Data mining is a computational technology that contributes towards discovering knowledge through patterns in large volumes of data. It uses methods like artificial intelligence, machine learning, statistics, and database systems to extract information from a data set and transform it into an understandable structure for later use. The applicability of data mining has increased now and more and more businesses are using data mining in their functional processes. The article talks about the crucial components and concepts of data mining and data mining applications in the real world.

The crucial components of data mining that contribute towards improving data applicability, include –

Preprocessing – The first step in data mining is creating a data set. Data is usually sourced from a data warehouse. You need to preprocess the sourced data set to analyze them accurately.

Data Integration – The data you want to work with must be located in different formats such as Excel sheets, docs, images, etc., under different locations in your system. The data integration stage allows you to consolidate the different types of data and move them into a single source without affecting the reliability of the data.

Data Cleansing and Preparation – The target data set needs to be cleaned first and any type of data noise should be removed. They should be checked for any missing values, fix any structural errors, filter out the unwanted outliers, and remove duplicates.
