Q21.

What type of information can be derived from clickstream data?

Weather patterns

Customer preferences

Political affiliations

Historical events

Discuss

Answer: (b).Customer preferences Explanation:Clickstream data provides information such as the effectiveness of sales promotions, affinities between products, customer demographics, and general buying patterns.

Q22.

How does web technology contribute to information delivery?

It complicates the process

It limits access to information

It facilitates easy and continuous information delivery

It requires extensive training for users

Discuss

Answer: (c).It facilitates easy and continuous information delivery Explanation:Web technology facilitates easy and continuous information delivery, making it accessible around the clock.

Q23.

What is a benefit of connecting a data warehouse to the web?

Restricted access for internal users only

Limited scalability

Minimal training costs

Synchronization challenges in client/server environments

Discuss

Answer: (c).Minimal training costs Explanation:Connecting a data warehouse to the web leads to minimal training costs for users due to the use of web browsers.

Q24.

How does the web impact the growth of data warehouse usage?

Decreases user population

Limits access to a specific time of day

Facilitates supergrowth in usage

Reduces information delivery

Discuss

Answer: (c).Facilitates supergrowth in usage Explanation:The web facilitates "supergrowth" in data warehouse usage by providing universal access and an intuitive access mechanism, leading to challenges in scalability.

Q25.

What challenges does supergrowth pose for a web-enabled data warehouse?

Decrease in user population

Synchronization issues

Limited expansion in usage

Strain on scalability

Discuss

Answer: (d).Strain on scalability Explanation:Supergrowth poses a challenge for scalability, as the user base grows faster than the ability to scale up the web-enabled data warehouse to meet expanding usage requirements.

Q26.

How can the problem of supergrowth in a web-enabled data warehouse be anticipated and avoided?

By restricting access to internal users only

Opening the warehouse instantly to the public

Opening the warehouse in well-defined stages

Avoiding web enablement altogether

Discuss

Answer: (c).Opening the warehouse in well-defined stages Explanation:Anticipating and avoiding the problem of supergrowth involves opening the web-enabled data warehouse in well-defined stages, monitoring the growth pattern in usage.

Q27.

Why is it advisable to open the web-enabled data warehouse to internal users first?

To minimize the number of users

To contain enthusiasm and control growth

To restrict access to specific time slots

To limit information delivery

Discuss

Answer: (b).To contain enthusiasm and control growth Explanation:Opening the web-enabled data warehouse to internal users first helps in containing enthusiasm and controlling growth, allowing for monitoring the usage pattern.

Q28.

How can supergrowth be dealt with if opening the warehouse to all users is unavoidable?

By limiting access to specific time slots

By finding the point of leveling off in the growth curve

By restricting access to internal users only

By avoiding web enablement altogether

Discuss

Answer: (b).By finding the point of leveling off in the growth curve Explanation:Dealing with supergrowth involves finding the point up to which usage will grow and then level off, as shown in the growth curve.

Q29.

What characteristic of the growth curve is crucial in dealing with supergrowth?

Continuous increase in usage

Rapid acceleration of growth

Leveling off after the initial stages

Synchronization challenges

Discuss

Answer: (c).Leveling off after the initial stages Explanation:Supergrowth occurs in the initial stages, but the growth curve levels off after that, making it manageable.

Q30.

How can the number of users and the leveling-off point be determined for a web-enabled data warehouse?

Industry-standard charts

Trial and error

Estimation based on environment and circumstances

Fixed mathematical formulas

Discuss

Answer: (c).Estimation based on environment and circumstances Explanation:The number of users and the leveling-off point for a web-enabled data warehouse depend on the circumstances and conditions of the environment, requiring estimation techniques.
