Pardon my ignorance here, but have you installed or tested a trial of the framework yet? Just trying to get an idea of where you are on the StrataFrame curve 
.To answer your question, generating BOs off of an exsiting table structure is literally a 5 second process. The only reason it isn't completely automated is that we have an interim component (the BO Mapper) that allows you to assign Enums to fields, give custom proerties were approriate (i.e. to automatically handle an encrypted field in the databse), etc. Once you have any of those types of customizations done (which, by nature, can not be completely automated), it is a matter of right clicking and selecting "build" to create the desiginer files and such.
If you don't require those customizations, then it is simply a matter of pointing the BO to the proper table structure (the "5 seconds" I mentioned), and clicking the build button. Very quick and simple!
