The soybeans are processes in North America, but majority of energy demand today is in Asia/Pacific. The CEO has hired you to understand what is the most efficient method of delivering the product to Asia. You need to decide whether to process all in North America and then ship to Asia/Pacific, or ship raw to Asia/Pacific and then process.
Right Answer:
To determine the most efficient method of delivering soybeans to Asia/Pacific, you should conduct a cost analysis comparing the expenses of processing in North America versus shipping raw soybeans for processing in Asia/Pacific. Consider factors such as transportation costs, processing costs, tariffs, and demand in the target market. If processing in North America and shipping is cheaper overall, choose that option; if shipping raw soybeans and processing in Asia/Pacific is more cost-effective, opt for that.
Ques:- A cable TV company from Canada, World View, had recently entered the US market in the northeast to expand its market share. World View saw this move as an opportunity to capture a large part of the US market (4MM consumers) in a market with very little competition. However, in the last couple of years, much to the surprise of management, World View has been unable to make a profit. You have been hired to figure out why and advise them on their next move?
Right Answer:
World View should analyze their pricing strategy, customer acquisition costs, and service offerings.

Conducting market research to understand customer needs and preferences, optimizing their pricing model, and improving service quality could help them become profitable. Additionally, exploring partnerships or bundling services might attract more customers.
Ques:- A major auto service chain has enjoyed healthy returns on its 30-store operation for the past 10 years. However, management feels that the chain needs to expand, as the current geographical areas in which they are based have become saturated. For the past couple of years, they have aggressively pursued a growth strategy, opening an additional 15 stores. However, it seems that this approach has had negative returns. For the first time in over a decade, the chain’s profits dropped into the negative zone. You were hired to figure out why.
Right Answer:

The negative returns could be due to several factors: oversaturation in new markets, inadequate market research leading to poor location choices, increased competition, higher operational costs, or a lack of brand recognition in the new areas. Additionally, the rapid expansion may have stretched resources thin, impacting service quality and customer satisfaction. A thorough analysis of each new location's performance, customer feedback, and market conditions is necessary to identify the specific issues.

Whatever you can do in TC you can do in DC and viceversa.
The main difference is that TC refers to the relation in
rows, but DC refers to the relation in columns.

Tuple calculus is destructive as apposed to domain calculus. This means that in Tuple Calculus if you manipulate the data in a table all the information that is not needed is destroyed. In domain calculus this is no the case.
