In physical mining of minerals from the earth, miners use heavy machinery to break up rock formations, extract materials, and separate them from their surroundings. In data mining, the heavy machinery is a data warehouse —it helps to pull in raw data from sources and store it in a cleaned, standardized form, to facilitate analysis.

As its name metaphorically suggests, data mining is a process of carefully reviewing and processing large quantities of data (the “dirt”) to discover important patterns, findings or correlations (the “diamonds”) which might be important for the business.
Why is automation important in data mining?
In data mining too, automation is essential to speed up the process, and go deeper in the breadth of data to derive insights. Common uses of data mining include analysis and predictive modeling for marketing campaigns, pricing, fraud detection, financial forecasting, and analyzing website traffic.
What is the key type of automation used in data mining projects?
A key type of automation used in data mining projects is machine learning and natural language processing (NLP). These techniques make it possible to identify patterns and predict outcomes within large data sets.
What is engine in data science?
Engines that work on input data without a corresponding outcome (output variable), and can be used to model the underlying structure of the data set. There is no correct answer—the algorithm is tuned to derive meaningful structure from the data.
Why should data miners avoid spurious results?
Data miners should avoid spurious results that are not statistically or empirically valid. It is sometimes difficult to prove validity in data mining, but practitioners should aim to achieve the highest possible fit between model and analyzed data.
What is heavy machinery used for?
In physical mining of minerals from the earth, miners use heavy machinery to break up rock formations, extract materials, and separate them from their surroundings. In data mining, the heavy machinery is a data warehouse —it helps to pull in raw data from sources and store it in a cleaned, standardized form, to facilitate analysis.
What is data warehouse?
A Data Warehouse can be defined as a Database or a collection of Databases used to centralize an enterprise’s historical business data. These data sources could be the Databases of various Enterprise Resource Planning (ERP) systems, Customer Relationship Management (CRM) systems, and other forms of Online Transactional Processing (OLTP) systems. Data Warehouse is the most preferred form of data storage today due to its ability to scale storage requirements up or down as per the business and data requirements. This means that a Data Warehouse is capable of providing unlimited storage to any business.
What is data mining?
Data Mining can be defined as the process of analyzing large volumes of data to derive useful insights from it that can help businesses solve problems, seize new opportunities, and mitigate risks.
