Data mining is the process of using certain algorithms, software and tools to retrieve, collect, analyze and report information (known as predictive analysis) from a huge pool of data. Data mining is extremely useful these days where information is abundantly available. The information obtained by data mining is used for several applications for decision-making relating to direct marketing, e-commerce, customer relationship management, healthcare, oil and gas industry, scientific tests, genetics, telecommunications, financial services and utilities.

Web data mining is the process of automated extraction of data from the World Wide Web. The internet has extensive data about everything that can be used effectively for making intelligent decisions. However, retrieving as well as sifting through such huge databases is an arduous task. Hence, there are certain data mining tools that help to make this easier. The tools can pick out relevant data and interpret it as per requirements.

There are many kinds of Web data mining: standard mining, data verification and custom mining.
