web applications: what is the correct way to realise web applications

tercoz has asked for the wisdom of the Perl Monks concerning the following question:

I am writing a website.

I use CGI, HTML::Template, CGI::Sessions, DBI

my working www folder structure is

cgi-bin : contains all *.pl scripts
html : html, pictures, JS, CSS
SQL : *.sql files to create databases, and play with queries
templates: all html/css templates of the application

the logic of work is next:
When I want to register I run register.pl, which uses query->prepare("sql query") functions to write to the db inside this script, create session with sessions.pm, show register form with register.tmpl template. When I want to show admin form I run admin.pl which does the whole job, sessions control, database operations, it shows admin form and so on
So the logic is that each separate pl file is responsible for his own single page of my website

Question: why do I feel that this method of writing web site (web application) is not normal, and how to write web application with correct arhitecture? What -is- correct arhitecture?

I think there is not the best way how to do it. My experience is that if you firstly write software requirements, i.e. WHAT it should do (not HOW), in exact details, choosing proper technologies, data organization and coding become more clear. Btw, your folder structure is good, in my opinion. - If it fullfils your requirements :>) You can inspire with Bugzilla project, also using CGI scripts and HTML::Template.	[reply]

Good point. I often start with a question HOW Gotta look on things at the other angle))	[reply]

Perhaps this would help http://secs.ceas.uc.edu/~cpurdy/sefall11/ReqsDoc.pdf I never had believed such documents, perhaps never had understood. But praxis forced me to understand :>)	[reply]

Question: why do I feel that this method of writing web site (web application) is not normal You have got a screw loose :) and how to write web application with correct arhitecture? What -is- correct arhitecture? There is no correct architecture :) I've only read a little about "software architecture" , but I'm pretty sure what you've described is called design, not architecture See these links, and these and these links	[reply]

There are many rumours about MVC and that things like cgi::application force a programmer to follow definite rules as he design his application, I have read about this way of making applications and didn't find any advantage in this way. MVC that's what make me curious, is it really better than simply using single scripts for single tasks	[reply]

MVC that's what make me curious, is it really better than simply using single scripts for single tasks Reading is never as convincing as understanding :) and the right kind of exercise can promote understanding I remember reading about MVC before I did any OOP, and I didn't see any benefits either :) Its like trying to understand the benefit of stick-frame-housing-in-earthquake-zones when you're living in a cave :) You mean to tell me I have to cut trees down, then nail them ... but the cave is right there :) Based on this thread along with is this script secured enough from internet attacks, I believe you need to read/write more code, more programs, more big and OO programs, before you can appreciate the benefits of MVC or scaffolding like mojo/dancer/catalyst/cgi-app Oh look, a single script for a single task, without MVC or OOP, admin.cgi `use MyShinyPoodle::Admin::CGI; MyShinyPoodle::Admin::CGI->run;` [download] Now you can test MyShinyPoodle::Admin , and it doesn't depend on any html templates or protocols like CGI See also Object Oriented Orientation Good luck	[reply] [d/l]
