the following in google. (There are others besides codeproject of course but finding actual examples can be more difficult.)
jdbc site:codeproject.com
Why forget those specific ones? First because they probably are not as relevant now as the once were. There is some concepts there to learn but I suspect there is too much that isn't relevant. Second anything that accesses the database in java, no matter what sort of pretty facades they wrap it in, must still use jdbc. So learning that is always useful. Third jdbc matches your skill set in that it basically just SQL in java.

we have a vending machine project and we need a help today
In this project, you will design a vending machine that will accept at least two different coins (5 kr, 10 kr, 25 kr, 50 kr, 1 tl) and will output at least 2 products. For example, one group can choose 5 kr and 10 kr, and dispense 2 different products while another group might decide to use all the coins, (5 kr, 10 kr, 25 kr, 50 kr, and 1 tl) and dispense 3 or 5 different products. Groups are free to determine the count, the name and price of each product in their projects. For example, you can choose gum (20 kr), soda (35 kr), and chocolate (65 kr).

Guys, I am looking for a Design & | Architectural suggestion for my Application which should work for different types of clients: (Thin Client(Browser), Thick Client(WPF), mobile application) and DataBase can extend to Cloud in future
Proposed:
MVC Pattern, Client-Server architecture
Presentation Layer: HTML5 or WPF?
Business Layer: C#.Net, WCF Services
Data Layer: LINQ, ADO.Net
Database: ?
I need a suggestion on two things
1) Is WPF suitable for all 3 client types? is it easy to make WPF to Web client through xamarine or cardova or any other software alike. if yes pls suggest
2) Which Database service would be suitable for my future extensions to Cloud. And currently which Database can be taken, I will get some simple text data(Unstructured) as input and should process and display as structured in graphical chart way.
Thanks in Advance

WPF is not going to meet you requirements.
If you need a web UI then forget having a desktop version, there will be little benefit to the user between WPF and a browser solution (and I'm a WPF developer).
Your service should probably be Web API and no WCF.
Depending on your requirements there are lots of good databases to pick from. If it is purely data the a relational database like SQL Server, MariaDB or MySQL will meet your requirements.

Thank You Mr. RAH.
I was thinking about WPF Client because My Application will be used by many (more than 90%) by a single client and on a single PC. And A little customers want it as Web So in my view my application should support both Thick and Thin to support all customers
Web API mean REST API? Ok I will check that Thanks.
Please guide me on client and easy transferable DB for future Cloud based application too.
Many Thanks for your response

Your choice but the same client will not support both so you will need to write 2 UIs

some plzz brief me what is micro service and how it is different from web service developed with asmx or wcf/web api ?
how to develop a micro service with web api. explain a micro service with a small example.
|
|
|
|
|
|
i got it from your link as follow
Essentially, microservice architecture is a method of developing software applications as a suite of independently deployable, small, modular services in which each service runs a unique process and communicates through a well-defined, lightweight mechanism to serve a business goal.
normally we develop a web service which can do lots of task and when we break our web service into smaller independent web service which will communicate in each other then it will be called microservice ?
microservice is so easy.......i have a doubt ?

A "micro-service" (IMO) is something like "get the current local time" or "temperature".
If I got the time AND the temperature, is it still a "micro-service"?
Micro-services may not be as easy as you think: defining what should be in this service; and / or preventing function creep ... going from a snack, to a full-meal deal.
Service bloat?

not clear the way you explained.
please come with a easy example to define micro service.

This may be viable when using Web API but not for WCF, web api is a URL call and connecting to a WCF service a whole different beast.
I have a monolithic app that incorporates a number of modules all coming from the same WCF, I wish I had broken it into multiple services life may have been quicker if not simpler.
