A data-flow diagram that represents a system's major processes, data flows, and data stores at a high level of detail refers to a: The process of discovering discrepancies between two or more sets of data-flow diagrams or discrepancies within a single DFD is referred to as:

The Haber Process is a good example of the use of equilibrium principles. The equation for the reversible reaction is : N2(g) + 3H2(g) <--> 2NH3(g) + 92 kJ Because raising the temperature will increase the speed of both the forward and reverse reactions, a high temperature should bring the reaction to equilibrium rapidly.

When the data flow in and out of a parent process do not match the data flow in or out of a child diagram, it is called: The process of creating a simple data flow diagram fragment for each unique system trigger is called: A method that provides conceptional freedom for representing processes and flows in a business system is the _____.
