Abstract. In a typical data migration project, analysts identify the mappings between source and target data models at a conceptual level using informal textual descriptions. An implementation team translates these mappings into programs that migrate the data. While doing so, the programmers have to understand how the conceptual models and business rules map to physical databases. We propose a modeling mechanism where we can specify conceptual models, physical models and mappings between them in a formal manner. We can also specify rules on conceptual models. From these models and mappings, we can automatically generate a program to migrate data from source to target. We can also generate a program to migrate data access queries from source to target. The overall approach results in a significant improvement in productivity and also a significant reduction in migration errors.
Integrated computational materials engineering (ICME) is a new approach to the design and development of materials, manufacturing processes and products. The approach proposes using a combination of modeling and simulation, datadriven reasoning and knowledge-guided decision making. Industrialization of this approach requires strong automation support. Modeling and simulation is a highly knowledge-intensive activity and integrated design requires knowledge cutting across several design domains. For the industrialization vision to succeed, it is essential to capture this knowledge and make it available in a usable form for people not so skilled in these areas. With this motivation, we are building a comprehensive computational platform to support this emerging design paradigm. We present an overview of the platform and discuss its knowledge engineering requirements. We present a knowledge modeling framework to address these requirements.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
