Study Notes
Contemporary Data Practices
- Data analysis is the process of examining datasets to find trends and draw conclusions.
- Data analysis is used in business to make better decisions, identify top-selling products, and assist the research sector in validating theories.
- Descriptive analytics summarizes and organizes data to provide valuable insights, describing, explaining, and presenting key dataset characteristics to understand key themes.
- Benefits of descriptive analysis include understanding trends, summarizing data, identifying anomalies, and understanding trends in product sales via seasons.
- Data visualization is the visual representation of data through charts, graphs, and histograms. This method plots common themes from descriptive analysis.
- A Management Information System (MIS) is a collection of people, procedures, and resources designed to support managerial decisions.
- MIS structures basic data into reports for decision-making guidance.
- MIS systems contain information from company operations, including sales figures, expenses, investments, and workforce data.
- What-if scenarios show how variables change with decisions made. These can include reduced staff levels or increased budgets, showing their impact on revenue, expenses, and profit.
- Decisions affect company projections and may necessitate strategy modifications.
- Trend analysis is available within or enabled by management information systems for evaluating decision effects on company projections.
- Typical business strategies incorporate projections for fundamental operating results.
Project Management Software
- Project Management Software assists with project planning, execution, monitoring, and control.
- Key features include setting the critical path of the project by defining the sequence of essential tasks. Delays in these tasks can cause project delays.
- Visualizing interdependent tasks ensures the correct order of completion for tasks relying on each other.
- The project schedule is the plan or roadmap for the project.
- Milestones, mini-deadlines or checkpoints, ensure essential tasks are completed. Task breakdown divides milestones into smaller, manageable tasks.
- Software allows staff allocation for a task’s responsibility/accountability, and allocation to specific team members based on skills.
- Allocation of resources (books, technology, money, and time) is needed for task completion.
Data Warehouse
- A data warehouse is a centralized repository for large structured data volumes from diverse sources.
- Data is organized and optimized for efficient retrieval and analysis.
- Technologies used for holding large amounts of data are referred to as 'data warehouses.'
- Extract, transform, load (ETL) data warehouses use three layers: staging, integration, and access.
- The staging layer stores raw extracted data from different source systems.
- The integration layer transforms data from the staging layer.
- The access layer allows data retrieval.
- Extract, Load, Transform (ELT) data warehouses combine data extraction, transformation, and loading into one process, efficiently loading data into the same warehouse.
- Data warehouses are designed for reporting and data analysis to support informed business decisions.
- A retail company example demonstrates consolidation of multiple store, online, and customer review data to analyze trends, track inventory, and optimize pricing across the business.
Data Mining
- Data mining discovers patterns, trends, and valuable insights from large datasets. Techniques include statistical analysis, machine learning, and pattern recognition.
- Data mining gains information from massive amounts of data.
- A social media platform example shows data mining use for analyzing user behavior and interactions to personalize news feeds, target advertisements, and enhance user engagement.
Big Data
- Big data, or large datasets, are expansive and complex that traditional data processing methods cannot manage or analyze effectively.
- Sources include modern devices like mobile phones and the internet.
- Big data characteristics include volume (quantity), variety (mix of data types), velocity (rapid data generation), and complexity (hard to process and understand).
- Validity (correct accuracy for intended use) is important for large data sets.
- Meteorological data analysis, using data from satellites, weather stations, helps in forecasting weather patterns, predicting storms, and issuing community warnings.
Exam Questions
- Describe how large datasets can be analyzed and used. (4 marks)
Cloud Delivery Systems - Without CDN
- User requests go to a single server.
- Slower loading speeds due to the increased distance data travels.
- Potential server performance and downtime issues due to high server load.
Cloud Delivery Systems - With CDN
- Content is replicated and hosted on multiple servers globally for faster access.
- Users are directed to the nearest server (Point of Presence - PoP) for quicker access.
- Data transmission time is significantly reduced.
- Load and traffic are distributed across numerous servers for enhanced performance.
- System scalability is possible by adding servers.
