    Study Notes

    Versioning in SQL API

    • SQL API can provide historical data using columns gsr_ldts and gsr_sdts.
    • Information marts often only include the latest version, sometimes omitting gsr_ldts and gsr_sdts.
    • Historical data can be filtered based on specific criteria.
    • Use an INNER JOIN with a control table to filter by version:
    inner join control.control_ldts cl on 
    cl.gsr_client = x.gsr_client and cl.gsr_inst = x.gsr_inst 
    and cl.gsr_ldts = x.gsr_ldts and cl.is_latest

    Versioning in Flow.BI

    • Flow.BI manages historical data, schemas, and metadata through versioning, maintaining and managing historical records or multiple versions of data, schema, or metadata.
    • Tracks changes, enabling better control, auditing, and historical analysis.

    Types of Versioning

    • Metadata Versioning: Tracks changes to metadata (data definitions, rules, lineage).
    • Report Versioning: Keeps track of report/dashboard changes (e.g., lineage report versions, comparing how metrics and designs have evolved).

    Importance of Versioning

    • Historical Analysis: Allows studying data trends over time, enabling analysis of data trends and changes over time.
    • Auditing and Compliance: Provides an audit trail for regulatory requirements, ensuring transparency and accountability.
    • Rollback Capability: Allows reverting to previous versions.
    • Data Consistency and Integrity: Ensures consistency between historical and current data, ensuring that historical and current data remain consistent and aligned with the business's needs.
    • Impact Analysis: Helps understand how changes affect downstream processes (reports, dashboards), helping in understanding the effect of schema or data changes on downstream processes.
    • Versioning in Flow.BI is crucial for data management and analytics, preserving historical data, and supporting data governance. It's a critical component for effective data management and analytics.
