Explain in detail about Structural Modelling.
-  Structural model contains a detail refinement of ERD, data flow model and control flow model. 
 
-  Creating an ERD. 
 
-  Example: Safe Home Security System. 
 
-  Developing relations and cardinality/Modality. 
 
-  Creating a data flow model using the guidelines. 
 
-  Making a control flow model which describes the structural link of Processes Control flows Control stores. 
 
-  State automation 
 
-  Process activation table.
