SQLRaptor is a MSSQL compare and documentation tool.
It is constituted of two tools: a documentation tool and a compare tool.
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 HTMLHelp file
(.chm), or in a RTF file or in a website. You can even add your comments to tables,
columns, views and stored proceures directly from the HTML generated (see add comments
to DB objects section in the manual).
