Course overview

requirements of information for various functions - qualities of information - small case study - Systems Analysis and Design Life Cycle: Requirements determination - requirements specifications - feasibility analysis - final specifications - hardware and software study - system design - system implementation - system evaluation - system modification. Role of systems analyst - attributes of a systems analyst - tools used in system analysis - Information gathering - strategies - methods - case study - documenting study - system requirements specification - from narratives of requirements to classification of requirements as strategic, tactical, operational and statutory. Example case study - Feasibility analysis - deciding project goals - examining alternative solutions - cost - benefit analysis - quantifications of costs and benefits - payback period - system proposal preparation for managements - parts and documentation of a proposal - tools for prototype creation - Tools for systems analysts data flow diagrams case study for use of DFD, good conventions - leveling of DFDs - leveling rules - logical and physical DFDs software tools to create DFDs - Structured systems analysis and design - procedure specifications in structured English - examples and cases - decision tables for complex logical specifications - specification oriented design vs procedure oriented design - Data oriented systems design - entity relationship model - E-R diagrams - relationships cardinality and participation - normalizing relations - various normal forms and their need - some examples of relational data base design
