This paper presents an overview of EXODUS, an extensible database system project that is
addressing data management problems posed by a variety of challenging new applications …

We propose a novel formalism, called Frame Logic (abbr., F-logic), that accounts in a clean
and declarative fashion for most of the structural aspects of object-oriented and frame-based …

To investigate the interactions of extensibility and parallelism in database query processing,
we have developed a new dataflow query execution system called Volcano. The Volcano …

This paper attempts to define an object-oriented database system. It describes the main
features and characteristics that a system must have to qualify as an object-oriented …

Knowledge management entails the ability to store and enforce a collection of rules that are
part of the semantics of an application. Such rules describe integrity constraints about the …

Currently, POSTGRES is about 90 000 lines of code in C and is being used by as' sorted
“bold and brave” early users. The system has been constructed by a team of five part-time …

A temporal database contains time-varying data. In a real-time database transactions have
deadlines or timing constraints. In this paper we review the substantial research in these two …

In existing relational database systems, processing of group-by and computation of
aggregate functions are always postponed until all joins are performed. In this paper, we …

Due to the proliferation of database applications, the integration of existing databases into a
distributed or federated system is one of the major challenges in responding to enterprises' …

We demonstrate the power of object identities (oid's) as a database query language
primitive. We develop an object-based data model, whose structural part generalizes most of …
