I know at present there is no built-in facility for creating diagrams in SSDT for SQL 2012. Is there any 3rd party plugin available that allows the creation of diagrams? Or indeed, does anybody know if/when the functionality may become available? I've so far not found anything via Google on 3rd party tools and only the vaguest suggestion that the feature might be coming Thanks
Everything I've heard there are zero plans to make diagrams a part of SSDT. I don't know of any third party tools that will plug into SSDT and do it either. If you really need a diagraming tool, Embarcadero ERSTudio is excellent.
