INNOVATIVE  INFORMATION SYSTEMS  MODELLING TECHNIQUES  

Information Systems are the software and hardware systems that support dataintensive applications. One of the most critical stages of an Information System development cycle is the System Design stage. During this stage the architecture, components, modules, interfaces and system data are defined and modeled in order to fulfill the respective requirements that the developed Information System should meet. For accomplishing this task a number of requirement engineering methodologies have been proposed and presented in the respective literature aiming on the elicitation, analysis and modeling of the system requirements | INNOVATIVE INFORMATION SYSTEMS MODELLING TECHNIQUES Edited by Christos Kalloniatis INTECHOPEN.COM Innovative Information Systems Modelling Techniques Edited by Christos Kalloniatis Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2012 InTech All chapters are Open Access distributed under the Creative Commons Attribution 3.0 license which allows users to download copy and build upon published articles even for commercial purposes as long as the author and publisher are properly credited which ensures maximum dissemination and a wider impact of our publications.
