Hi ! I don't known if it's the right news group for this message, but if someone as some ideas.. The problem is: I have a Model A (a tree model, or some other data structure) made of types t1, t2,...tn. I want to transform this model, in another model( Model B) made of some possible NEW types t1', t2', tn'...build with the original types t1, t2,...tn. - Is there some already framework to make this kind of transformation ? - For example, if someone known the ObjectBridge ODMG framework: it's a Transparent persistence framework for Java Objects against RDBMS. (an O/R mapping framework) What do you think about re using, this kind of framework, because O/R framework already made this kind of transformation to save classes to possible multiple tables. - What about Exolab Castor ?
