  • Ideal for time-series data, IoT telemetry, social analytics, and real-time dashboards.

Use Case:
An oil and gas company stores continuous sensor readings (pressure, temperature) from multiple plants in Cassandra to predict equipment failure.

MongoDB

  • Stores unstructured or semi-structured data as JSON-like documents.
  • Flexible schema and fast queries for customer behavior analysis, web analytics, and product catalogs.

Use Case:
An e-commerce platform uses MongoDB to store product reviews and perform sentiment analysis for product improvement and recommendation.

3.3 Python and R for Data Science

Python

  • Key libraries: Pandas, NumPy, Scikit-learn, TensorFlow, PyTorch, Matplotlib.
  • Used for data cleaning, feature engineering, and model deployment.

Use Case:
A marketing analytics firm builds customer churn prediction models using Scikit-learn logistic regression and XGBoost, improving retention by 18%.

R

  • Popular for advanced statistical modeling and visualization.
  • Libraries: ggplot2, dplyr, caret, forecast, randomForest.

Use Case:
A financial institution uses R forecast to analyze macroeconomic indicators and predict interest rate fluctuations.

4. Data Mining and Predictive Analytics Pipeline

The complete Data Mining Process involves:

  1. Data Collection – Integrate data from CRM, ERP, sensors, and web applications.
  2. Data Preprocessing – Handle missing values, normalize, and remove outliers using Python Pandas.
  3. Feature Engineering – Identify key predictive variables.
  4. Model Building – Use ML algorithms like Random Forest, SVM, or Gradient Boosting.
  5. Validation – Evaluate with cross-validation and ROC-AUC metrics.
  6. Deployment – Serve predictive models using Flask, FastAPI, or R Shiny.

Predictive analytics techniques include:

  • Regression models – Forecasting sales and pricing trends.
  • Classification – Lead scoring, fraud detection.
  • Clustering – Customer segmentation.
  • Association rule mining – Market basket analysis.
  • Time-series forecasting – Demand prediction using ARIMA/LSTM.
