Getting to know the DB of SharePoint 2007

When I was searching on SharePoint 2007 database analyzers initially I got so many other products including links to main SharePoint Migration Tools available. Those tools do provide analyzing to a certain extent but it can be costly due to licensing issues.
So my friend suggested to refine my search! I did! And the results were marvelous :)
The results I got were a basic tool Microsoft provides free of charge which, amazingly, gives a whole load of information on the DB.

The tool, which is SPDiag v1.0, is included in the Microsoft SharePoint Administration Toolkit v3.0, available for download at the following locations:

• Microsoft SharePoint Administration Toolkit v3.0 x86: http://go.microsoft.com/fwlink/?LinkId=141504
• Microsoft SharePoint Administration Toolkit v3.0 x64: http://go.microsoft.com/fwlink/?LinkId=142035

Documentation for SPDiag is available from those download pages as well.

Searching about SharePoint 2007 large List migration

 When migrating from SharePoint 2007, moving large lists can be a problem. In the internet it is a bit hard to find information about this in one place. I had to go through this trouble while I was researching on SharePoint 2007 to 2010 migration.
 When I was searching with the keyword "database analyze" search engines return a host of posts that are related to basic Ms SQL Server administration commands and scenarios.
 However the Bamboo SharePoint Analyzer does give an idea about the Database in SharePoint in a somewhat higher level. Thus does not provide much details.
  So the effective way is to search using keyword " large list migration in SharePoint ". This is effective because SharePoint data is stored in Lists, and technically a SharePoint database is a "List".
