Baseline or Managed Collection?
Managed collections and baselines are similar objects. Both capture information related to a specific point in time.
Baseline
Use a baseline if you are primarily interested in capturing information related to a specific point in time. You intend to create a new baseline for every milestone, event, or date.
Managed Collection
Use a managed collection if you are primarily interested in grouping objects together so that they can be viewed from a central location. You intend to periodically update the objects within the managed collection.
