Data mining cannot be performed until data warehousing is completed. This, commercial use of data mining. Data mining process involves using a large relational database to identify the correlation in certain data. The main role of the applications is to sift the data to identify correlations. A discussion on the acceptability of data mining. Data Mining - A Common Approach Although all data mining efforts are unique, they have a common set of process steps: • Infrastructure preparation - selection of hardware platform, database system, and one or more mining tools • Exploration - looking at summary data, sampling, and applying intuition, data visualization is useful here, ~ This language is an open-source tool used for graphical and statistical calculations.

The next section highlights the historical evolution of the database and directly discusses data warehouse and data mining information. A brief history of data warehousing and data mining is included. Furthermore, there are the problems faced in the early years in implementing the concept of data warehousing and data mining, where a data warehouse is separated from DBMS and stores a huge amount of data, which is usually collected from multiple heterogeneous sources such as files, DBMS , etc. The purpose is to produce statistical results. The key lessons from this definition are: • Data mining is a process of automated discovery of previously unknown patterns in large amounts of data. • This large amount of data is usually the historical data of an organization known as the data warehouse. • Data mining refers to large amounts of data, in gigabytes or abstract. A data warehouse is a repository for all data collected by an organization across various operational systems. be physical or logical. It is subject-oriented.
