Trust Parameters

Trust Parameters

You can define the following trust parameters:
minimumTrust
Trust level that a data value has when it is old (after the decay period has elapsed). This value must be less than or equal to the maximum trust.
If the maximum and minimum trust are equal, then the decay curve is a flat line, and the decay period and decay type have no effect.
maximumTrust
Trust level that a data value has if it has just been changed. For example, if source system X changes a phone number field from 555-1234 to 555-4321, the new value gets system X’s maximum trust level for the phone number field. By setting the maximum trust level relatively high, you can ensure that changes in the source systems are applied to the base object.
timeUnit
Specifies the units used in calculating the decay period—day, week, month, quarter, or year.
maximumTimeUnits
Specifies the number — of days, weeks, months, quarters, or years — used in calculating the decay period.
graphType
Decay follows a pattern in which the trust level decreases during the decay period. The graph types can be one of the following decay patterns:
Graph Type Parameter
Description
LINEAR
Simplest decay. Decay follows a straight line from the maximum trust to the minimum trust.
RISL
Most of the decrease occurs toward the beginning of the decay period. Decay follows a concave curve. If a source system has this graph type, then a new value from the system will probably be trusted, but this value might be overridden.
SIRL
Most of the decrease occurs toward the end of the decay period. Decay follows a convex curve. If a source system has this graph type, it will be relatively unlikely for any other system to override the value in the master record until the value is near the end of its decay period.
