Servantt is the WinMerge for comparing SQL Server Databases to Version-Controlled Scripts.

It allows you to:

  - Reverse-engineer your Database objects into a standard 
    and logical structure in file system
  - Compare Database objects to the Scripts folder
  - Differences can be either applied to the Database (updating objects) 
    or to the Scripts. 
  - In a single click you can launch WinMerge 
    and easily compare the Scripts to the Database

It supports and encourages best-practices in software development:

  - Keeping Database objects under version-control
  - Removing access rights from developers
    on production environments
  - DBA review of changes in procedures/views for performance 
    bottlenecks and naming standards
  - Naming objects using fully qualified identifiers 
    and correct delimiters

Any suggestions (or criticisms) are welcome.
