Designing Information Systems focuses on the processes, methodologies, and approaches involved in designing information systems. The book first describes systems, management and control, and how to design information systems. Discussions focus on documents produced from the functional construction function, users, operators, analysts, programmers and others, process management and control, levels of management, open systems, design of management information systems, and business system description, partitioning, and leveling. The text then takes a look at functional specification and functional analysis, procedures and rules, and data modeling and data analysis. Concerns cover charting conventions and data modeling concepts, domains and domain integrity, deciding the most appropriate design solutions, and presentation of solutions to the user community. The manuscript examines implementation, user participation, aspects of human-computer interaction, project management, and system evaluation. Topics include appraisal of the simple approach, system evaluation with multiple purposes, data flows, data analysis and the data model, approaches to user involvement, and post-implementation evaluation and audit. The text is a valuable source of data for computer programmers and researchers wanting to explore how information systems are designed.
