    Study Notes

    Data Governance and Management

    • Data lakehouses enforce schemas, ensuring that data conforms to a predefined structure, reducing the risk of inconsistent or malformed data.
    • Tracking data lineage allows for understanding data origin, transformations, and usage, crucial for maintaining data quality and compliance.

    ACID Transactions

    • Data lakehouses support ACID transactions, guaranteeing that all data operations are completed successfully and consistently, preventing partial updates and maintaining data integrity.
    • ACID transactions enable concurrent read and write operations without compromising data quality.

    Fine-Grained Access Controls

    • Data lakehouses implement fine-grained access controls, allowing administrators to set granular permissions, ensuring only authorized users can access or modify data.
    • Detailed access logs and audit trails monitor data usage and identify unauthorized access or changes.

    Data Quality Tools

    • Data lakehouses include built-in tools for validation and cleansing, identifying and correcting errors in the data before analysis.
    • Regular automated checks monitor data quality and alert users to any issues, ensuring accuracy and reliability.

    Unified Data Management

    • Data lakehouses provide a unified platform for all data types, reducing data silos and ensuring consistent management.
    • Optimized performance for SQL queries and BI-style reporting ensures data is quickly accessible for analysis.

    Data Lakehouse Architecture - Databricks

    • Improved Data Quality: Databricks Data Lakehouse architecture offers significant enhancements in data quality compared to traditional data lakes. This is achieved through stronger data governance, ACID transactions, fine-grained access controls, and built-in data quality tools.

    Data Governance and Management

    • Schema Enforcement: Enforces predefined schemas, reducing inconsistent or malformed data entry.
    • Data Lineage Tracking: Provides clear understanding of data's origin, transformations, and usage, crucial for data quality and compliance.

    ACID Transactions

    • Atomicity, Consistency, Isolation, Durability (ACID): Ensures all data operations complete successfully and consistently, preventing partial updates and maintaining data integrity.
    • Concurrent Operations: Supports concurrent read and write operations without compromising data quality.

    Fine-Grained Access Controls

    • Granular Permissions: Allows administrators to set permissions at specific levels, safeguarding data quality and security.
    • Auditing: Detailed access logs and audit trails monitor data usage and identify unauthorized access or changes.

    Data Quality Tools

    • Validation and Cleansing: Includes built-in tools to identify and correct errors in the data before analysis.
    • Automated Quality Checks: Regular checks monitor data quality and alert users to issues, ensuring accurate and reliable data.

    Unified Data Management

    • Single Source of Truth: Combines data lake and data warehouse capabilities, creating a unified platform for managing all data types. This eliminates data silos, ensuring consistent data management.
    • Optimized Performance: Enhanced performance for SQL queries and BI reporting ensures high-quality data is quickly accessible for analysis.
