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…

Networks, such as social networks, are a universal solution for modeling complex problems in real time, especially in the Big Data community. While previous studies have attempted to enhance network processing algorithms, none have paved a path for the development of a persistent storage system. The proposed solution, GraphStore, provides an…

Any librarian who has managed electronic resources has experienced the--for want of words--"joy" of gathering and analyzing usage statistics. Such statistics are important for evaluating the effectiveness of resources and for making important budgeting decisions. Unfortunately, the data are usually tedious to collect, inconsistently organized, of…

A study was conducted to propose a research-based model for a longitudinal data research system that addressed recommendations from a synthesis of literature related to: (1) needs reported by the U.S. Department of Education, (2) the twelve mandatory elements that define federally approved state longitudinal data systems (SLDS), (3) the…

Today many data warehousing systems are data rich, but information poor. Extracting useful information from an ocean of data to support administrative, policy, and instructional decisions becomes a major challenge to both database designers and measurement specialists. This paper focuses on the development of a data processing system that…

This discussion of the general principles of structure and construction of numeric databases introduces the concept of data points, their relationship to each other, and their storage in a nonredundant way. The collection of numeric data and their integration into the database structure are explained. Eight references are cited. (EJS)

Discusses an open-ended, generalized programing system which eliminates the duplication of effort and materials in data collection, storage, and reporting that is common in most piecemeal-evolved current management systems. (DE)

Applying to air quality data, procedures are presented for site characterization, method identification, data validation, and data summarization that are being established by the Environmental Protection Agency for the National Aerometric Data Bank. Topics review screening criteria, atypical results (data outliers), data accuracy and precision,…

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 data file user's manual documents the procedures used to collect and process high school transcripts for a large sample of the younger cohort (1980 sophomores) in the High School and Beyond survey. The manual provides the user with the technical assistance needed to use the computer file and also discusses the following: (1) sample design for…

One of four projects conducted by the American Statistical Association (ASA) in cooperation with the Bureau of the Census, the conference explored the most important and fruitful research and development topics within the user-oriented software domain. Its objectives were to (1) develop recommendations on mechanisms to improve access to and use of…

A look at how the Atlanta Public Schools has utilized computers for collecting data to support a large community of computer users and a variety of computer applications. (Author/HB)

This manual has been produced to familiarize data users with the procedures followed for data collection and processing of the first follow-up dropout component of the National Education Longitudinal Study of 1988 (NELS:88). Necessary documentation is also provided for use of the data files. The base-year population covered by the NELS:88 included…

This document describes the computerized procedures developed and utilized by Montgomery College (Maryland) to maintain records related to student academic progress. The new system was fully operable by fall 1972. Systems development included: (1) the conversion of past student records to a permanent grade history file; (2) the development of a…
