Subject [RT] Direct Form->SQL mapping through OJB and DynaBeans
Date Fri, 31 Oct 2003 15:25:17 GMT

Some people to which I demonstrated Woody and Flowscript asked me how we 
can directly map forms to a database.

Yeah, I know that architecturally having intermediate domain objects is 
better, but it seems a bit overkill when what you need is just a simple 
CRUD front-end to a database and have no additional logic.

Writing a SQL binding for forms seems a complicated beast to me (maybe 
I'm wrong as I'm not very fluent in SQL), so I was thinking of using 
tools that would to the dirty work for me.

And here comes (Antonio, you'll be happy!!) OJB, which AFAIK can persist 
DynaBeans [1].

So what about adding a getBean() to the widget interface that would 
return a DynaBean wrapper of the form widgets? A simple OJB mapping file 
and voilĂ , persistant forms!

What do you think?
