    Study Notes

    OEG Best Practice: Data Hubs

    • Data Hubs are models that store transactional data from source systems, ensuring data accuracy and providing a single source of truth.
    • Key advantages of a Data Hub include:
      • A single source of truth for transactional data.
      • Data validation before being loaded into spoke models.
      • Improved performance when loading data from a model versus a file.
      • The ability to aggregate data to different granularities (e.g., daily to monthly).

    Data Hub Definition

    • A Data Hub is a central model containing transactional data from various source systems.
    • Four key sections of a Data Hub definition include use cases, model connectivity, functions, and team roles.
    • Use cases: The Data Hub is designed to be the initial model, used for single or multiple uses on a regular schedule (like daily, weekly).
    • Model connectivity: Utilizes tools like Informatica Cloud, Dell Boomi, Mulesoft, or SnapLogic, or an API to automate data transfer.

    Anaplan Architecture with a Data Hub

    • Several architectures are possible, depending on workspace structure and security needs.
    • Master Hub Model (across workspaces): The Data Hub is housed in its own workspace, separating it from other models and adding a security layer. This is the recommended approach.
    • Master Hub Model (within a workspace): The Data Hub is within the same workspace as spoke models.
    • Multiple Data Hubs: More than one data hub can be used, for example when needed, in a workspace.

    Factors to Consider when Implementing a Data Hub

    • User stories: Understand the types of data needed, granularity, historical data requirements, and system capabilities.
    • Source systems: Identify the source systems and data needs along with the preparation for file specifications.
    • Data Validation: The Data Hub should ensure data quality through checks, transformations, or other procedures.
    • Exporting to spoke models: Data Hub exports data to specific spoke models based on requirements and ensures consistent data presentation.

    Loading data vs. Formulas in SYS Modules

    • Loading data is often slower than using formulas in SYS modules, particularly with large data volumes.
    • Loading data triggers change logs, recording every action in the model history.
    • Formulas, if correctly constructed, can be faster for retrieving data than loading and then filtering.

    Exporting data to spoke models

    • Export modules aggregate data to the appropriate granularity; this improves Spokes Model loading.
    • Data transformation functions can be used to map, consolidate, and transform data for accurate loading into spoke models (this optimizes format).
    • Spoke models avoid loading raw data and instead load the appropriate granular format.

    Tips and Tricks

    • Avoid hierarchies in the hub.
    • Do not delete and reload lists inside the hub (this affects performance).
    • Focus on validation inside the Data Hub; this avoids redundant validation logic in spoke models.
