Developing a natural language interface to complex data
Gary G. Hendrix, Earl D. Sacerdoti, Daniel Sagalowicz, Jonathan Slocum
Pages: 105-147
DOI: 10.1145/320251.320253
Aspects of an intelligent interface that provides natural language access to a large body of data distributed over a computer network are described. The overall system architecture is presented, showing how a user is buffered from the actual...

A note on associative processors for data management
Glen G. Langdon, Jr.
Pages: 148-158
DOI: 10.1145/320251.320254
Associative “logic-per-track” processors for data management are examined from a technological and engineering point of view. Architectural and design decisions are discussed. Some alternatives to the design of comparators, garbage...

Data file management in shift-register memories
Werner E. Kluge
Pages: 159-177
DOI: 10.1145/320251.320256
The paper proposes a shift-register memory, structured as a two-dimensional array of uniform shift-register loops which are linked by flow-steering switches, whose switch control scheme is tailored to perform with great efficiency data...

System level concurrency control for distributed database systems
Daniel J. Rosenkrantz, Richard E. Stearns, Philip M. Lewis, II
Pages: 178-198
DOI: 10.1145/320251.320260
A distributed database system is one in which the database is spread among several sites and application programs “move” from site to site to access and update the data they need. The concurrency control is that portion of the system...
