Semantics and Tools for Active Modeling and Processing in the Enterprise Data Environment (STAMPEDE) Navy SBIR FY2008.1 Sol No.: Navy SBIR FY2008.1 Topic No.: N08-101 Topic Title: Semantics and Tools for Active Modeling and Processing in the Enterprise Data Environment (STAMPEDE) Proposal No.: N081-101-0630 Firm: Stottler Henke Associates, Inc. 951 Mariner''''s Island Blvd., STE 360 San Mateo, California 94404 Contact: Eric Domeshek Phone: (617) 616-1291 Web Site: www.stottlerhenke.com Abstract: Databases are proven shared repositories for the enterprise, and conceptual modeling is solidly established as a valuable step in defining the contents of those databases. However, database contents, and the models that define them, are generally static, snapshot-oriented views of the world. While this may once have been the only feasible approach, advancing technology is relaxing memory hierarchy constraints, and now allows on-line integrated access to historical, hypothetical, and/or multi-perspective data. A well-defined and supported data model (e.g. with strong semantics, visualizations, editors and query tools) that explicitly encompassed change over time, space, perspective, and states-of-knowledge would enable more rapid development of new classes of applications. We propose to develop Semantics and Tools for Active Modeling and Processing in the Enterprise Data Environment (STAMPEDE). Our approach relies on an innovative combination of ideas and techniques from Aspect Oriented Programming, Meta Object Formalisms, and Generative Model Transformations. During Phase I we will flesh out the ideas underlying this approach and demonstrate their applicability in detail to a single active modeling aspect, including reflecting that aspect into the metamodel to enable active schema modeling. We will produce analysis and limited proof-of-concept tools, and develop a detailed Phase II design and work plan. Benefits: The results of this project will allow all kinds of enterprises to more fully and flexibly model their external environment and internal processes, taking advantage of advances in information technology to achiever deeper understanding and better responsiveness. All enterprises must deal with the reality of (1) data change over time, (2) variation and/or movement over space, (3) differences in organizational, functional, or personal perspectives, (4) information of unknown certainty or disparate provenance, and (5) schema change over time. STAMPEDE will enable unified modeling that consistently and coherently addresses all of these issues in a semantically well-founded framework. It will also provide mappings to underlying implementation and processing technologies to close the gap between conceptual and physical models. Return
