A database designer in simple terms designs the database layer of the eventual application. Like the initial crew on a home build site the database designer (architect) is responsible for laying the foundation of the project. The architectural structure and integrity of the database is one of the most important key elements to insuring a solid application build. While the application layer can be re-worked easily the database layer can not. Many attempt changing and molding the database to fit a 'floating' or changing requirements vision however this always turns into a mess. Without a proper FOUNDATION (the database in this case) the application will ultimately fail to meet the performance and or functional requirements of the project and often will cause the entire project to fail. In closing; the GOAL of the database architect is to construct a database environment that maintains its data elements reliably, provide a high performance architecture that will scale with the business model, provide a construct in which data integrity is maintained, and employ best practices to insure a stable and secure environment.
