About Trust

About Trust

Several source systems may contain attributes that correspond to the same column in a base object table.
For example, several systems may store a customer’s address. However, one system might be a more reliable source for that data than others. If these systems disagree, then
Informatica MDM Hub
 must decide which value is the best one to use.
To help with comparing the relative reliability of column data from different source systems,
Informatica MDM Hub
 allows you to configure trust for a column. Trust is a designation the confidence in the relative accuracy of a particular piece of data. For each column from each source, you can define a trust level represented by a number between 0 and 100, with zero being the least trustworthy and 100 being the most trustworthy. By itself, this number has no meaning. It becomes meaningful only when compared with another trust number to determine which is higher.
Trust takes into account the age of data, how much its reliability has decayed over time, and the validity of the data. Trust is used to determine survivorship (when two records are consolidated), and whether updates from a source system are sufficiently reliable to update the master record.
