What I learned from this lecture: We use Data Flow Diagrams to show the flow of data through different processses in software for example what happens when a user clicks a button DFD elements: - Data Store (data base) represented by two parallel lines - Process - represented by a circle - External entity - represented by a rectangle - Data flows - represented by arrows Rules of DFD: Data can flow from - External entity to process - Process to process - Process to Data Store Data cannot flow from - External entity to External entity - Data Store to data Store - External entity to data store
