Data Mining what is? Tools, data mining breakthrough for business

In the era of data, referred to as the “new gold” of the business, not just resources, but also is a key factor determining competitiveness in the market. However, with the explosion of big data, the extraction of value from data is not easy. This is the time Data Mining – a method of data analysis modern – become important tools for businesses to find out the valuable information hidden from that support strategic decisions and optimize business processes.

This article Lac Viet Computing will help you understand Data Mining what isrole of it in business, the engineering, data mining, common, the same challenges, and specific solutions when deployed business help you take maximum advantage of the power of data to reach on the development process.

1. Data Mining what is?

Data Mining (data mining) is the process to discover, analyze and extract useful information from large data sets. Through the use of tools, techniques such as statistics, machine learning (machine learning), artificial intelligence (AI), data mining helps to identify patterns, trends or relationships implicit in the data that previously was not easy to get out.

The origins of Data Mining derived from areas such as:

• Statistics: Used for the analysis and data modeling.
• Artificial intelligence: Use smart algorithms to process and learn from data.
• Management system database: Store and manage large data sets, support information extraction efficiency.

Illustrative examples: Imagine a retail business, there are data on the buying behavior of customers in the past 5 years. Through data mining, businesses can detect that customers often buy products A and B together, from which deploy campaigns, cross-selling (cross-selling) efficiency.

2. Benefits of Data Mining for business

Evidence practices showed the important role of Data mining in business

According to Gartner, the business applying Data Mining in business processes has increased performance by 25%. This is thanks to the ability to detect quickly the opportunities and risks in the data, to help businesses react in time before the fluctuations of the market.

Data from McKinsey: A study by McKinsey indicates that:

• 80% of businesses apply Data Mining has significantly improved the ability to predict the market.
• 73% of business leaders believe that data mining help them make strategic decisions better, particularly in the forecast customer demand and optimize costs.

2.1 minimize business risks by analyzing historical data

Data mining helps businesses use historical data to analyze patterns and trends. Through it, businesses can detect potential risks in business activities such as drop in revenue, changes in customer behavior, or supply chain interruption.

For example, A bank using Data Mining to analyze the credit history of the customer. The results showed that a group of customers tend to delay payments when interest rates exceed a certain threshold. Bank from that adjustment lending policies to minimize the risk of bad debts.

2.2 Forecast consumer trends and market changes

With the ability to analyze real-time data, Data Mining help businesses predict consumer trends in the future. This is extremely important in the industry competitive as retail, technology, real estate.

For example, A company, e-commerce, data analysis, shopping in the occasion to forecast consumer trends. The results help them increase reserves-selling products, reduce inventory not needed, optimize revenue.

Data mining provides the overview angle support business to predict the future trends. For example:

• Banking sector: Predicting credit risk, based on transaction history.
• Manufacturing industry: Detect potential problems in the supply chain to improve operational efficiency.
• E-commerce: Hint products in accordance with customer preferences.

2.3 analysis of behavior, customer preferences

Data Mining provides the enterprise with a holistic view of customer behavior, including the products they usually buy time they shop, factors influencing purchasing decisions.

For example: A store online retailers use Data Mining to detect that the customer usually add products to cart in the evening, but complete the transaction in the morning. Thanks to that store, implement campaigns reminders via email in the morning to increase the percentage of completed orders.

2.4 personalize the shopping experience, increase satisfaction and customer retention

Through the mining of personal data and transaction history, businesses can personalize each customer experience, such as product suggestions fit, send notifications promotion right time or to provide after-sales service better.

For example: Netflix uses Data Mining to analyze the movie-watching habits of users, from which hints of movies and series in accordance with individual preferences, helps to increase the user experience but also help Netflix to sustain high rates of customer retention at a high level, up to 25%.

2.5 detection of points of congestion in the supply chain and optimize operating

Data mining helps businesses track the whole process from production to distribution, to detect points of congestion in the supply chain. This does not only reduce operating costs but also ensure transparency in business operations.

For example, A logistics company, and apply Data Mining to data analysis, shipping, thereby realize that the order in the city was delayed due to the delivery route is not optimal. After adjustment for route delivery time, reduced by 15%.

2.6 application in risk management and financial fraud

Support detection of abnormal behavior in finance, such as fraudulent transactions or activities not valid.

For example, A credit card companies use Data Mining to detect unusual transactions, such as buying high value items in different locations in a short period of time. Automated system alerts and pause the transaction to verify with the customer.
