Advances in Database Technology

It caught me by surprise that the relational data model, not long ago considered the most advanced, was referred to as a "conventional" model in a recently published database book.What is superseding it, if anything?What are the new database technologies that should be integrated in our database curricula?This tutorial will present an overview of a number of newer database technologies, including object data management, extended relational data model, data warehousing, on-line analytical processing, data visualization, etc., with references to important sources for further study.It will also identify concepts and technologies that are particularly relevant for graduates of IS programs and should thus be integrated into the curricula.Technological change, facilitated with the continuous advancements in information technology, is mainly driven by two forces.Database technology is responding to changes in (1) the amount and (2) the format of data stored and manipulated in the industry.Business databases that used to occupy only so many megabytes are now measured in giga-, tera-, or even peta-bytes.At the same time, the use of IT is spreading into new business and technical areas with different database needs from those of traditional computing.These new applications include computer-aided design, computer-aided manufacturing, computer-aided software engineering, text and hypertext, multimedia, office automation, Web and various other applications with complex data formats including knowledge bases.
