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.…

Researchers are often distressed to discover that the data they wanted to use in their landmark study is not configured in a way that is usable by a Statistical Analysis Software Package (SASP). For example, the data needed may come from two or more sources and it may not be clear to the researcher how to get them combined into one analyzable…

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)…

Criteria to use in evaluating data processing efficiency, factors of file and record definitions, convenience of use for non-programmers, report generating capabilities, and customer support for generalized file management systems for use by the California junior colleges are indicated by the author. The purchase of such a system at the state…

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 learning activity packet (LAP) contains nine self-paced study lessons that allow students to proceed along a a 43-hour course of study for dBase III Plus at their own pace. The lessons are organized in the following way: objectives, completion standard, performance standard, a list of required materials, unit test, and exercises (applications…

This learning activity packet (LAP) contains five self-paced study lessons that allow students to proceed along a 22-hour course of study for dBase III Plus Advanced at their own pace. It continues the introductory dBase III Plus course. The lessons are organized in the following way: objectives, completion standard, performance standard, a list…

Discusses database structure, concepts, and management systems in library settings and describes the Comprehensive Automated Learning Resource System (CALS). This system was developed by NILRC to meet the needs of libraries which incorporate print and audiovisual materials in their collections. (RAA)

PMIS (Planning and Management Information System) is an information system that supports the decisionmaking process of executive management in local school districts. The system is designed around a comprehensive, longitudinal, and interrelated data base. It utilizes a powerful real-time, interactive data management system for strategic planning;…

The findings of a CAUSE survey of institutions of higher education that are either currently using or have used a database management system are presented. In addition to demographic information, other issues addressed are: management implications, systems concepts, systems development, personnel, operational considerations and prospects for the…

Based on existing literature and user experience, the systematic approach to data base evaluation presented here provides a method by which data processing administrators can optimize the probability of selecting the data base management system best suited for their institution. (Author/WM)

General Information Storage, Retrieval, and Application System (GENIRAS) is a computer-aided information system designed for the storage, retrieval, and manipulation of data files. The system gives the user (1) flexibility in defining and using data bases, (2) a wide range of procedures to be applied to the data, and (3) a variety of acceptable…

The accuracy and reliability aspects of data integrity are discussed, with an emphasis on the need for consistency in responsibility and authority. A variety of ways in which data integrity can be compromised are discussed. The following sources of data corruption are described, and the ease or difficulty of identification and suggested actions…

This publication describes an evaluation design developed to assess school-to-work (STW) efforts throughout the Saginaw Valley STW Partnership area in Michigan. An introduction is followed by an overview of the aim of evaluation. Section 3 describes how the variables pertinent to the evaluation of the STW program initiative were identified,…
