I would like... for example...:
* Instantiate directly dataset nodes to specific classes (for
example to have an inheritance hierarchy between them)
* To be able to have "calculated fields" in a dataset (for example,
a field that is the concatenation of two other fields, or the
result of an operation, for example, the sum of the values of
* Have object notation: person.deparment.name (is it possible?)
Basically... what i want is to find the way to have some kind of data
handling abstraction... (it seems that the dataset is for that... but
guess I want to know mode about its capabilities)
My main problem... is that, currently if I want to write code to access
data from SOAP, or plain XML or JMI, the code is very different in each
case... and I would like to create some kind of abstraction layer, so
that if at the beginning I use SOAP, and later I change to one of the
others... I don't have to make lots of adjustments... I guess I am
trying to create some kind of DAO/ORM framework for Laszlo... any hints?
Thanks a lot everybody for you answers!
