Using the “Introduction to database design” process (Datanatic
Solutions BV. (nd.).) from the unit's referenced resources as your
guide, design a conceptual data model and logical
model for a petty cash system. Your models do not have to
be elaborate, just be sure to capture the core data, which you
think would be stored for a petty cash system.
Remember that conceptual and logical data models are created
mainly for business users and do not include lots of technical
details.
