seems to be good site if some one would like to play around with database online.. comes with starter databases....

For example...

* A membership directory for your club
* A list of movies in a shared collection
* Restaurants that you need to try
* Recommendations for a book club
* Articles for a research project

Features

* No logins. A secret URL gives editing access to the database
* Create new types of items, or use the samples provided by Lazybase
* View lists in many ways, on maps or on graphs
* Link types together (for example have orders linked to customers)
* Easily add a view into your Lazybase database to your own website
* Bookmarklet generation, RSS feeds, and more
