What are the limitations of Structured approach (Data Flow) for systems development?
Solution
In system development structured approach and its allied technique, structured design, are
methods for analyzing business requirements and developing specifications for converting
practices into computer programs, hardware configurations, and related manual procedures.
Limitations of using data flow diagrams in system analysis and design include the following:
It is difficult to determine the processes (graph nodes) appropriately
It is difficult to partition the graph nodes in a meaningful and mutually agreed upon manner,
The size of the documentation needed to understand the Data Flow Graphs is large.
The DFDs are strongly functional in nature and thus subject to frequent change
Although data flow is emphasized in DFDs, data modeling is not.
In addition to it is hard for the customer to follow how the system concepts are mapped into data
flow graph nodes, it has also been very hard for the designers to implement these graphs.
Details of input/output are weakly displayed.
DFDs do not represent time.
