    Study Notes

    Business Intelligence

    • Primary Goal of BI: Enhancing decision-making with data-driven insights
    • DSS (Decision Support System): Provides information to support tactical decisions.
    • Model-Driven DSS: Uses complex algorithms and simulations to see the impact of decisions.
    • BI vs. Traditional Reporting: BI offers both descriptive (summarizing past data) and predictive insights, while traditional reporting tools only summarize past data.
    • Performance Dashboard: This component of BI architecture provides data visualization capabilities.
    • Benefits of Data-Driven Decision-Making: Allows decisions based on real-time data insights.
    • Example of Model-Driven DSS: A business can use Model-Driven DSS to simulate various pricing strategies to maximize profit.
    • Applying DSS to Improve Supply Chain Management: Analyzing data related to logistics and inventory levels.
    • BI Tools for Marketing Campaign Enhancement: Segmenting customer data for targeted advertising.
    • Data-Driven Decision Making: Analyzing data with DSS, like increasing marketing expenditures but not seeing an increase in sales, requires review of customer demographics and preferences.

    Data Warehousing

    • Purpose of a Data Warehouse: To store and manage historical data for analysis.
    • Essential Component for Data Warehousing: Data integration tools
    • ETL: Extract, Transform, Load. This process prepares data for the data warehouse
    • Data Integration Importance: It allows for a unified view of data from different sources.
    • Differences Between Data Warehouses and Traditional Databases: Data warehouses support complex queries and analytics over historical data.
    • Staging Area in Data Warehousing: A temporary storage area for data during the ETL process
    • Considerations during the ETL Process: The quality and source of incoming data.
    • Data Warehouse Use in Sales Analysis: Analyzing historical sales data to forecast future sales.
    • Prioritization in Data Warehouse Evaluation: Data accuracy and retrieval speed.
    • Analysis if Data Warehouse Doesn't Yield Insights: Investigate the quality and relevance of the data being input.

    Data Visualization

    • Purpose of Data Visualization: Communicating complex data clearly and effectively.
    • Common Data Visualization Tool: Microsoft Excel.
    • Dashboard in Data Visualization: A visual display of key metrics and performance indicators.
    • Line Graph: The best visualization technique for showing trends over time.
    • Pie Chart: The ideal chart for comparing parts of a whole.
    • Visual Analytics: Using visual methods to understand and analyze data.
    • Benefits of Color in Data Visualization: Highlighting important information and differentiating data points.
    • Balanced Scorecard: Used in business performance management, it includes metrics across financial, customer, internal processes, and learning/growth perspectives.
    • Scatter Plot: The best visualization method for illustrating the relationship between two quantitative variables.
    • How Data Visualization Improves Decision-Making: By making data more accessible and understandable.
    • Importance of Considering the Audience When Creating a Data Visualization: Different audiences may prefer different data formats.
    • Challenge When Using Visualizations to Present Data: Ensuring that visualizations do not mislead the audience.
    • Heat Map: Most useful for showing the distribution of data points over geographic regions.
    • Drawback of Using 3D Visualizations: They can make it harder to accurately interpret the data.
    • Role of Storytelling in Data Visualization: It enhances the understanding and engagement of the audience.
    • Principle Guiding Effective Data Visualization Design: Prioritize simplicity and clarity.
    • When to Choose a Bar Chart Over a Pie Chart: When comparing multiple categories or groups.
    • Purpose of Annotations in Data Visualizations: To provide additional context and insights to the audience.
    • Identifying the Highest-Performing Region: Use a Bar chart to present sales data for different regions.
    • Improving Customer Satisfaction Using Data Visualization: Analyze customer feedback data to identify trends and areas for improvement.
