15 Best Data Mining Tools of 2021

Data mining refers to the process of analyzing and exploring data sets in order to discover a meaningful pattern. Data mining tools are used in order to break down the data mining into six phases which includes business understanding, data understanding and preparation, modelling, evaluation and presentation. It symbolizes a sequence of events through the data mining process and serves as a guideline for a repetitive cycle rather than a linear process.

Data Mining Process

1. Understanding of the business

Firstly, users need to figure out the required situation and what they look to accomplish through data mining for your business. They need to define the problem, identify the business goals and then set up a plan to proceed.

2. Understanding of data

Users need to determine which type of data is required and then gather that data from all available sources.

3. Preparation of Data

It is a critical step in the data mining process where users can select, cleanse, construct and merge data thereby preparing it for analysis. While it may be time-consuming, data preparation can help you ensure the most accurate results by cleansing data and turning raw data into a solution which can actually work.

4. Modeling

It is the core of any machine learning project and lets the user decide which modelling technique to use to answer the project goals. It consists of analyzing data, generating tables and using plots & graphs in order to reveal patterns.

5. Evaluation of results

Users can evaluate the model results in light of the originally defined goals to make sure the model is accurate, complete and highlights what insights are valuable. Depending on the insights uncovered by data mining, it may help identify objective and additional questions required to answer.

6. Presentation of data

The final step is to turn all of the work into something which is useful to others. The Users will take the results in order to determine a proper deployment strategy which ensures the analysis is comprehensible. It can be as simple as creating a conclusive report or as complex as maintaining a data mining process from the beginning to end. It also includes delivering presentations to the customer and summarizes the project findings.

Data mining and Business intelligence

Business intelligence and Data mining are connected as data mining find the ‘what’ in the data while Business intelligence discovers the ‘why’ and ‘how’. Data mining finds the required information while BI determines why it is important.

Data mining helps make sense of the block of big data and provides answers to questions you weren’t looking for. With machine learning, data mining can accelerate the repetitive task of data analytics and modelling. It can help uncover the unknown pattern and abnormalities in data sets.

Companies can use data mining tools in order to identify the patterns and connections which can help to understand the customer and their business thereby leading to increasing revenue and reducing risk.

With applications in an array of industries which include fraud detection, customer relationship management and more, it can also lead to improved sales forecasting and can influence customer satisfaction. Besides this data mining tools can identify relevant information in data sets and turn data into actionable sights for decision making.
