In this blog post I will highlight an overlooked feature in my SQL Server Compact Toolbox (Visual Studio add-in or standalone), the ability to create interactive relationship diagrams of SQL Server databases. And in combination with the free, open source DB>Doc for SQL Server, you have a full suite of documentation tools.
In order to create a diagram showing tables, columns and relationships for your SQL Server database, install the Toolbox.
Right click the root node of the Toolbox window, and select “Create SQL Server Database Graph (DGML)”:
Select the database that you want to diagram (the tool needs SELECT permission on the system views in the database)
You can also select to diagram only a subset of the tables in the database:
You will be prompted for a location to save the DGML file, enter this, and click OK, and Visual Studio will show the generated diagram in the DGML viewer, that comes with Visual Studio 2012 Pro or higher:
The viewer is quite advanced, from the Layout menu you can choose between various layouts of the dependency graph, and other advanced features to analyse the graph, for example. From the viewer you can Share as Image or XPS:
Click on a table, and select the down arrow button to expand the table into columns, and refer to the Legend also displayed (via the Legend menu item in the viewer):
More information on working with the graphs is available on MSDN:
To create HTML/XML based documentation of your database columns, you can use the open sourceDB>Doc tool. The main idea [of this tool] is to serve as a complementary tool to database diagrams, focusing on columns in tables and their meaning (common database diagrams focus to entity relationships).
I also use this tool for the documentation feature in the Toolbox for SQL Server Compact database files, which produces output similar to this:
Happy documenting! And feel free to provide feedback athttps://sqlcetoolbox.codeplex.com/WorkItem/Create
