You can manage data change events of business entities and their relationships through timeline management. A data change event is a change to data that is effective for a time period. When data change events occur, the
creates versions of an entity instead of overwriting the existing data.
You can define the data change events or versions of business entities and their relationships based on their effective periods. Data changes occur over time and are independent of their relationship to other data. The changes to data result in new effective periods or updates to an existing or a future effective period. Use timeline management to track the changes to effective periods of data.
To manage data events of business entities, such as customer address, phone number, and their relationships, you can enable the timeline. To maintain the effective periods for base object records, the
uses cross-reference tables that are associated with the base objects for which you enabled the timeline.
You enable the timeline for base objects when you configure base object properties in the
Hub Console
. When you enable the timeline, the
tracks past, present, and future changes to data, such as the address of a customer.
Timeline is enabled by default for hierarchy management relationship base objects.
Base objects for which you enable the timeline contain a version of data that pertains to the effective period that you specify. The base objects might not reflect the current values. The version of data in base objects at any point in time depends on the contributing cross-reference tables that might change with time. You can use SIF API calls to get records for the current effective date. Additionally, you can pass any effective date to retrieve the data for the effective date that you specify.
When an incoming change affects the current effective period of the base object, the
uses the current trust settings to recalculate BVT. Then the
updates the base object record.
Hub Server
always uses the current trust settings to calculate the best version of the truth (BVT) for past, present, or future data.
After you enable the timeline for a base object, you cannot disable it. If you enable the timeline for a populated base object, the
Hub Server
sets the effective period start date and end date to null.
