This course examines various notions of information architecture, systems architecture, and organizational architecture, and their inter-relationships and interactions. Examples will be drawn from a wide variety of systems types, including traditional information systems, document management systems, workflow systems, groupware, Internet and intranet systems, enterprise systems, data warehousing, metadata repositories, and intelligent agents. Issues will include dealing with legacy and change, enterprise-wide interoperability and beyond (e.g., e-commerce), convergence of information content and processing, and support for knowledge management. Frameworks and techniques for architectural modeling, analysis, and design will be considered.
