Semantics and Tools for Active Modeling and Processing in the Enterprise Data Environment (STAMPEDE)

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.
