SYSTEM ANALYSIS AND DESIGN Module 1: Data and Information (3) Types of information: operational, tactical, strategic and statutory – why do we need information systems – management structure – requirements of information at different levels of management – functional allocation of management – requirements of information for various functions – qualities of information – small case study. Module 2: Systems Analysis and Design Life Cycle (3) 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 Module 3: Information gathering (3) 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 Module 4: Feasibility analysis (3) 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 Module 5: Tools for systems analysts (3) 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 Module 6: Structured systems analysis and design (3) Procedure specifications in structured English – examples and cases – decision tables for complex logical specifications – specification oriented design vs procedure oriented design Module 7: Data oriented systems design (3) 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. Module 8: Data input methods (3) Coding techniques – requirements of coding schemes – error detection of codes – validating input data – input data controls interactive data input Module 9: Designing outputs (2) Output devices – designing output reports – screen design – graphical user interfaces – interactive I/O on terminals.
