Question
Imagine that you have been approached to discuss data mining in the customer order processing environment of a business. The purpose of the mining process, from the perspective of the business stakeholders, is to maximize customer services by expediting the production process.
Identify potential internal sources of data, including potential business operating systems that will provide source data, and describe a strategy for data source identification of the required data. Be sure to discuss the strengths and weaknesses of your approach.
What questions would you need to answer in order to provide more information or insight on their project?
In the data warehousing software, how are internal and external data sources differentiated?
Explanation / Answer
Ans.
The source of the data would be the database of the software that contains all the records of the customers. If new customer comes, then the database gets updated with a new entry. So, the operating system will have to process the entire data present in the file.
Limits: If the size of the file exceeds the memory limit, then the system would fail.
Strengths: File reading is faster. And if it is sorted by some key, then would be better for data manipulation.
