What literature to read about standard solutions in web applications for business?

Question

Database

Hello!
What literature do you recommend to read on the topic of architecture and standard solutions in web applications for business? Taught by experience, I try not to write crutches, but I would like to find some general guidance on architecture (business applications), or the so-called best practices.
The simplest examples:
user registration, online users, chat architecture
What would you recommend? Please do not write that insight will come by itself, etc. It has already arrived :) But I want to read some solid source.
PS

It is clear which technologies to use for certain situations, and online users can be done in different ways. And all of the above, I have been implementing perfectly for a long time :)
The question was a little different - is there somewhere a full-fledged textbook or a collection of tips on this topic? This is me to the fact that the tasks are different, and with the complexity of the task, the complexity of developing its architecture increases, which is why I am looking for a tutorial. In universities, by the way, this is not taught.

I'm looking for something like "Perfect Code", but only about architecture.

Answer 1

There is a good book that can serve as both a textbook and a reference book. "Microsoft Application Architecture Design Guide, 2nd Edition" ( download.microsoft.com/documents/rus/msdn/%D1%80%D... ).
If you close your eyes to the recommendations for using Microsoft technologies, then there will be a completely holistic picture of how a variety of design issues are solved, from the highest level to implementation details. The issues related to the implementation of web applications and services are considered, among other things, in the general context of an enterprise system.

Answer 2

online users

SELECT * FROM `users` WHERE `user_visitdate` > NOW() - INTERVAL 10 MINUTE The
question is very unclear. User registration is a trivial job for those who have read at least one book on PL.

Answer 3

Also, I didn't quite understand the question. See how others do it, as an option, the source code on github. Registration \ Online - I agree with trevoga_su , with chats, too, everything has already traveled far and wide, on the hub, for example. You are unlikely to find a solid source with a ready-made implementation of your idea in the best practices.
