I hope you'd like an opensource tool I've made called Nautilus.

Nautilus (sqlserver) v1.0.2
Navigate your SQLServer 2000 database
http://sourceforge.net/projects/nautilus/

WHAT
-----
Nautilus is a tool for developers, advanced users and auditors.
The main objetive is to find information in a SQLServer database without knowing too much about it. User can search tables and records with no SQL typing required.
You can also browse related data following the foreign key links or search a value in the whole database.
