Object comprehensions: A query notation for object-oriented databases,a predicate-based optimisable sub-language providing support for the class hierarchy; numerical quantifiers for dealing with occurrences of collection elements; operations addressing collection elements by position and order; a high-level support for interaction between different collection kinds; and recursive queries with computation.

Benchmarking parallel SQL database machines,on a large commercial database the benchmark system includes the specification of the test or “mimic” database and sets of transactions and queries, and the data/transaction generation tools. The benchmark uses synthetic data which closely resembles real world data and provides for evaluation of the scalability of system under test.

Conference proceedings 1994re organized in chapters on temporal databases, formal approaches, parallel databases, object-oriented databases, and distributed databases. In addition there are two invited presentations: "Managing open systems now that the "Glashouse" has gone" by R. Baker and "Knowledge reuse through networks of large KBs" by P.M.D. Gray.

A conceptual language for querying object oriented data,per demonstrates that with only modest extensions, such a schema definition language may serve as a query notation. These extensions are concerned solely with supporting the interactive nature of . querying, providing facilities for naming and displaying query operations and their results.

Stabilization and Privatization in Polandids unnecessary transaction blockings and restarts by executing alternative paths of transactions in parallel. Our approach uses additional hardware resources, mainly CPU — which would otherwise sit idle due to data contention — to improve transaction response time and throughput.
