I've been using ERWin for about 10 years now. My version is ancient and I do not think it's worth paying the rediculous upgrade price!
Problem is it's starting to show it's age - I've been using it primarliy for MS SQL.
I wish I could justify Embarcadero's ER/Studio, but I just need something that will allow me to design a DB and sync it.
I've checked out http://stackoverflow.com/questions/674911/light-weight-er-diagram-tool, but nothing fits except schemabank, but a web based tool has too many drawbacks (recurring fees, less integrated, off-site storage of data).
I've also used SQL Maestro for regular queries and DB management, it was ok, but has a few definate shortcomings. Has anybody used the ER designer successfully?
What do you guys use?
