Just to clearify, when you say schema view, you are refering to a graphical schema i.e. ERD and not a data dictionary?
I haven't tried yet, but Visio uses an odbc driver and as long as I can set up a connection to the mySql database, it should be doable. Problems will arise when it comes to datatypes and relationships, for the reverse engineering might not translate everything accuratly.
Well, what I want is a picture of the tables and their relations. But any progress in documenting the DB(s), like a data dictionary, would be very helpful. Even just a structured start of one that we can wiki, and people can fill out properly. Which will make an eventual ERD picture usable.
