Architecture and system design issues of contemporary Web-based Information Systems

The rapid changes of information technology led to the proliferation of Web-based Information Systems (WIS). There has been already some research on the general model for analysis and design of WIS. This paper attempts to define a comprehensive framework for integrating the various viewpoints of model for WIS. Several components that compose of a WIS as analyzing and designing element are investigated and described as modeling element and enabling tool for creating consistent and integrated system. The major modeling components are: the Web site, semi structured document, business processes, element of knowledge management, the enterprise and information architecture, and autonomous software components providing functional services. These elements are integrated into a unified framework exploiting partly the object-oriented paradigm and partly other approaches for information system modeling. The outlined WIS model incorporates the most recent approaches for various paradigms of traditional information systems analysis and the most modern different approaches of WIS. The research result would be useful both theoretically and practically as it could present a comprehensive model for WIS assisting our understanding of properties of WIS and supporting, at the same time, a framework for being able to formulate a practical development method for achievement of WIS by organizations making the most of Web.
