What is Data Mining?

Data mining is extracting meaningful insights, patterns, and trends from large datasets using machine learning, statistical analysis, and AI techniques. These meaningful insights can be used in decision-making, prediction, and discovering hidden relationships within data.

Syntax:

Since data mining involves different tools and algorithms, there is no fixed syntax. However, the SQL-based data mining query looks like this

-- Syntax for finding frequent items in a departmental store
SELECT 
    A.<product_column> AS product_1, 
    B.<product_column> AS product_2, 
    COUNT(*) AS frequency
FROM <transaction_items_table> A
JOIN <transaction_items_table> B 
    ON A.<transaction_id_column> = B.<transaction_id_column> 
    AND A.<product_column> < B.<product_column>  -- Avoid duplicate pairs
GROUP BY A.<product_column>, B.<product_column>
HAVING COUNT(*) > <min_frequency_threshold>
ORDER BY frequency DESC;

Example:

Consider a scenario where a departmental store wants to identify the customer purchasing patterns. To better understand this, let’s create a table called transaction.

CREATE TABLE transactions (
    transaction_id INT PRIMARY KEY,
    customer_id INT,
    purchase_date DATE
);
INSERT INTO transactions (transaction_id, customer_id, purchase_date) VALUES
(101, 1, '2024-03-20'),
(102, 2, '2024-03-21'),
(103, 1, '2024-03-22'),
(104, 3, '2024-03-23');
Select * from transactions;

This is how the transaction table looks.

Now, let’s create the transaction_items table

CREATE TABLE transaction_items (
    transaction_id INT,
    product_name VARCHAR(255),
    FOREIGN KEY (transaction_id) REFERENCES transactions(transaction_id)
);
INSERT INTO transaction_items (transaction_id, product_name) VALUES
(101, 'Bread'),
(101, 'Butter'),
(102, 'Laptop'),
(102, 'Wireless Mouse'),
(103, 'Bread'),
(103, 'Butter'),
(104, 'Bread');
Select * from transaction_items;

This is how the transaction_items table looks.

-- Query to find frequently bought items
SELECT 
    A.product_name AS product_1, 
    B.product_name AS product_2, 
    COUNT(*) AS frequency
FROM transaction_items A
JOIN transaction_items B 
    ON A.transaction_id = B.transaction_id 
    AND A.product_name < B.product_name  
GROUP BY A.product_name, B.product_name
HAVING COUNT(*) > 1
ORDER BY frequency DESC;

Output:

Explanation: Here, this query self-joins the transaction_items table to determine which product pairs were purchased together in the same transaction and counts how many times they were purchased together. It removes duplicate pairs and returns the items that were frequently purchased together.

Microsoft SQL Server Data Mining

An effective data mining and predictive analytics tool built into SQL Server Analysis Services (SSAS) is Microsoft SQL Server Data Mining (SSAS Data Mining). It allows organizations the ability to detect patterns, trends, and relationships in large amounts of data with SQL-based machine learning.

Features of SSAS Data Mining

• SQL Server Analysis Services (SSAS): It provides SQL Server data mining algorithm that allows for the analysis of multidimensional data using OLAP (Online Analytical Processing).
• Data Mining Model Designer: A drag-and-drop environment in SQL Server Data Tools (SSDT) to develop the models.
• Data Mining: Model capabilities can be implemented for real-time predictions on live data during the run in SQL Server.
• Integrating with Microsoft Power BI: Allows integration with Azure Machine Learning for AI capabilities from the cloud. It works efficiently with Power BI, Excel data mining, and SSRS.
• Performance Optimization: SQL Server’s high-performance engine is designed for enterprise-scale data processing. It also supports integration with Azure Machine learning for cloud-based AI enhancement.

How to use SSAS Data Mining?

Step 1: Enable SSAS

• Install SQL Server Analysis Services and SQL Server Data Tools
• In SSDT, create a new SASS project.

Step 2: Data Preprocessing

• Import the data into the SQL Server Database
• Using SQL queries, clean and preprocess the data

Step 3: Train a Data Mining model

• Select a model type, like a decision tree or clustering, using SSDT’s Data Mining Wizard.
• Train the model using historical data.

Step 4: Validate the model

• To assess model accuracy, precision, and recall, use SSDT visualization tools.
• For performance validation, apply test data.

Step 5: Deploy the model

• For real-time predictions, deploy models to SQL Server. Optimize the performance using parameter tuning.

Advantages of SSAS Data Mining

• Seamless integration can be done with Power BI, Azure AI, and Microsoft BI tools.
• It supports data encryption and access control.
• There is no need for external AI tools.

Disadvantages of SSAS Data Mining

• Limited algorithm choices are available compared to Python, TensorFlow, or Scikit-Learn.
• SASS installation has to be done before.
• It is best suitable for an on-premise SQL Server environment and not for Cloud-Native.

Applications of SSAS Data Mining

• Customer Support and Chatbots: NLP-based virtual assistant and sentiment analysis
• Finance: Fraud Detection, credit card risk management, and stock market analysis
• Cybersecurity: Malware detection and classification.
• Retail and E-commerce:  Recommendation system, Market basket analysis
• Business Intelligence: Customer Segmentation and Market Analysis

Comparison of Different Data Mining Tools

How do you choose the best data mining tool?

• Identify the needs: Based on the use case and data type (structured, unstructured, and semi-structured ), choose the tools efficiently.
• Consider the difficulty level of tools: Opt for a tool that is easy to use and also supports a drag-and-drop interface.
• Check the performance: If you will be working with large data or large data sets, it is good to use a tool that executes in the cloud (e.g., AWS SageMaker, Azure ML) to increase your workloads.
• Assess Cost & Support: With technology, you usually pay for what you get, so remember that there are commercial tools that will have costs, but perhaps have special data mining support. Or, you have open-source tools which could be free to utilize on your own, or use the community support.
• Examine Before Selecting: To make sure open-source tools satisfy your data mining requirements, conduct a pilot project using free trials (commercial tools).

Limitations of Data Mining

• Issues in Data Quality: Inaccurate or biased data leads to incorrect predictions and misleading patterns.
• Expensive Computation: Computation of big data involves the need for heavy hardware and algorithms that are highly optimized, hence costly.
• Complex Implementation: Prerequisite knowledge of statistics, Machine Learning is required, which makes it harder for beginners.
• Security Concern: Security issues or data breaches might happen when mining sensitive data.
• Overfitting: Sometimes models will overfit to the training data, which leads to a poor decision-making process.

Common Mistakes and Best Practices

Common Mistakes:

• Ignoring the quality of data: Using incomplete or biased data leads to a misleading decision-making process.
• Selecting the wrong tool: We need to select the tool according to the size of the dataset. Selecting an inappropriate tool leads to misleading results.
• Ignoring Security: There may be moral and legal repercussions if data privacy laws (GDPR, HIPAA) are broken.

Best Practices

• High-quality data: Ensure that data is cleaned, preprocessed, and validated before applying mining techniques.
• Apply proper model validation: To avoid overfitting, use performance metrics and cross-validation techniques.
• Security: To protect sensitive data, implement role-based security and encryption.

Conclusion

Data mining tools are instrumental in collecting important knowledge from large amounts of data, leading companies and research organizations to make decisions based on data. Select an appropriate tool that is budget-friendly, scalable, easy to use, and integrable. However, success in data mining depends not only on the tool but also on the data quality. Organizations may fully utilize data mining to generate innovation and obtain an advantage by following best practices and avoiding typical mistakes.
