SqlRaptor lets developers store comparisons into their database ( or on disk files) to ensure the integrity
of team development efforts.
The MSSQL documentation tool produces CHM, HTML and RTF output.
Essentially, the documentation tool uses SQL-DMO calls and ad-hoc queries to reverse engineer your database, and then places all of the documentation in a HTML Help-formatted file, or in a RTF file.
If you want to add a comment to a column you can call an editor window directly from the HTML help file, this window connects to database and insert the comment in the right table (sysproperties).
With SqlRaptor you have two utilities in one product.
