What is Data Mining?

We are living in an information-rich, data-driven world. While it’s comforting to know there’s a plethora of readily available knowledge, the sheer volume creates challenges. The more information available, the longer it can find the useful insights you need.

That’s why today we’re discussing data mining. We’ll be exploring all aspects of data mining, including what it means, its stages, data mining techniques, the benefits it offers, data mining tools, and more. Let’s kick things off with a data mining definition, then tackle data mining concepts and techniques.

We will now begin by understanding what is data mining.

What is Data Mining?

Typically, when someone talks about “mining,” it involves people wearing helmets with lamps attached to them, digging underground for natural resources. And while it could be funny picturing guys in tunnels mining for batches of zeroes and ones, that doesn't exactly answer “what is data mining.”

Data mining is the process of analyzing enormous amounts of information and datasets, extracting (or “mining”) useful intelligence to help organizations solve problems, predict trends, mitigate risks, and find new opportunities. Data mining is like actual mining because, in both cases, the miners are sifting through mountains of material to find valuable resources and elements.

Data mining also includes establishing relationships and finding patterns, anomalies, and correlations to tackle issues, creating actionable information in the process. Data mining is a wide-ranging and varied process that includes many different components, some of which are even confused for data mining itself. For instance, statistics is a portion of the overall data mining process, as explained in this data mining vs. statistics article.

Additionally, both data mining and machine learning fall under the general heading of data science, and though they have some similarities, each process works with data in a different way. If you want to know more about their relationship, read up on data mining vs. machine learning.

Data mining is sometimes called Knowledge Discovery in Data, or KDD.

Now that we have learned what is data mining, we will now look at the data mining steps.

Data Mining Steps

When asking “what is data mining,” let’s break it down into the steps data scientists and analysts take when tackling a data mining project.

1. Understand Business 

What is the company’s current situation, the project’s objectives, and what defines success?

2. Understand the Data

Figure out what kind of data is needed to solve the issue, and then collect it from the proper sources.

3. Prepare the Data

Resolve data quality problems like duplicate, missing, or corrupted data, then prepare the data in a format suitable to resolve the business problem.
