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.
