Hi Alan,
Can you quantify this issue please:
"The disadvantage to the Database Objects that they bring the entire
database record in when they fetch a database objects. Huge amount of
overhead."
In a general sense I would've thought this is a positive behaviour, that
actually reduces I/O, supports caching, doesn't require a persistent
connection to the DB etc etc. What is the issue you're seeing?
Regards,
Brenden Conolly

I agree with everything you are saying except "Why try to achieve database
independence". Huh!!
That is kind of like saying you prefer to stick a sharp stick in your eye.
Without database independence, your database is locked. Any changes means
recompiling the whole word which, of course, nobody does.
Also, when we talk about about the encapsulation it is not an either or
situation. The is nothing to keep you from:
Applications Calling
Business Objects (Customer, Product) Calling
File Encapsulation
I am just saying with SQL not much reason to be creating File
Encapsulation.
In our new Java stuff written in a framework we have a:
Application calling
Business Objects Calling
Database Objects.
The disadvantage to the Database Objects that they bring the entire
database record in when they fetch a database objects. Huge amount of
overhead.
