If you want to create great looking diagrams with data from the vCenter database look at this demo I’ve recorded with MS SQL Code Factory. It’s a premier Microsoft SQL GUI tool aimed at the SQL queries and scripts development. It is a good choice for everyone who need build SQL statements and edit SQL scripts with a convenient easy-to-use interface. The software provides you with a convenient easy-to-use interface, so it really does not require a deep knowledge of Microsoft SQL from its users.
It also has a Powerful BLOB Viewer/Editor: with MS SQL Code Factory you can view or edit BLOB data in the following ways: hexadecimal dump, plain text, graphical image or HTML page. A graphical representation of BLOB data supports five image formats: BMP, Windows metafile, JPEG, GIF and PNG.
