• Structured data: Tabular data stored in relational databases (customer records, sales transactions)
• Unstructured data: Text, images, videos, and social media posts

ETL processes

• ETL (Extract, Transform, Load) is the process of extracting data from source systems, transforming it into a consistent format, and loading it into a target system
• Extraction: Retrieving data from various sources (databases, flat files, APIs)
• Transformation: Cleansing, standardizing, and enriching data to ensure consistency and quality
• Loading: Inserting transformed data into the target system (data warehouse, data mart)

Data warehousing concepts

• A data warehouse is a centralized repository that stores integrated data from multiple sources for reporting and analysis
• Enables organizations to separate analytical workloads from transactional systems and optimize performance
• Key concepts include:

Data analysis techniques

• Data analysis techniques are used to extract insights and patterns from data to support decision-making
• BI leverages a range of analytical techniques, from basic reporting to advanced machine learning algorithms
• Understanding the differences between OLAP and OLTP systems, as well as the role of data mining and predictive analytics, is essential for effective BI

OLAP vs OLTP systems

• OLAP (Online Analytical Processing) systems are optimized for complex queries and analysis of large datasets
  • Designed for read-intensive workloads and multidimensional analysis (slicing, dicing, drilling down)
  • Use denormalized schemas (star, snowflake) to support efficient querying
• OLTP (Online Transaction Processing) systems are designed for handling high volumes of transactions and real-time data updates
  • Optimized for write-intensive workloads and maintaining data integrity
  • Use normalized schemas to minimize data redundancy and ensure consistency

Data mining and predictive analytics

• Data mining involves discovering hidden patterns and relationships in large datasets using statistical and machine learning techniques
• Predictive analytics uses historical data to build models that predict future outcomes and trends
• Common techniques include:
  • Classification: Assigning data points to predefined categories (customer segmentation, fraud detection)
  • Regression: Predicting continuous values based on input variables (sales forecasting, price optimization)
  • Clustering: Grouping similar data points together based on their characteristics (customer profiling, market segmentation)

Machine learning in BI

• Machine learning (ML) is a subset of artificial intelligence that enables systems to learn and improve from experience without being explicitly programmed
• ML algorithms can automatically identify patterns and insights in data, reducing the need for manual analysis
• Applications of ML in BI include:
  • Anomaly detection: Identifying unusual patterns or outliers in data (fraud detection, equipment failure prediction)
  • Recommendation systems: Suggesting products, services, or actions based on user behavior and preferences (personalized marketing, cross-selling)
  • Natural language processing: Extracting insights from unstructured text data (sentiment analysis, customer feedback analysis)

Data visualization and dashboards

• Use a clear and consistent visual hierarchy to guide the user's attention (headlines, labels, annotations)
• Ensure data integrity and accuracy by using appropriate scales and avoiding distortions
• Use color strategically to highlight key insights and distinguish categories
• Simplify complex data by using aggregation, filtering, and drill-down functionality

Dashboard design best practices

• Define clear objectives and target audiences for each dashboard
• Use a logical layout and grouping of related metrics and visualizations
• Provide context and benchmarks to help users interpret the data (targets, industry averages)
• Optimize for performance and usability by minimizing load times and ensuring responsiveness
• Incorporate user feedback and iterate on the design to continuously improve the dashboard

Interactive visualization tools
