Approved for public release, distribution unlimited / Currently under development, the Global Information Grid (GIG) Enterprise Services (ES) is a suite of capabilities intended to provide improved user access to mission-critical data via Web-based and network technologies. Some of the problems of implementing such capabilities include non-uniform data formats, incompatible run-time environments and nonstandard proprietary applications, all of which block operational interoperability. Web services are specifically designed to address the interoperability challenges of a service-oriented architecture (SOA) such as the GIG. SOAs are networked infrastructures that are designed to facilitate the interoperability of collections of services without requiring service context awareness. Standards-based Web services provide the necessary flexibility and extensibility to ensure information flow is platform, run-time and software independent. The proof of concept (POC) software example developed for this research demonstrates the flexibility and extensibility of standards-based, operating-system-independent Web services. The result is an experimental endeavor to provide a mock operation command center information portal, which provides a notional summary personnel status report to the commander in real-time from a Web service that was originally generated by a stand-alone client/server system. The POC is developed with great attention to open-source technologies and open-standards compliance. The key technologies involved are Extensible Markup Language (XML), the Java programming language, PHP: Hypertext Preprocessor (PHP) scripting language and Simple Object Access Protocol (SOAP). This work demonstrates the benefits of leveraging Web services to unlock legacy specialized applications to enhance the Warfighter's battlespace awareness by improving information flow via a Web based information portal. / Captain, United States Marine Corps

Currently, several models and simulations exist for the purposes of training and analyzing military data. Due to the absence of an agreed-upon standard with which to represent unit data, much is lost during interchange and applications are not maximized. This thesis is a step towards a solution. Extensible Markup Language (XML) technology has been widely accepted as a standard for representing information in such a way that it is self-documenting, self-validating and platform independent. By using the Command and Control Information Exchange Data Model (C2IEDM), formerly known as Generic Hub, and XML it is possible to develop a representation of unit data that is extensible and broadly useable by tactical systems and human operators alike. This thesis approaches the problem exploring the Model Driven Architecture (MDA) and the Extensible Modeling Simulation Framework (XMSF) as possible overarching architectural concepts for a global solution. The C2IEDM is used as the core data interchange model for this research and applies XML technologies, schema and the Extensible Stylesheet Language for Transformations (XSLT) to derive a formatted data representation that is acceptable within the Flexible Asymmetric Simulation Technologies (FAST) Toolbox. The transformation example serves as template for other simulation programs to follow for interchange through the common base model. This thesis shows that by using a common data representation like C2IEDM coupled with the power of XML and XSLT, unit information can be transformed and interchanged between applications. In order to accomplish this, an extensive analysis is done on recently performed and ongoing research as well as the development of exemplars to show how the proposed process is completed. The result of this work is a transformation of unit data extracted from an example C2IEDM instance file that is compliant with the schema for an actual unit order of battle tool used for modeling and simulation. / Major, United States Army

Approved for public release, distribution unlimited / Network-centric warfare (NCW) has changed the way the Department of Defense addresses technological improvements for its military forces. No longer is the emphasis on enhancing the capabilities of a single platform, but the focus is now on networking people, processes and technology to enable knowledge sharing and rapid decision-making. The capabilities required to support network-centric operations (NCO) in the NCW environment must be supported by new, innovative networked communication technologies. There are many sources of requirements for these software systems supporting NCO, which may increase in number as the Services continue to develop the capabilities necessary for the transformation to a fully networked military force. Requirements may also emerge and continue to evolve following the fielding of a NCO capability because new technology has the potential to change how warfighters work. Requirements evolution results in requirements engineering challenges associated with the acquisition and development of network-centric software systems. As such, an approach is needed to provide for consistency in elicitation, management and documentation of evolving requirements for technological capabilities supporting NCO. The purpose of this research is to address the problem of evolving requirements. The requirements engineering framework proposed by this thesis incorporates classification theory and requirements modeling principles, and is supported by the Extensible Markup Language (XML) family of technologies. Particular attention has been paid to the selection of non-proprietary, platform independent technology to ensure data can be exchanged between organizations. The framework demonstrates a means by which requirements can be classified and structured in a standardized format. The result is a set of requirements that is consistent in structure and content, and that can be easily shared among all stakeholders because it utilizes one standard, non-proprietary format. This approach captures evolving software requirements of fielded network-centric software systems for use in the development of future systems. / US Navy (USN) author.

We study the problem of updating XML views defined over XML documents. A view update is performed by finding the base updates over the underlying data sources that achieve the desired view update. If such base updates do not exist, the view update is said to be untranslatable and rejected. In SQL, determining whether a view update is translatable is performed using schema level analysis, where the view definition and the base schema are used. XML schemas are more complex than SQL schemas, and can specify recursive types and cardinality constraints. There are two kinds of view updates: single view element update, where the user requires for an update over a particular view element, and a set of view elements update, where the user requires for an update over all view elements that satisfy a given XPath over the view. Accordingly, we propose one solution for each kind of view update problems based on schema level analysis for determining whether an update over XML views is translatable and for finding the translation if one exists, while considering the features of XML schemas.

XML is a very versatile data format that has been used to represent many different kinds of data, including web pages, books, business and accounting data, programming interfaces, vector graphics, system logs, and games. In a short span of time, it has gained wide acceptance as the document and data standard on the web. As more and more XML data gets generated everyday, a lot of research focus has been on query languages for XML. The World-Wide Web Consortium (W3C) has chosen XQuery as the standard language for querying XML. From an end-user point of view, XQuery sacrifices usability for expressiveness. We introduce FoXQ, a visual language that enables end users to query XML. FoXQ brings a lot of the functionality of XQuery within the reach of the end users without getting them embroiled in the intricacies of XQuery syntax. The query interface is form-based and the query model is based on a document metaphor in which the users formulate queries by filling out forms. / Graduation date: 2004
