The design of Postgres

by Michael Stonebraker, Lawrence A. Rowe - In Proceedings of the SIGMOD Conference , 1986
"... This paper presents the preliminary design of a new database management system, called POSTGRES, that is the successor to the INGRES relational database system. The main design goals of the new system are to: 1) provide better support for complex objects, 2) provide user extendibility for data types ..."

types, operators and access methods, 3) provide facilities for active databases (i.e., alerters and triggers) and inferencing including forward- and backward-chaining, 4) simplify the DBMS code for crash recovery, 5) produce a design that can take advantage of optical disks, workstations composed

The Object-Oriented Database System Manifesto

by Malcolm Atkinson, François Bancilhon, David DeWitt, Klaus Dittrich, David Maier, Stanley Zdonik , 1989
"... 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 objectoriented database system. We have separated these characteristics into three groups: ffl Mandatory, the ones the system must satisfy in ..."

query facility. ffl Optional, the ones that can be added to make the system better, but which are not mandatory. These are multiple inheritance, type checking and inferencing, distribution, design transactions and versions. ffl Open, the points where the designer can make a number of choices

ViST: A Dynamic Index Method for Querying XML Data by Tree Structures

by Haixun Wang, Sanghyun Park, Wei Fan, Philip S. Yu - In SIGMOD , 2003
"... much research has been done in providing flexible query facilities to extract data from structured XML documents. In this paper, we propose ViST, a novel index structure for searching XML documents. By representing both XML documents and XML queries in structure-encoded sequences, we show that query ..."

WSQ/DSQ: A Practical Approach for Combined Querying of Databases and the Web

by Roy Goldman, Jennifer Widom - In SIGMOD , 2000
"... We present WSQ/DSQ (pronounced "wisk-disk"), a new approach for combining the query facilities of traditional databases with existing search engines on the Web. WSQ, for Web-Supported (Database) Queries, leverages results from Web searches to enhance SQL queries over a relational databas ..."

A Query Facility for Common Intrusion Detection Framework

by Peng Ning, X. Sean Wang, Sushil Jajodia - In Proceedings of the 23rd National Information Systems Security Conference , 2000
"... It is essential for intrusion detection systems to share information in order to discover attacks involving multiple sites. Common Intrusion Detection Framework (CIDF) is an important step towards enabling different intrusion detection and response (IDR) components to interoperate with each other. A ..."
Abstract - Cited by 7 (2 self) - Add to MetaCart
. Although CIDF provides an infrastructure and language support that allows an IDR component to understand the information sent by another component, it does not contain a facility for a component to request specific information from other components. The lack of such a facility may result in a waste

Capturing and Querying Multiple Aspects of Semistructured Data

by Curtis E. Dyreson, Michael H. Böhlen, Christian S. Jensen - In Proceedings of the International Conference on Very Large Databases (VLDB ’98 , 1999
"... Motivated to a large extent by the substantial and growing prominence of the World-Wide Web and the potential benefits that may be obtained by applying database concepts and techniques to web data management, new data models and query languages have emerged that contend with web data. These mo ..."

Rationale for the Design of Persistence and Query Processing Facilities in the Database Programming Language O++

by R. Agrawal, N. H. Gehani , 1989
"... ODE is a database system and environment based on the object paradigm. It offers one integrated data model for both database and general purpose manipulation. The database is defined, queried, and manipulated in the database programming language O++, an extension of C++. O++ uses the C++ object defi ..."

Optimizing Object Queries Using an Effective Calculus
