Explain the design steps of the transform mapping.
-  Review the fundamental model. 
 
-  Review and refine the DFD for the software. 
 
-  Verify whether the DFD has the transform or transaction mapping. 
 
-  Isolate the transform center by specifying incoming and outgoing flow boundaries. 
 
-  Perform first-level factoring. 
 
-  Perform second-level factoring. 
 
-  Refine the first iteration architecture using design heuristics for enhanced software quality.
