Establishing an Information Architecture Integration with an Open Systems Environment
(EDUCAUSE, 1992-01-01) Bernbom, Gerry; Cromwell, Dennis
This paper describes the conceptual basis for a structured data architecture, and its integration with the deployment of open systems technology. The key strategic initiatives which brought these efforts together are discussed: commitment to improved data access, migration to relational database technology, deployment of a high-speed, multi-protocol network, and orientation to workstation-centered computing. Details of Indiana University's data architecture are presented, focusing on the relationship of operational to information-detail databases, the creation of synthetic data structures and higher order "data collections," and the integration of the university-wide architecture with local and departmental data sources. Discussion of the underlying technology paradigm addresses the integration of proprietary components with "open" systems solutions in a strategy of technology coexistence that addresses: mainframe/server, workstation/client, networks, gateways, and database management systems. Finally, some next critical events are outlined for both the architected data environment and the open systems technology environment.
Foundations for Innovation: Information Technology at Indiana University
(Bloomington, Indiana : Indiana University, 2000) Adams, Karen; Aune, Kirk; Bernbon, Gerry; Boschmann, Erwin; Cromwell, Dennis; Donaldson, David; Dunn, Michael; Egolf, Michael; Elmore, Garland; Fitzpatrick, Christine; Halbrook, Michael; Holland, Norma; Jung, Diane; Mand, Larry; McRobbie, Michael; Moore, Greg; Pearson, Doug; Peebles, Christopher; Reynolds, Steve; Stephan, Bill; Steward, Don; Stewart, Craig; Voss, Brian; Waren, Marsha; Welty, Gordon; Wernet, Eric; Wernet, Julie; Williams, Jim
This booklet describes information technology (IT) on the campuses of Indiana University, principally the infrastructure and services, but also some of the main academic programs in this area. IT is fundamental to the future of teaching, learning, and research in modern American research universities and it is the foundation for innovation, on which America's continuing global leadership in higher education depends. IT is a transformational force of enormous power and potential for the whole of higher education, nationally and globally. In the pages that follow the wide-ranging scope and scale of IU' s uses and applications of IT are described. From this it will be clear that IT extends into nearly every part of the University and is a vital tool for academic leadership.
Security in a Client-Server Environment

Security in a Client-Server Environment
(1993-12-09) Bernbom, Gerry; Bruhn, Mark; Cromwell, Dennis
This paper describes the strategy adopted by Indiana University in the design and implementation of a security model for the client/server environment. The strategic initiatives which were the catalyst for this effort are presented: deployment of a high speed network, an orientation to workstation-centered computing, and a growing commitment to open-systems solutions. Details of the IU security architecture are discussed, focusing on the three components of security -- identification, authentication and authorization -- and why they are critical success factors to implementing a client/server information system. The paper identifies security problems of an open-systems and client-server environment, the technology components of a security solution, and the work done by Indiana University to supplement the immature technology in this area. The paper also makes a case for clear analysis of security exposures, and the importance evaluation security solutions in light of evolving industry standards.
Storage Briefing: Trends and IU
(2013-08) Floyd, Mike J.; Seiffert, Kurt; Stewart, Craig A.; Turner, George; Cromwell, Dennis; Hancock, Dave; Kallback-Rose, Kristy; Link, Matthew R.; Simms, Steve; Williams, Troy
Storage technology is in a period of accelerating change. Rapid developments in flash memory and cloud services are the most visible indicators. Uses of storage face growing regulatory and funding agency compliance, and a growing bundling between software systems and storage options. This briefing presents information on industry, regulatory, and usage trends at Indiana University (IU), and comparisons of storage services with Purdue and other Committee on Institutional Cooperation (CIC) schools. The sections of this document are largely independent of each other, so readers may focus on areas of interest.
