This collection, entitled Breakthrough Discoveries in Information Technology Research: Advancing Trends , aims to inform researchers and practitioners of novel and emerging research in information science and technology, allowing for the discussion and dissemination of critical concepts that will promote further study and innovation....

This volume of Annals of Information Systems will acknowledge the twentieth anniversary of the founding of the International Society for Decision Support Systems (ISDSS) by documenting some of the current best practices in teaching and research and envisioning the next twenty years in the decision support systems field. The volume is intended...

Database design is the process of determining the organization of a database, including its structure, contents, and the applications to be run. For a long time, database design was considered a task for experts, and was regarded as more of an art than a science. However, much progress has been made in database design, and it is now...

Computer graphics is more than an isolated discipline at an intersection of computer science, mathematics, and engineering. It is the very visible leading edge of a revolution in how we use computers and automation to enhance our lives. It has changed forever the worlds of engineering and science, medicine, and the media, too. The wonderful...

On November 4, 2009, Alberto and I had dinner with many other Analysis Services experts from all around the world, including many people from the Microsoft development team. We were in Seattle for the PASS Summit 2009, a conference for SQL Server professionals, and because Redmond, Washington is very near to Seattle, events like this often...

Performance-aware Component-based Software-Development A characteristic of an engineering discipline is the ability to predict the impact of design decisions. For example, in civil engineering accurate predictions of the impact of adding an additional ?oor on a construction’s statics are available. Having a similar ability in software...

The origin of this volume came while planning the 2009 International Conference on Decision Support Systems. The theme of that 2-day conference was “Assessing Today and Envisioning Tomorrow.” We wanted to summarize where the field had been and generate ideas regarding where it was going. The meeting brought together...

Mr. Sorin A. Huss was born in Bukarest, Romania on May 21, 1950. He attended a secondary school with emphasis on mathematic and scientific topics in Dachau near Munich and after his Abitur...

Exploratory data analysis (EDA) was conceived at a time when computers were not widely used, and thus computational ability was rather limited. As computational sophistication has increased, EDA has become an even more powerful process for visualizing and summarizing data before making model assumptions to generate hypotheses, encompassing...

R is a high-level language and an environment for data analysis and graphics. The design of R was heavily influenced by two existing languages: Becker, Chambers and Wilks’ S and Sussman’s Scheme. The resulting language is very similar in appearance to S, but the underlying implementation and semantics are derived from Scheme. This...
