this research discusses the process of designing a conceptual model for a new information system, i.e. electronic document management system. the new system is designed for an educational institute (itvhe) whose managers are the research population. the research methodology is based on structured analysis and design methodology (ssadm). in the end, the new system proposed using a data flow diag...

It has been shown in Symanzik and Baker (1996a) that a particular subclass of Formalized Data Flow Diagrams (FDFD's) is Turing equivalent. We call this Turing equivalent subclass of FDFD's persistent flow-free Reduced Data Flow Diagrams (PFF--RDFD's). PFF--RDFD's do not contain persistent flows, reference only values whose types have finite domains, and have enabling conditions that contain no ...

System development life cycle (SDLC) is a process uses during the development of any system. SDLC consists of four main phases: analysis, design, implement and testing. During analysis phase, context diagram and data flow diagrams are used to produce the process model of a system. A consistency of the context diagram to lower-level data flow diagrams is very important in smoothing up developing...
