Enterprises search for ways on how it can generate useful information to this flood of information so it could help decision-makers. This is where data mining, a form of processing big volumes of raw data to search for less apparent relationships to trends, correlations or patterns, applies.
Why Data Mining is Important
More often than not organizations face a number of issues arising with the exponential growth of big data. The following reasons data mining is crucial for businesses:
- Gain Valuable Insights: Skilled in mining, raw data can focus on various levels of providing valuable insights that can vary from identifying new patterns to even predicting the customer’s action.
- Enhance Decision-Making: Decisions that are made out of data are highly credible and therefore deliver much more impactful results depending on the kind of field, say for example the operations, sales, and marketing field.
- Optimize Costs:Data mining reduces operating costs by identifying inefficiencies.
- Predict Future Outcomes: Major sectors can perform their activities more effectively by anticipating the upcoming events and plans through data mining.
What is Data Mining?
Data mining on the other hand is the process whereby you look for relationships within very large data sets. It involves the identification of past relationships between given sets of data to extract information that is not quite inherent.
Data mining on the other hand is the post-processing of data and more wired towards use and finding patterns.
Three main categories of data mining exist:
- Descriptive Data Mining:Often data is described using descriptive data mining techniques for better understanding of current trends.
- Predictive Data Mining: Predictive data mining is a methodology that describes information that is likely to occur in the future.
- Prescriptive Data Mining: Unlike descriptive and predictive data mining, prescriptive data mining makes recommendations for action.
Among the often used data mining techniques are:
- Clustering: Gathering similar information.
- Classification: Categorizing information into some predetermined categories.
- Regression: Regression is the act of predicting continuous variable values.
Advancements in Data Mining Techniques
Over the years, data mining techniques have advanced significantly, moving from basic statistical methods to complex machine learning models.The methods of machine learning that include clustering, classification and regression were actually developed for science but business and marketing also make its use. For example, clustering previously helped to categorise goods and services while categorization helped companies to sort through a huge amount of information by sorting information into predetermined categories. These are still being ongoing and can impact the state of data mining today, empower organisations to make better decisions and manage their businesses using data.
History of Data Mining
Data mining is a relatively recent concept which begins with the researchers’ experimenting on data collection and management at the early 1960s. But full realization of data mining as it is even today began only in the late 1980s and early 1990s. Data mining graduated from the simple data analysis forms as more complex algorithms and database management systems were created. Data mining originally was applied by marketing and finance for plain customer information view, while with the growth of computation tools, the involvement of data mining into the activity of numerous other businesses emerging. Data mining has become mandatory for most industries present in the market map the present and the future trends in the field with relatively higher accuracy.
The Data Mining Process
Aiming to refine data into insightful knowledge, data mining entails the following crucial steps:
- Understanding the Business Problem: Understanding the business problem ensures data mining focuses on well-defined questions.
- Data Collection and Selection: Subsequent to the identification of the goal, the necessary data is retrieved from outside records, databases, and warehouses.
- Data Cleaning and Preparation: It refers to sorting of missing data, removal of duplicate data, and preparation of data so that they can be of use.
- Data analysis and model building: To discover patterns and trends within the data, a number of models and methods include clustering or classification.
- Evaluating and Interpreting Results: The conclusions are evaluated on the criteria of whether or not they help meet the company’s goals. They also ask whether the patterns will be helpful? Do they answer the initial question?
- Deployment and Monitoring: Finally, the finding is applied; the resulting outputs are closely monitored as to its pervasive applicability and relevance.
How Data Mining Helps Businesses
Data mining has various useful conditions for a range of industries.
- Identifying Trends and Patterns:For instance, using data mining, the retailers can understand how customers are likely to behave in their stores, and they can consequently design effective marketing campaigns.
- Enhancing Customer Relationships: Data analysis to identify trends or behavior patterns will enable companies develop promotion strategies that will reduce attrition and increase corporate loyalty.
- Increasing Operational Efficiency: On choosing data mining one gets to discover that it will reveal bottlenecks in supply chains whereby organizations can trim down costs as well as increase efficiency.
- Use Cases Across Industries: In the healthcare sector data mining enables the assessment of health risk factors for a certain disease while in the financial sector by evaluating transactions for signs of irregularities data mining is used to detect fraud.
Ethics and Principles of Data Mining
Despite the fact that data mining could be highly beneficial, the management of ethical issues associated with it serve as a weak point of the companies interacting with such technologies.
