Data Flow Diagrams & Structured Analysis for Systems
Anah Objective Structured Analysis
Consider a system, fully or partially, so you can know all the tasks that are performed as part of daily activities, the information flows between them and how the data are stored to support management of them.
Purpose and scope
Its purpose is to support understanding of large complex systems through:
- Modeling components and constructing a model of the system
- Structured analysis components, including graphic symbols, data dictionary, descriptions of processes and procedures, and rules
- Data Flow Diagrams: a technique representing information flows and transformations that are applied to the data when moving from input to output of a system under study
What the technique allows
This technique allows:
- Analysis of a system
