Since you have previous knowledge of the ABC Sales System, you have been hired to present a solution to integrate the Human Resources functioning unit into the current system. You have been asked to develop a fully functional logical model (ERD) for the ABC Sales that includes entities of the Human Resources. You have to identify entities that can be used to develop the physical model of the system. Task: Not all entity requirements are determined at this point, therefore ABC SALES is looking for your expertise in assisting them with the design. You must research and come up with a possible solution for ABC Sales database team. It is important to look at the different areas to be considered in the design and based on your research and knowledge to make reasonable assumptions regarding each area. You will have to make assumptions in determining the entities, attributes/columns, the datatypes, relationships, primary/foreign key constraints, and cardinality. Your Entity Relationship Diagram (ERD) has to follow the rules of Normalization and adhere to 3rd Norm Form in your design
