What is the difference between entity relationship diagram and data flow diagram?
DFD basically describe the flow of data, means how data can be flow in a system where as ERD defines the relationship between entities. -> There is no such constrainst like cardinality,participation in dfd as compare to Erd.. ->In DFD, we show the storage of file using Parallel line where as ERD is just a conceptual represantation of data...
