b) How would you cross-check that a dataflow diagram and entity life history diagram for a system are consistent with each other?

c) How would you cross-check that an entity relationship diagram and entity life history diagram for a system are consistent with each other?

d) Consider the Mod22 method (see Appendix at the end of the paper):
i) Identify and evaluate which approach to prototyping is used in the Mod22 method.
ii) Discuss the approach to systems development (i.e. software development process model) upon which the Mod22 method is based.
