Setting source values and data decay

The purpose of source values is to establish a standardized approach to store and retrieve information, or values, that come from an external sources when the attributes of those values do not fit the structure of your implementation.

Source values allow you to identify the system, application, or user that provided the value. It also stores the date the value was collected, as well as a history of the source that provided the value and the date when that value changes.

The source value system must add, update and get the following type of information within InfoSphere® MDM:

• Record the source system, application or user that provided the specified function details, for example privacy preference, campaign, and others.
• Record the date when the information is collected.
• Keep a history of the source and source date.

The source value system is in several areas within InfoSphere MDM. The source value system works with any entity. It is also included in the specific function transaction. For example, when a change is made to a party's privacy preference, source value system is a part of the function transaction. The source value system is required in the following function areas:

• Privacy Preference
• Campaigns
• Source System is also included in seven entities in core Party Module. These entities are:
  • Person
  • Organization
  • Person Name
  • Organization Name
  • Party Identification
  • Party Contact Method
  • Party Address

All data and service-level extension points are available to extend source values and data decay.
