System analysis involves defining users' goals and usage patterns, inventing functional solutions to meet those goals, defining navigation paths, creating UI mockups, and polishing interface elements. Data is raw material that is collected and processed into information, which is then used by managers to run organizations efficiently. The key characteristics of a system are organization, interaction, interdependence, and integration toward a central objective, while its core elements are inputs/outputs, a processor, control, feedback, boundaries/interfaces, and environment.

9. Data: Raw material
 Data collection costs money
 Collect only necessary and sufficient data
 Data is generally used by machines
 Data is useless unless it is processed to create INFORMATION
Information : Processed data
Data processed by machines giving information
Information is used to run an organization efficiently
Information used by managers to initiate actions
