Detailed explanation-1: -Data mining, also called knowledge discovery in database (KDD), is the nontrivial extraction of implicit, previously unknown, and potentially useful information from data in database.
Detailed explanation-2: -Data Mining is a process of separating the data to identify a particular pattern, trends, and helpful information to make a fruitful decision from a large collection of data. It is also known by the name Knowledge Discovery in Database.
Detailed explanation-3: -Data mining is the extraction of implicit, previously unknown, and potentially useful information from data. It is applied in a wide range of domains and its techniques have become fundamental for several applications.
Detailed explanation-4: -Data discovery involves the collection and evaluation of data from various sources and is often used to understand trends and patterns in the data. It requires a progression of steps that organizations can use as a framework to understand their data.
Detailed explanation-5: -Knowledge Discovery Process: Data pre-processing for data mining including data cleaning selection efficient sampling and data reduction methods; evaluating consolidating and explaining discovered knowledge; data and knowledge visualization; interactive data exploration and discovery.
