Final answer:
Implementing the REA diagram into a relational database requires multiple tables, with each entity in the diagram corresponding to a separate table and relationships represented through foreign keys.
Step-by-step explanation:
Implementing the REA diagram into a relational database would require multiple tables.
The number of tables required depends on the complexity of the diagram and the relationships between entities.
Each entity in the REA diagram will usually correspond to a separate table in the relational database, and the relationships between entities will be represented through foreign keys.
For example, if the REA diagram includes entities for customers, products, and sales, you would typically have three tables: a table for customers, a table for products, and a table for sales, with relationships established through foreign keys.
