The reality is that digital archives are fragile. Many people appreciate how information technology has revolutionized their lives but have spent little time reflecting on the historical significance of the migration from a print-based to a digital society. In the 100th year of the National Council for the Social Studies (NCSS), it seems timely to…

Massive amount of data is generated everyday through sensors, Internet transactions, social networks, video, and all other digital sources available. Many organizations store this data to enable breakthrough discoveries and innovation in science, engineering, medicine, and commerce. Such massive scale of data poses new research problems called big…

The study of this dissertation provides a solution to a very specific problem instance in the area of data mining, data warehousing, and service-oriented architecture in publishing and newspaper industries. The research question focuses on the integration of data mining and data warehousing. The research problem focuses on the development of…

Identifying academic misdemeanours and actual applied effort in student assessments involving practical work can be problematic. For instance, it can be difficult to assess the actual effort that a student applied, the sequence and method applied, and whether there was any form of collusion or collaboration. In this paper we propose a system of…

An unprecedented amount of information encompassing almost every facet of human activities across the world is generated daily in the form of zeros and ones, and that is often the only form in which such information is recorded. A good fraction of this information needs to be preserved for periods of time ranging from a few years to centuries.…

Defines a hash coding model for non-unique search keys and derives the expected number of accesses needed to retrieve all desired records from a computer storage device. (Author)

GENERAL CONSIDERATIONS INVOLVED IN THE DESIGN OF FILE ORGANIZATIONS FOR INFORMATION RETRIEVAL SYSTEMS ARE DISCUSSED. THE QUESTION OF INVERTED FILE AND SERIAL FILE SEARCHING ON MAGNETIC TAPE IS REVIEWED. BASED ON FORMULAS CONCERNING INDEX TERM USAGE, IT IS SHOWN FOR A SPECIFIC COLLECTION THAT SEARCHING THE SERIAL FILE IS MORE EFFICIENT THAN…

Examines design functions of present file organizations in the context of available data storage devices and identifies current developmental trends. (Author/RAA)

This report outlines a generalized storage scheme for large files of highly structured data, or catalogs, and describes their realization on magnetic tape. Each datum, large or small, is assigned to one of a number of data classes of which a user may define any number. The over-all organization of a catalog is given by a map that imposes a tree…

Describes the general methodology of time and motion studies and reports the results of a study which used this methodology to compare digitization of images in a microcomputer environment with storage of images on microforms. (CLB)

Discusses software developed to organize and retrieve electronically stored data, examining structure of the databases in which information is stored and the physical structure of the storage medium. Hierarchical and relational databases, unordered files, B-trees, and storage/software for specific purposes (such as weather, stock market, and…

Describes a dialog-program which uses basic statements available on a WANG 2200T version connected to a floppy-diskette to cross-reference a given set of keywords, author names, journal names, and specified reference numbers. Special program features are described and two references are listed. (Author/RBF)

Discusses digital imaging technology and examines document database conversion considerations. Two types of document imaging systems are described: (1) a work in process system, and (2) a storage and retrieval system. Conversion methodology is outlined, and a document conversion scenario is presented as a practical guide to conversion. (LRW)

Fourth installment of a directory published in four parts in "Database" (June and August) and "Online" (July and September) provides descriptions of 12 laserdisk products together with information on the producer, compatibility, type of laserdisk, search and retrieval software, interface with magnetic media, conditions of usage, price, and status.…

Investigates applicability of inverted file processing in magnetic bubble memories by presenting four magnetic bubble memory models as storage mediums: one based on a major-minor loop configuration; one utilizing a decoder design on a magnetic bubble memory chip; and two based on different structural configurations of the first two.
