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.
