Data Mining 3 whom had made the same or similar purchases. Amazon has been successful at cross selling because it knows what to suggest to its customers” (Efraim Turban, Linda Volonino, 2011). Web mining can help a business provide more and better products to its customers. Analysts are able to combine information from web mining and Dta mining to make these discoveries. Web mining can also be used in the surveillance of competitors. Businesses can research their competitors’ progress and practices to see if there is anything that can be done differently. Data mining is based upon the history of the company. Information such as sales, fraudulent credit card use, machinery failures or classifying customer demographics are all derived from within the company. Therefore algorithms are fairly reliable because the data it uses is coming straight from the company not an outside source. Algorithms may not be accurate when analysts of one company are trying to compare the data of another company. Choosing the best algorithm to use for a specific analytical task can be a challenge. While you can use different algorithms to perform the same business task, each algorithm produces a different result, and some algorithms can produce more than one type of result. (Data Mining Algorithms (Analysis Services - Data Mining), 2012). Data Mining Algorithms can “also impose limitations when it is costly or impossible to scan large databases multiple times or access records at random” (Bradley, Paul, Gehrke, Johannes,Ramakrishnan, Raghu Srikant, Ramakrishnan, 2002). When it is difficult to collect all the facts needed a clear prediction cannot be made and that can be a problem for the future of a business.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
