    Study Notes

    Data Warehouse Architecture

    • Based on a Relational database management system (RDBMS) server that functions as the central repository for informational data.

    Key Components

    • Operational data and processing are completely separate from data warehouse processing.
    • The central repository is surrounded by components that make the environment functional, manageable, and accessible.

    Data Sources

    • Source data typically comes from operational applications or an operational data store (ODS).

    Data Transformation

    • Data is transformed into an integrated structure and format as it enters the data warehouse.
    • Transformation process involves:
      • Data conversion
      • Summarization
      • Filtering
      • Data condensation

    Data Characteristics

    • Data within the data warehouse contains a large historical component, often spanning 5 to 10 years.
