Introduction:

This article is giving brief of “Data Mining and Warehousing Solved Question Paper, Notes and Question Bank”.

We have included question papers from various universities so that one can have enough idea about field of data mining and warehousing.

Hope you will like this, if yes then please let us know in comments.

Collection of 100s of questions on wireless and mobile computing sort of question bank with some solved question papers and links to notes for study material.

Questions from different universities have been collated to give a comprehensive list of questions.

Important Questions on Data Mining and Data Warehousing:

Q. What is data mining?

Ans. So, data mining is discovery of patterns and information from possibly data sources using different statistical and computing techniques.

Q. What is the difference between data mining and data warehousing?

Ans. Data warehousing is the process of collating all the data from different sources into one common database, where data mining is the process of using various techniques to extract useful actionable information from data.

Q. Why data warehousing is important?

Ans. Data warehousing makes it possible to extract valuable information by joining various datasets for e.g.

• We can join marketing and sales data to understand which marketing campaign lead to most sales and has higher ROI,
• We can join website pages data with search data and understand what kind of search queries is driving traffic to my website.

Q. What are 3 types of data mining?

Ans. Different types of data mining are:

• Predictive Data Mining: Predictive data mining helps in finding what will happen next in the business gives certain conditions.
  • for e.g. What will be the sales next year or next quarter based on historical data.
    
• Prescriptive Data Mining: Prescriptive data mining is used to prescribe relevant steps to be taken for some process or business improvement.
  • For e.g. Spending more money on a particular sales campaign on Linkedin as it leads to more sales.
    
• Descriptive Data Mining: Descriptive data mining analyses data and tells what happens actually in business or product for e.g.
  • For e.g. North America customers are buying monthly plan, whereas Europe customers are more inclined towards semi-annual plans. -or- Traffic from North America on website decreases during thanks giving and during Christmas season.
