Tools and transformations—rigorous and otherwise—for practical database design
Arnon Rosenthal, David Reiner
Pages: 167-211
DOI: 10.1145/176567.176568
We describe the tools and theory of a comprehensive system for database design, and show how they work together to support multiple conceptual and logical design processes. The Database Design and Evaluation Workbench (DDEW) system uses a...

Automated resolution of semantic heterogeneity in multidatabases
M. W. Bright, A. R. Hurson, S. Pakzad
Pages: 212-253
DOI: 10.1145/176567.176569
A multidatabase system provides integrated access to heterogeneous, autonomous local databases in a distributed system. An important problem in current multidatabase systems is identification of semantically similar data in different local...

Using semantic values to facilitate interoperability among heterogeneous information systems
Edward Sciore, Michael Siegel, Arnon Rosenthal
Pages: 254-290
DOI: 10.1145/176567.176570
Large organizations need to exchange information among many separately developed systems. In order for this exchange to be useful, the individual systems must agree on the meaning of their exchanged data. That is, the organization must ensure...

Amalgamating knowledge bases
V. S. Subrahmanian
Pages: 291-331
DOI: 10.1145/176567.176571
The integration of knowledge for multiple sources is an important aspect of automated reasoning systems. When different knowledge bases are used to store knowledge provided by multiple sources, we are faced with the problem of integrating...

Index structures for selective dissemination of information under the Boolean model
Tak W. Yan, Héctor García-Molina
Pages: 332-364
DOI: 10.1145/176567.176573
The number, size, and user population of bibliographic and full-text document databases are rapidly growing. With a high document arrival rate, it becomes essential for users of such databases to have access to the very latest documents; yet the...
