Found: The missing framework for enterprise .NET applications. There is a better way, and savvy developers have been using it for over two years: Borland Enterprise Core Objects II (ECO II).

ECO II is a highly productive framework for distributed or standalone applications, which uses Object Query Language to provide a clean separation of business rules from implementation details. ECO II efficiently manages databases using sophisticated caching and transparent server clustering.

I quote from unbiased soure at Borland.

I've seen ECO I. It's nice, but cumbersome to use when you don't use any winforms controls (as they appeared to use these for data object storage )
