Database Support for Very Large Hypertexts

by B. N. Rossiter, T. J. Sillitoe, M. A. Heather , 1990
"... this paper. In England, Parliament enacts statutes and Figure 1 shows related documents which have a bearing on the meaning of a particular section in an Act of Parliament. A section represents the smallest self-contained free-standing unit of text although subsections may be directly cited sometime ..."

. Their system is very flexible in the forms of data accepted but lacks a formal data model for controlling structures and for providing a general means of manipulating the data.

Database Model for Design Data

by Iztok Savnik, Tomaz Mohoric, Tomi Dolenc, Franc Novak - Proceedings of COMPEURO-93, IEEE , 1993
"... The paper presents a Construction Database Model (CDM) used for the conceptual level modelling of design objects. A primary intention of the CDM model is modelling hierarchically structured objects and construction dependencies among objects. CDM is an attribute based data model. The CDM model repr ..."

. They are described by means of a constructor, that can be compared to derived attributes as defined in [10, 4, 22, 8]. The constructor enables the description and reevaluation of the design object construction process. The CDM is used as a data model for the storage system Cons-Base, designed for storing data in CAD

Issues in the Design of EHTS: A Multiuser Hypertext System for Collaboration

by Uffe Kock Wiil - IN PROCEEDINGS OF HICSS-25 , 1992
"... This paper describes the architecture, issues from the design, and experiences from the use of EHTS (Emacs HyperText System), a multiuser hypertext system for collaboration. EHTS consists of a text editor, a graphical browser, and an active hypertext database named HyperBase. HyperBase is built on t ..."
Abstract - Cited by 26 (13 self) - Add to MetaCart
. Four categories of issues from the design and experiences from the use of EHTS are reported: architecture, collaboration, user interface, and data model. Based on our experiences with the client-server model, we suggest a new and improved architecture for the event driven multiuser hypertext system

Towards A Deductive Object-Oriented Database Language

by Serge Abiteboul - Data & Knowledge Engineering , 1990
"... A language for databases with sets, tuples, lists, object identity and structural inheritance is proposed. The core language is logic-based with a fixpoint semantics. Methods with overloading and methods evaluated externally providing extensibility of the language are considered. Other important iss ..."

in that success has been the existence of simple-to-use languages allowing the definition and manipulation of data. This has to be remembered while considering future generations of database systems. Object-oriented database systems are now being developed, e.g., [15, 12, 22, 39, 36]. An object-oriented approach

Materials for an exploratory theory of the network society.

"... ABSTRACT This article aims at proposing some elements for a grounded theor y of the network society. The network society is the social structure characteristic of the Information Age, as tentatively identi ed by empirical, cross-cultural investigation. It permeates most societies in the world, in v ..."

expressions of all kinds are increasingly enclosed in or shaped by this electronic hypertext. But the new media system is not characterized by one-way, undifferentiated messages through a limited number of channels that constituted the world of mass media. And it is not a global village. Media

A Unified Approach to Data Modeling for a Class of Image Database Applications

by Venkat N. Gudivada, Vijay V. Raghavan, Kanonkluk Vanapipat - in IEEE Transactions on Data and Knowledge Discovery , 1994
"... Recently, there has been widespread interest in various kinds of database management systems for managing information from images. Image Retrieval (IR) problem is concerned with retrieving images that are relevant to users' requests from a large collection of images, referred to as the image da ..."

introduced a unified framework for retrieval in image databases in [22]. Our approach to the image retrieval problem is based on the premise that it is possible to develop a data model and an associated retrieval model that can address the needs of a class of image retrieval applications. The key to domain

22 A Constraint Specification Approach to Building Flexible Workflows

are required to ensure that the work contained in the tasks which is carried out by the performer on the entity, is done correctly to ensure the integrity, reliability and consistency of the business process. Information systems in the business community are currently shifting from a data centric approach

"... Human Genome Project databases present a confluence of interesting database challenges: rapid schema and data evolution, complex data entry and constraint management, and the need to integrate multiple data sources and software systems which range over a wide variety of models and formats. While the ..."
