soa - Difference between service orchestration, aggregation and service augmentation -


what difference between service orchestration , aggregation? in similar post on so, mentioned there thin line between these 2 terms. possible more details thin line? also, service augmentation , how relate 2 other 2 concepts.

service orchestration coordination or integration of several services expose single service.

service augmentantion used within service message enrichment. suppose based on client id need obtain additional data, address, email or phone, should augment message using database queries, etc..
