I'm not impressed with your continual spam. Who cares about this crappy product.

Nobody, apart from the spammers, that's who.

Hello, Joe,

So, What do you think an O/R mapper should be in order to be great product? Do you have a favourite one? What's your rationale?

Accelerating Development with ECO II (Enterprise Core Objects)

Enterprise Core Objects provides a rapid design-driven architecture for .NET, speeds development, improves quality, and increases the maintainability of complex Web Services, ASP.NET, and WinForm applications.

Architects can use the model-powered ECO Object/Relational Mapping technology to generate or map to several major enterprise-class relational databases, then later evolve the database based on changes in the design model.

With ECO II, the model is the system. This episode will show just how this powerful architecture can dramatically accelerate the development process and at the same time reduce complexity and the amount of code required.

In this BDNtv episode we will:
# Walk through the concepts of model powered design
# Show how we can visually design our business model using standard UML diagrams, and how that model actually becomes our system.
# Discuss how to navigate the model using the Object Constraint Language (OCL)
# Show how we can then automatically persist our model to a relational database.

What would you think if Tierdeveloper added very sophisticated caching capability (with a caching

server) to our product so you could improve your applications performance greatly and also

cache in a clustered environment. Do you think that might serve your needs?
