>I am using arrays as way to pass the information from UI to BIZ/DA objects but thinking about changing to objects (using SCATTER/GATHER). In terms of memory use, do objects require more memory?

About
array ~ 16 bytes/item or more
obj property~ 104 bytes/item or more

Each property of an object has a name,
can be an object and can become recursive ...

Object's Scatter/Gather is more slow,
but it uses a not ordered name match copy,
array uses a fixed ordered copy.

Conveniences consume resources,
this is a universal rule ...
