The Business Case for System-Wide Information Management

In today's National Airspace System (NAS), when an application requires information from another application, a custom application-to-application interface is built. This results in an increasingly complex system, where applications are tightly coupled and expensive to develop and maintain. System-Wide Information Management (SWIM) addresses these shortfalls by implementing a shared infrastructure for managing NAS information. SWIM is based on a service-oriented architecture, a fast growing trend in information technology. It will help the Federal Aviation Administration (FAA) meet the information-sharing needs of the Next Generation Air Traffic System (NGATS) and the federal government's E-government Initiative. SWIM will reduce the cost, complexity, and cycle time for building new applications and help the FAA implement SWIM-enabled applications that increase FAA and user productivity.
