Hi Dmitry,

Based on our implementations, I would recommend that you stay away from using objects to hold data. This decision becomes very critical when you get to 100MB+ data objects. And if you intend to hold these objects in a collection, then you're even more in dire straits. We basically hold what would be comparable to the DataSet class in .Net in memory and it is literally killing our application. We had to write code to clear the memory buffer. Performance is not optimized as well.

Data objects are very useful when used in small sizes. One of the beauties of an object is that you can reference them elegantly compared to arrays (ie. objProduct.ProductId compared to aProducts[1,1]).

Again, this is just based on our implementations.
