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.
- Ensuring Effectiveness When Preparing a Presentation with Multiple Data Visualizations: Each visualization should have a clear purpose and support the overall message.
- Illustrating Growth of Revenue Over Five Years: Use a Line Graph to show revenue growth over time.
- Investigating Unexpected Sales Drops: Analyze underlying data to determine the cause.
- Critical Factor in Dashboard Evaluation: User feedback on ease of use and clarity of information.
- Assessment If Visualization Leads to Misinterpretation: Assess the clarity and design of the visualization.
