Aggregation
Aggregation is the process by which data about identities and their access is read from your enterprise systems into IdentityIQ. IdentityIQ aggregates Account data (which includes information about identities and their accounts and entitlements on the outside systems) and Account Group data (which includes account groups and application object types that are the basis for creating entitlements that represent group membership).
IdentityIQ uses configured applications to connect to these enterprise systems, and uses tasks to do the work of reading the data into IdentityIQ and correlating it to identities stored in IdentityIQ
