    Study Notes

    Data Security and Management

    • Data security ensures vital company information is backed up and retrievable if the primary source is unavailable.
    • Data catalogs manage metadata, providing summaries of data changes, locations, and quality to facilitate easy data discovery.
    • Data warehouses consolidate various data sources, allowing for diverse data type handling and streamlined data analysis.
    • Data governance establishes standards, processes, and policies to ensure data security and integrity, addressing compliance with consumer protection laws when handling personally identifiable information.

    Data Handling and Evolution

    • Effective data management is critical in the digital economy; systems must evolve to meet organizational data needs.
    • Modern data management software tackles challenges in governance, scalability, and security to ensure trusted data availability.
    • Traditional data management methods hinder scaling capabilities; agile systems improve efficiency by minimizing duplication of research and unnecessary costs.

    Data Integration and Visualization

    • Data integration involves merging disparate data sources into a unified view, enhancing analytical capabilities for businesses.
    • The process consists of data cleaning, transformation, and merging to convert raw data into a cohesive dataset.
    • Visualization tools, like bar charts and heat maps, simplify complex data, revealing trends and aiding strategic planning without requiring extensive manual input.

    Data Storage Methods

    • Floppy disks, CDs, DVDs, USB flash drives, and external hard drives represent various data storage solutions, each with unique attributes for portability and capacity.
