I finally got a chance to install Microsoft SQL Server 2005 Beta 2 (formerly Yukon) the other day so that I could do some forward compatibility tests on the new XML data type for a project we're currently working on.
I fired up the new Query Analyser (now simply called 'new Query' in the Management Studio) and ran the create scripts for a relatively large database.
First port of call, let's see if they've enhanced (fixed) database diagramming, especially the printing options as I always find when working with large database schemas that it's a great help to print out the entire schema and stick it up on the wall.
Maybe Microsoft's Product Unit Manager for SQL Server Tools Euan Garden is playing a big joke on everyone or maybe he's just being very very clever here with Beta 2 because while looking for the database diagram he got me to experience nearly every nook and cranny of the entire application, learned a lot but found no sign of a diagram. Then Euan got to me do a full search of the new help system... very nice but still no mention of a diagram.
Google finally came to the rescue and I found this info on Marc LaFleur's blog.
The 'Diagram' is GONE...
