Abstract : This technical report briefly describes a six-phase methodology for designing an information system: formulation of the system outline, analysis of requirements, design of the global logical data base, definition of data base processes, design of the physical data base, and simulation of data base operations. The methodology is based on the extensive use of computer-aided design tools, including the Problem Statement Language/Problem Statement Analyzer (PSL/PSA). The development and application of the methodology to a very large design effort are described; numerous actual problems are described to demonstrate the need for the methodology. (Author)
