Hey Guys, I have an OK handle on document types, templates and generally how umbraco works, and I can use it to create a fairly flexible system to control the content, but now I want to do more with umbraco.

For example I want to create a simple system where a user can enter a serial number click a submit button then I want display a record in a database. I also want a site admin to be able to login to umbraco back end and manage the records in the database, i.e CRUD. In the past I have done this using the nodes in umbraco and every node represented a record, this was ok for that implementation because I would have a max of say 300 records, but this time I have thousands.

Where can I find information on developing applications that do more than just CMS with umbraco. Should I be using user controls in back end to interact with the database and what is the best approach to get the data out again on the front end.

I want to build solid applications with all the principles of SOLID... how can umbraco fit in to all of this?
