Michael Paladino recently presented on a data acess tool called SubSonic.  This is a really handy project that integrates into your ASP.NET web site and gives you quick access to your database by automatically generating objects and query methods, as well as providing IntelliSense and namespaces for your database tables.  I started setting our web site up to use it but ended up going with a full-feature blog solution instead, but the next web site I make where I need to do a lot of customization will definitely have SubSonic on its backend!
