Although evaluation researchers frequently make use of focus groups and individual interviews as sources of qualitative data, there has been far less attention to dyadic interviews that create a conversation between two research participants. This article describes dyadic interviews as a format that shares many of the advantages of focus groups,…

The article introduces an application which supports the education of database systems, particularly the teaching of SQL and PL/SQL in Oracle Database Management System environment. The application has two parts, one is the database schema and its content, and the other is a C# application. The schema is to administrate and store the tasks and the…

Information-systems development continues to be a difficult process, particularly for virtual teams that do not have the luxury of meeting face-to-face. The research literature on this topic reinforces this point: the greater part of database systems development projects ends in failure. The use of virtual teams to complete projects further…

Enacted in 2014, the Workforce Innovation and Opportunity Act (WIOA) brought numerous changes to existing federal employment and training programs, including requiring the Department of Labor (DOL) and the Department of Education (Education) to implement a common performance accountability system across the six WIOA-designated core programs. WIOA…

Information Technology professionals and other knowledge workers rely on their ability to extract data from organizational databases to respond to business questions and support decision making. Structured query language (SQL) is the standard programming language for querying data in relational databases, and SQL skills are in high demand and are…

Graphs are widely used to model structures and relationships of objects in various scientific and commercial fields. Chemical molecules, proteins, malware system-call dependencies and three-dimensional mechanical parts are all modeled as graphs. In this dissertation, we propose to mine and index those graph data to enable fast and scalable search.…

This case consists of a business scenario of a small video rental store, Home Theater Video, which provides background information, a description of the functional business requirements, and sample data. The case provides sufficient information to design and develop a moderately complex database to assist Home Theater Video in solving their…

In this paper, we describe a Relational Algebra Query Language (RAQL) and Relational Algebra Query (RAQ) software product we have developed that allows database instructors to teach relational algebra through programming. Instead of defining query operations using mathematical notation (the approach commonly taken in database textbooks), students…

The launch of HealthCare.gov, the website of the Affordable Care Act (AKA Obamacare), was a major public relations disaster for the Obama administration. This case examines some of the factors that contributed to the failure of the launch and then details how Optum, an information technology service provider, considered the opportunity provided by…

In the context of association rule mining, the state-of-the-art in privacy preserving data mining provides solutions for categorical and Boolean association rules but not for quantitative association rules. This research fills this gap by describing a method based on discrete wavelet transform (DWT) to protect input data privacy while preserving…

This article details the spread and scope of large-scale 1:1 computing initiatives around the world. What follows is a review of the existing literature around 1:1 programs followed by a description of the large-scale 1:1 database. Main findings include: 1) the XO and the Classmate PC dominate large-scale 1:1 initiatives; 2) if professional…

In July 2013, the Early Childhood Data Collaborative (ECDC) surveyed 50 states and the District of Columbia to assess state early childhood data systems. The survey, completed by state education, health, and social services staff, focused on these three key aspects of state data systems, taken from ECDC's 10 Fundamentals: (1) Do states have the…

Although sustainability best practices for buildings are generally well understood, campuses face unique challenges because they are developed to support a diverse community with a variety of facilities. From academic facilities and labs to residences and sports facilities, all operate under one organizational umbrella. This can make it difficult…

This paper describes the use and benefits of Microsoft's Adventure Works (AW) database to teach advanced database skills in a hands-on, realistic environment. Database management and querying skills are a key element of a robust information systems curriculum, and active learning is an important way to develop these skills. To facilitate active…

The Internet and electronic commerce (e-commerce) generate lots of data. Data must be stored, organized, and managed. Database administrators, or DBAs, work with database software to find ways to do this. They identify user needs, set up computer databases, and test systems. They ensure that systems perform as they should and add people to the…
