My recommendation is to use class style get/set instance functions for data
hiding requirements.
Explanation.
Encapsulation means data and functions about an object are defined together
as a class. Data hiding is a programming technique that is an indirect
access to a class's data. Data

I respectfully disagree. Points:
1. Class style accessors are too generic unless the object is a
generic object such as a generic transfer object.

My app contains Pages, Modules, Categories and Products, all

For the first part, I'd go with an abstract content object that
doesn't define getContent, and which Module, Category, Product, and
Page all extend. That's where you'd house all the common
functionality, leaving just the 'getContent' method up to the
individual implementations.

Seems to me more like this would be a good use of an interface (which we don't have in Cold Fusion). But you can create a PageInterface CFC that describes the page interface and procedurallyimplement it, that is make sure you have a method for each methodin the interface without a compiler
Would be nice of Macromedia would ad interfaces.
Not for this reason. CF is not a compiled language, and the
typechecking that interfaces do happen at compile time. Bit of a
catch-22, because the checks you want HAVE to happen at a place that
doesn't exist in CF's world.

While I agree that it isn't a compiled language in the same sense that you compile it yourself within your IDE, it is my understanding that cold fusion is itself a cf to java compiler (among other things). So the compile time checking could happen, but not in the same why you would see in java. At

What is the best way to split the

Yes, it is. However, unlike a real compiler, you don't get full
perspective of the app at compile time. When you compile Java, you
have to have all the resources for the whole app available to you so
The type checking is the most important feature, as it enables you to
separate your API from it's implementation(s). Yes, CF could check your
implementation against an interface at compile-time, which means the
first time that CFC is created, but that is less a desire to me as is
runtime type

The problem is with the way CFML is compiled. You can't make those

Are you trying to do pagination? If so, splitting the dataset is

That's close, but it ignores the ordering - if you want them both in the
same order, you can use a nested query. MSSQL syntax shown. Also, I've
added the use of the percent keyword, which doesn't place an assumption on
