The Architect edition of Delphi 2009 includes everything in the Enterprise version, as well as data modeling and design capabilities from Embarcadero ER/Studio Developer Edition. Embarcadero ER/Studio is an industry-leading data modeling tool which helps companies discover, document, and re-use data assets. With round-trip database support, data architects have the power to easily reverse-engineer, analyze, and optimize existing databases. Productivity gains and enforcement of organizational standards can be achieved with ER/Studio's strong collaboration capabilities.
The Architect edition is of interest to the same developers who are interested in the Enterprise Edition, but who want to do database design and management in a highly productive environment.
