My product is rewritten in python placed in the product folder. So yes, it is a
instance of a class.
In the future, I will be storing more data into one instance from other dbase
file (The total columns may vary).
I'm still in the developing stage and this is just a test run to know that is
the length of processing time I'm look at. I want each entry to be an instance
because I'm planning to create other interactive functions (edit and
query(ZCatalog maybe, I'm not sure yet) and more ) for particular info.
I've never thought of using a BTree because I don't know enough about it. I'll
look into it but will BTree still be a better choice than making instance if
I'm going to make interactive functions?
Any other suggestions?

Please name things the right way. A "Product" is basically a Zope/Python
package that contains definitions of classes, scripts, templates etc.
You mean instances of a particular class?

You're creating 110k instances for storing a string and two floats?
If yes, that's stupid idea.
You can persistent large amounts of data within a single instances
by using Zope BTrees.

What kind of processing?
