– From an outreach perspective: From an outreach perspective: Minimize time between student status change, such as Minimize time between student status change, such as

dropping below 13 credits, and follow-up from dropping below 13 credits, and follow-up from adviser/counselor/etcadviser/counselor/etc

DW data reflects “current” state; ODS is a DW data reflects “current” state; ODS is a transaction log transaction log merging the two can be non-trivial merging the two can be non-trivial– First, we extracted the most recent “state” from ODS (from First, we extracted the most recent “state” from ODS (from

O_PS_STDNT_ENRL_D, for example) O_PS_STDNT_ENRL_D, for example) – Second, when extracted records conflicted with DW Second, when extracted records conflicted with DW
