This thesis contributes to the US Navy forces maintaining information superiority in a Network Centric Warfare environment. This research develops an Extensible Markup Language XML-based Web Publishing Framework, which supports the Web Enabled Navy (WEN) architecture infrastructure. The Web application framework easily supports connections to multiple distributed databases and XML-based presentations, specifically three-dimensional (3D) simulations utilizing Extensible 3D (X3D) and Virtual Reality Modeling Language (VRML). This research evaluates and demonstrates the functionality of an XML-based Web Publishing Framework. The research demonstrates ability to connect to both XML and non-XML heterogeneous database systems and provides a framework for the distribution data across heterogeneous systems. The system supports usage in multi-tier network architecture. 3D modeling and simulations provide insights into operations that cannot be realized using standard two-dimensional (2D) renditions. The development of an application server to support 3D modeling and simulations for operational planning will provide the U.S. Navy a better way of realizing operational limits. This research addresses the Web publishing framework, which supports the development XML based data exchange, and the development of an Î²on the flyÎ³ X3D simulation presentation. This research evaluated the functionality of an XML based Web framework, which allows for the separation between application programming and Web presentation. This incorporation of a Model, View, and Controller (MVC) design approach provides a clean separation between different components (logic, presentation, and data) of information and the programming functionality. The Web framework addressed ability to provide a framework for the distribution data across heterogeneous systems.
