THE CARNOT HETEROGENEOUS DATABASE PROJECT - IMPLEMENTED APPLICATIONS

The Carnot project was an ambitious research project in heterogeneous databases. It integrated a variety of techniques to address a wide ran ge of problems in achieving interoperation in heterogeneous environmen ts. Here we describe some of the major implemented applications of thi s project. These applications concern (a) accessing a legacy scientifi c database, (b) automating a workflow involving legacy systems, (c) cl eaning data, and (d) retrieving semantically appropriate information f rom structured databases in response to text queries. These applicatio ns support scientific decision support, business process management, d ata integrity enhancement, and analytical decision support, respective ly. They demonstrate Carnot's capabilities for (a) heterogeneous query processing, (b) relaxed transaction and workflow management, (c) know ledge discovery, and (d) heterogeneous resource model integration.
