Data mining , knowledge discovery, or predictive analysis – all of these terms mean one and the same. Broken down into simpler words, these terms refer to a set of techniques for discovering patterns in a large dataset.
Data cleaning and preparation. Data cleaning and preparation is a vital part of the data mining process. Tracking patterns. Tracking patterns is a fundamental data mining technique. Classification . Association . Outlier detection. Clustering . Regression . Prediction.
Data mining is a process of discovering patterns in large data sets involving methods at the intersection of machine learning, statistics, and database systems. Data mining is the analysis step of the “knowledge discovery in databases” process, or KDD.
Another example of Data Mining and Business Intelligence comes from the retail sector. Retailers segment customers into ‘Recency, Frequency, Monetary’ (RFM) groups and target marketing and promotions to those different groups.
Data mining has several types, including pictorial data mining, text mining, social media mining, web mining, and audio and video mining amongst others. Read: Data Mining vs Machine Learning.

Data Mining is primarily used today by companies with a strong consumer focus — retail, financial, communication, and marketing organizations, to “drill down” into their transactional data and determine pricing, customer preferences and product positioning, impact on sales, customer satisfaction and corporate profits.
Definition: In simple words , data mining is defined as a process used to extract usable data from a larger set of any raw data . It implies analysing data patterns in large batches of data using one or more software. Data mining is also known as Knowledge Discovery in Data (KDD).
For businesses, data mining is used to discover patterns and relationships in the data in order to help make better business decisions. Data mining can help spot sales trends, develop smarter marketing campaigns, and accurately predict customer loyalty.
Data Mining in Banking Banks use data mining to better understand market risks. It is most often used in banking to determine the likelihood of a loan being repaid by the borrower. It is also used commonly to detect financial fraud.
Skills needed to become a Data Mining Specialist Familiarity with data analysis tools, especially SQL, NoSQL, SAS, and Hadoop. Strength with the programming languages of Java, Python , and Perl. Experience with operating systems, especially LINUX.
Big data might be big business, but overzealous data mining can seriously destroy your brand. As companies become experts at slicing and dicing data to reveal details as personal as mortgage defaults and heart attack risks, the threat of egregious privacy violations grows.
