Answer to Question 1

Michael Porter includes five business activities in his definition of primary or operational activities. These include:
 Inbound logistics: receiving, storing and distributing product inputs.
 Manufacturing operations: transforming inputs into the final product.
 Outbound logistics: collecting, storing, and distributing the product to buyers.
 Sales and marketing: convincing customers to buy the product and selling it to them.
 Customer service: assisting the customers in their use of the product.

Answer to Question 2

The crow's foot E-R diagram notation uses a circle to indicate a minimum cardinality of zero (or optional) and a hash mark to indicate a minimum cardinality of one (or mandatory). Each symbol is placed on the relationship line just beyond the symbol indicating maximum cardinality.
