Recently I had a client request that I document each of the SharePoint 2013 Databases and Compare them to the SharePoint 2010 Databases. I used Apex SQL Doc to document the databases. Apex is great I think
its the only tool still, that is works with SQL 2012.
Most of the SharePoint 2013 Database Documentation is now available for download. But I have not had time to Post the Comparison or Differences that exists between SharePoint 2010 and SharePoint 2013 Databases.
Also, to keep the size of each download below the 250mb maximum I did not load all of the SharePoint databases at the same time so the documentation does not contain any cross database dependencies.
