How can an REA diagram show that a team of employees is involved in performing an event—recognizing that the number of employees participating varies for different instances of the event (e.g., one row in the event table might be linked to 3 employees, another row linked to only 2 employees, and so on)?
A. By using foreign keys in the event entity
B. By linking the event to multiple different employee entities
C. By using primary keys in the event entity
D. By creating an M:N relationship between the employee and event entities
Two types of locations entities (Warehouses and Financial Institutions). What other location entities might be found in the REA diagrams for different types of companies? Why?
Explain why standard prices and costs are recorded in resource entities, but actual prices and costs are recorded in event entities.
