Check out Dabble DB from Smallthought
by Tom Carroll
I was reading a post from Tim Bray about Dabble DB by Smallthough. So I went and watched the screen cast demo they have up on the site. Wow, very cool. Dabble is a collaborative data management, authoring, and publishing web application (I know that description doesn’t do Dabble DB justice). The application lets you copy and past spreadsheet data into the app. It lets you create associations not explicitly present in the original data. It lets you save views of the data. It publishes data in RSS and a lot more.
Just go and check it out, you will be impressed.
