Assigning student records to advisors or staff members can be accomplished using staff assignment rules.  These assignments can be based on a variety of criteria including home state, country, last name, geomarket, transfer, etc.  An important consideration when sharing a database with admissions is the timing of the application of the staff assignment rules.  The admissions office likely already has a designated set of staff assignment rules, so the timing of when these new assignment rules run is significant.  It may be most effective to wait to run the rules for currently enrolled students until the point in time when they are considered "current students."  Some may consider this time to be move-in weekend, the first day of classes, or a certain amount of time after a student has submitted their enrollment deposit.
