Mobile Web Overview

Mobile computing has been a major trend for the past a few years. I first did a talk to the ACM student chapter at GSU in 2014 which gave an overview of web site design and application development for mobile devices and discussed key issues of adapting to this change. Topics include choices of mobile application development and delivery, basic principles and best practices of mobile friendly web sites and web applications, and major tools and frameworks. The talk eventually led to a lecture in my several courses including mobile web development, mobile system overview, introduction to mobile development, etc.

The slides are hosted on Edocr

Business Intelligence and Analytics Overview

Business intelligence is a broad term to describe a set of methods, processes, architectures, applications, and technologies that transform raw data into meaningful and useful information to support business operation and growth (Cardin, 2007). It is used to enable more effective strategic, tactical, and operational insights and decision-making. BI systems combine data gathering, data storage, data integration, and knowledge management with analytical tools to present complex internal and competitive information to planners and decision makers (Negash, 2004). Traditionally it has evolved from executive information systems and management information systems to specifically focus on data driven decision making (Power, 2007).

With each new iteration, BI system’s capabilities increased as enterprises grew more sophisticated in their computational and analytical needs and as computer hardware and software matured (Negash, 2004). A complete BI enterprise system is able to cover the full spectrum of a BI process, including major components of data management and integration, analysis, presentation, delivery, and domain applications which involve all components.
