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.…

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…

Educational technologists may advance the state of the field by increasing capacity to develop software tools and instructional applications. Presently, few academic programs in educational technology require even a single computer programming course. Further, the educational technologists who develop software generally work independently or in…

This Management Information Systems Manual for the Illinois Community College Board (ICCB) provides basic information for submitting data to the ICCB. The manual is published every two years, and an addendum is published in the off years. It highlights and summarizes information from other documents, without being meant to replace those documents.…

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…

Describes research aimed at investigating dynamically evolving database environments and corresponding schemata that allow storage and manipulation of variable length data, a variable number of fields per record, variable length records and fields, and dynamically defined objects. Proposes a new framework for dynamic database environments.…

The ability of operating departments of an institution to mechanically gather, summarize, and report "local" data is discussed. Problems are outlined that arise when departments have the ability to produce data and do so with rigorous quality control by the institution's central information management organization. (MLW)

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,…

The entity-relationship (ER) approach to database design is defined, and a specific example of an ER model (personnel-payroll) is examined. The requirements for converting ER models into specific database management systems are discussed. (Author/MSE)

This report presents an objective overview of features of six selected data-base management systems and federal user experiences with these systems. Application criteria were developed in order to aid in the evaluation and selection of data-base management systems. The advantages of generalized data-base management systems over traditional methods…

Discusses what generalized data-based management systems are and how they can be utilized in the field of education. Advantages of using the system and its effect on educational management are considered in detail. (DN)

Prospective student data, supplied by various national college testing and student search services, can be matched with existing student records in a college admissions database. Instead of relying on one unique record identifier, such as the student's social security number, a technique has been developed that is based on a number of common data…

This paper proposes construction of a separate data base environment for university planning information, distinct from data bases and systems supporting operational functioning and management. The data base would receive some of its input from the management information systems (MIS)/transactional data bases and systems through a process of…
