Small & Simple architecture
It seems Scott Hanselman was a little ticked off by seeing too many connectionstrings in the code. 🙂
He wrote a very short, but very clear article/post about the different layers and what they should and shouldn’t do. If you think you know everything about architecture and their layers, it’s always nice to just copy-n-paste his story in some technical document, so the n00bs that have to read your document are clear on these as well! 🙂
