Hi guys, I know ASP.NET C# very well. I make a lot of stuff like surveys and custom web applications.
I'm having a lot of trouble wrapping my head around Drupal and figuring out how to do 'special' programmatic things, like searching a list of clients, or creating a web application.
1 - I've been reading books and drupal API but I'm still having a lot of trouble getting started with anything at all. Where does custom code go in respect to pages, modules, snippets...? How do I replicate form X that I did in ASP.NET into a new page in drupal? Etc. It is super hard to wrap my head around Drupal, it seems so large and easy and extensible yet also like it is difficult for me to code. What can you recommend for an ASP.NET application programmer to learn to work with/in Drupal?
2 - Sometimes we write complete ASP.NET applications for clients, and these applications are not indended for clients to go editing them. For example, we will have our entire website in drupal, but inside of that website we will have a place for users to use a special search for database information. We don't want simple website editors and content providers trying to edit this specially coded page(s). How do I handle not wanting clients to edit anything in a Drupal application? Is it handled via page/user permissions? Is the best thing to develop and host an application completely outside of drupal? Is the drupal application it's own drupal instance inside of a drupal website (nested drupals?) ?
3 - Lastly, how do I handle databases? I understand Drupal and PHP are set to work best with MySQL. We have MS SQL databases that are used by multiple applications and would like to use them for new applications as we start using Drupal. For example, we have a Staff directory that feeds ASP.NET reporting application, ASP.NET Staff Listing application, and want to make a new Drupal PHP application that also uses (and perhaps inserts/updates more information into) that database. What is the best/easiest way to handle MS SQL databases and/or MySQL databases being used and updated by multiple Drupal and ASP.NET applications? Would it be easier to have all the applications use the MS SQL databases, or maybe to replicate the databases on MySQL for the Drupal/PHP apps and somehow sync the two databases?
I hope it is alright if I ask multiple related questions in a single post.
