Discussion of XML focuses on indexing techniques for XML documents, grouping them into flat-file, semistructured, and structured indexing paradigms. Highlights include searching techniques, including full text search and multistage search; search result presentations; database and information retrieval system integration; XML query languages; and…

This paper describes a methodology for use in teaching an introductory Database Management System (DBMS) course. Students master basic database concepts through the use of a multiple component project implemented in both relational and associative data models. The associative data model is a new approach for designing multi-user, Web-enabled…

The current study replicates work of Regional Educational Laboratory (REL) Northeast and Islands. It describes dropout prevention programs in nine Mid-Atlantic Region (Delaware, the District of Columbia, Maryland, New Jersey, and Pennsylvania) school districts serving communities with populations of 24,742-107,250 (as of July 2008). All nine…

Feminist pedagogy as a research construct can be classified into gender and liberatory subgroups. Gender models frequently focus on learning. Liberatory models underline the social structures and power relations which constitute systems of oppression. Humor in practice may be used as a social corrective, or it may be used to extend power distances…

Presents a database system development model in which theoretical support in the form of automated theorem proving is brought to bear on the problem of enforcing integrity, i.e., ensuring that the database system represents only those states and transitions that are possible in the world it models. (MBR)

HIT methodology for conceptual data structure design is briefly described and exemplified. Main features of the methodology are the natural formalism of the description of conceptual schema, and an easy-to-understand graphical way of communication between both the designer and individual experts substituting future users. (Author/MBR)

A design method for information retrieval systems, based on a modelling technique, and derived from the general objectives and tasks set for the system is described. (12 references) (SJ)

Presents a new model for combining multiple sources of evidence in database merging based on logistic regression, and occurring only when ranks are available as a key to be used to merge different ranked lists obtained by various retrieval schemes. Results indicate better retrieval effectiveness than other approaches. (LRW)

The development of the conceptual "Functional Requirements for Bibliographic Records" (FRBR) Model enables records to be considered in terms of contextual relationships. Developments in software can capitalise on this to significantly improve the display of works through surfacing of these relationships. This paper reports on an investigation of…

This paper reports on a study aiming to develop a metadata model for e-learning coordination based on semantic web languages. A survey of e-learning modes are done initially in order to identify content such as phases, activities, data schema, rules and relations, etc. relevant for a coordination model. In this respect, the study looks into the…

Describes a lesson based on Taba's Inductive Thinking Model that offers a set of strategies to enhance the teaching of higher order thinking skills with the use of databases. Analyzing, synthesizing, and evaluating information are discussed, and strategies for guiding class discussion are presented. (eight references) (LRW)

A query language which is suitable for use with a relational data base system is discussed. The language is developed as an extension of ideas found in programming languages as well as relational calculus. The development is a step towards the integration of programming languages, query languages, and data base systems. The language offers a…

Three aspects of training and education for online searching of bibliographic and databases are addressed: (1) the present status--what is being taught, (2) a proposed model--what needs to be taught, and (3) the implementation of the model--who should teach what. The first section shows which organizations (library and information schools,…

Identifies requirements for representing structural aspects of nonconventional information system applications and demonstrates how recursive data models support information systems better than record-based database modelling tools. Structural concepts for representing office data objects are discussed and applied to an office example. Language…

Proposes a management-oriented model for describing and studying information behavior and details the testing of the resulting hypotheses through the use of a database describing the information-related attitudes and behaviors of 560 scientists and engineers. (FM)
