Exploratory data analysis (EDA), data visualization, and visual analytics are essential for understanding and analyzing complex datasets. In this project, we explored these techniques and their applications in data analytics. The case discusses Tableau, a powerful data visualization tool, and Google BigQuery, a cloud-based data warehouse that…

The National Institute of Mental Health created the National Database for Autism Research (NDAR) to accelerate autism knowledge through data sharing and collaboration. However, our experience using NDAR reveals systematic challenges across several aspects of data submission, selection, management, and analysis that limit utility of this resource.…

Data is a powerful tool for the healthcare industry to use for managing, analyzing, and reporting on critical events in the field. The analysis of broad, salient data files aids healthcare businesses in uncovering hidden patterns, market trends, and customer preferences; these details may then be used to improve the quality and delivery of care to…

With the dramatic growth of text information, there is an increasing need for powerful text mining systems that can automatically discover useful knowledge from text. Text is generally associated with all kinds of contextual information. Those contexts can be explicit, such as the time and the location where a blog article is written, and the…

This paper addresses the problem of data management techniques for efficiently retrieving requested subsets of large data sets from mass storage devices. Describes the development of algorithms and software that facilitate the partitioning of a large data set into multiple "clusters" that reflect their expected access. (Author/JKP)

This manual is designed to assist librarians in programming unique database applications that meet specific library needs. Chapter 1 goes over the basic functions of working with Windows, describes terms such as multitasking, and shows how to use the menu and tool bars. Chapter 2 covers the basics, defines some useful terms, and presents the steps…

Discusses the 1995 OCLC/NCSA Metadata Workshop that met to define a standard set of data elements for describing network-accessible information resources. These document data elements had to be simple enough for authors and publishers to use, to facilitate discovery and retrieval, and to be useful as a basis for descriptive cataloging. (JKP)

This manual on microcomputer-based database management programs provides a description of the key characteristics of database software as well as guidelines for designing a database, uses of database programs, and selecting the right software. Three sets of concepts related to database management are listed and explained: creating a database,…

This report presents the rationale, motivation, and formal description underlying the General Retrieval and Information Processor for Humanities Oriented Studies (GRIPHOS) Management Information System. This system was devised to handle "card catalog" types of information; perform searches that are usually carried out in archives,…

INDEX, an interactive retrieval program developed at Pepperdine University, is described. It is easy to use and maintain, locates sources of information from a general description of the information needed, requires only a modest investment of time, and is widely applicable. (MLW)

Discusses information systems in which information use becomes the prime design factor rather than technology and content. Highlighted topics include the change of useless data to productive knowledge, a value-added process; environments in which problems requiring information exist; and users' perceptions of the benefits and costs of using…

Clemson University has developed techniques and procedures to assist in the construction and maintenance of administrative systems. Procedures as well as the tools and techniques used by all systems are discussed: online report request software, online user table maintenance software, report supervisor and report writer software, etc. (Author/MLW)

A subset of data base management techniques for the hardware/software functions necessary to support a management information system are discussed. Seven basic dimensions of data base design are: (1) data base life span, (2) logical record growth, (3) record content growth, (4) data set organization, (5) linkages, (6) design criteria and (7)…

The trend to distributed processing is being fueled by numerous forces, including advances in technology, corporate downsizing, increasing user sophistication, and acquisitions and mergers. Increasingly, the trend in corporate information systems (IS) departments is toward sharing resources over a network of multiple types of processors, operating…

An online data retrieval system for administrators of departments at Ball State University is described. The underlying concept is to pull together data elements from operational databases available on the mainframe and to make this information accessible to administrators through a straightforward retrieval system.
