12 Applications of Data Mining title banner

Data is a collection of discrete objective facts about an event or a process that, unless transformed into information, are of limited utility. 


We've been gathering a variety of information, ranging from simple numerical measures and text documents to more sophisticated information including geographical data, multimedia channels, and hypertext texts. 


What is Data Mining?


The technique of collecting useful information from a huge amount of data is known as data mining. It assists in the exploration and identification of important trends and patterns in datasets. 


Data mining is an interdisciplinary field that employs statistics, database systems, artificial intelligence, and machine learning techniques. Algorithms are used in data mining to extract patterns from databases.


Today, companies with a strong consumer focus — retail, financial, communication, and marketing organizations — use data mining to “drill down” into transactional data to determine pricing, customer preferences, and product positioning, as well as their impact on sales, customer satisfaction, and corporate profits. 


A shop can utilize data mining to design items and promotions that appeal to certain consumer categories based on point-of-sale records of customer purchases.

Large amounts of data are being collected nowadays. Every year, the amount of data gathered is said to nearly double. Data mining techniques are used to extract data or seek information from this enormous data. 


Data mining is utilized nearly anywhere there is a lot of data to store and analyze. Banks, for example, frequently employ ‘data mining' to identify potential clients who could be interested in credit cards, personal loans, or insurance. 


Because banks have transaction records and extensive profiles on their clients, they analyze this data and look for trends that might help them anticipate which consumers would be interested in personal loans or other financial products.


Whether commercial or scientific, the goal of data mining is the same: to uncover relevant information in order to improve decision-making or get a better knowledge of the world around us.
