Locking performance in centralized databases
Y. C. Tay, Nathan Goodman, R. Suri
Pages: 415-462
DOI: 10.1145/4879.4880
An analytic model is used to study the performance of dynamic locking. The analysis uses only the steady-state average values of the variables. The solution to the model is given by a cubic, which has exactly one valid root for the range of...

Modeling the storage architectures of commercial database systems
D. S. Batory
Pages: 463-528
DOI: 10.1145/4879.5392
Modeling the storage structures of a DBMS is a prerequisite to understanding and optimizing database performance. Previously, such modeling was very difficult because the fundamental role of conceptual-to-internal mappings in DBMS...

Integrated concurrency control and recovery mechanisms: design and performance evaluation
Rakesh Agrawal, David J. Dewitt
Pages: 529-564
DOI: 10.1145/4879.4958
In spite of the wide variety of concurrency control and recovery mechanisms proposed during the past decade, the behavior and the performance of various concurrency control and recovery mechanisms remain largely not well understood. In addition,...

Language features for flexible handling of exceptions in information systems
Alexander Borgida
Pages: 565-603
DOI: 10.1145/4879.4995
An exception-handling facility suitable for languages used to implement database-intensive information systems is presented. Such a mechanism facilitates the development and maintenance of more flexible software systems by supporting the...
