Approach	Description
Visual InterDev	Puts all the presentation-tier code along with the layout details inside Active Server Pages. Productivity is high due to WYSIWYG nature of the page editor. It’s fast and easy to change pages on a production site.
Binary Fanatic	Uses ASP script as little as possible. Puts all presentation-tier code inside one or more COM-based DLLs. Generates all page content and layout details dynamically.
WebClasses	Uses the same approach as binary fanatic, but uses the WebClass framework as a starting point instead of starting from scratch.
