CROW - n-Tier Architecture

 

The Control Room Operations Window is implemented using a true best practices n-tier solution architecture, which separates User Services, Business Services, and Data Services into distinct layers. As with any n-tier implementation, this architecture provides the benefits of flexibility, scalability and maintainability.

The User Services tier provides both client-server and web-based components. This architecture provides high-speed access to Control Center operators who require high performance and reliability; and web-based access to users across the enterprise. It also provides a secure standards-based Web Services API. Since all three User Services components share a common Business Services layer, you are assured that business rules are implemented consistently in all three User Services components.
