That is where I'm having problem with. You now require the caller to

than simply do a chain? I think this DB layer will eventually evolve
into a monster. I don't see how this could save time in the long run.

I have to admit I'm not following you. The caller knows that he wants a
MasterFile record:

MasterFile_Initialize(keyValue);

He then knows the fields he wants to work with:

MasterFile_GetName();
MasterFile_GetAddress();
MasterFile_GetZipCode();

etc. etc.

What is the "format" you are referring to? The prototypes will tell the
developer what the return definitions and set values are, so he doesn't even
technically need to know the database format.

And, I don't know how else to express this, but if you think this is about
making it easier then you are missing the point. Yes, I believe that long
term maintenance is easier: but the initial development is not. So "easier"
is not necessarily the target here: "better" is the goal, with a side
benefit of simplified maintenance down the road.
