We need to know when a record was added, who added it, when it was last changed, and who last changed it. This applies to all record types, especially Gifts, Constituents, Actions, Proposals, Appeals, Funds, Events, Participants, and more.
For people who manage and maintain databases, this information gives us clues as to whether something was mis-coded. It also helps us identify who needs to be retrained, so we can correct the data entry error patterns. We use this information especially in our monthly reconciliation with our Finance team. Having it accessible from the constituent record is needed for our work.
