Data mining automates the detection of relevant patterns in a database, using defined approaches and algorithms to look into current and historical data that can then be analyzed to predict future trends.
Because Data mining tools predict future trends and behaviours by reading through databases for hidden patterns.
And it allow organizations to make proactive, knowledge-driven decisions and answer questions that were previously too time-consuming to resolve.
Lot of companies & organizations are purchase and use these tools which designed by existing software & hardware platforms. These data mining tools integrated into new products or they can build their own custom mining tools.
For an example feeding the output of a data mining exercise into another computer system, such as a neural network that include algorithms, is quite common and can give the mined data more value.
This is because that data mining tool gathers the data, while the neural network makes decisions based on the data collected.
There are different types of data mining tools are available in the marketplace & each tool with their own strengths and weaknesses.
Specially Internal auditors need to be aware of some different kinds of data mining tools available and recommend the purchase of a tool that matches the organization's current detective needs. Otherwise it’s a waste of money & sometimes it harms to the data security.
