domain D5.L3, which is positioned on the third level in this domain hierarchy. Note that composite
service CO1 also aggregates the atomic service A2, meaning A2 is also part of this business
integration.
Service-oriented business integration can span multiple geographic locations and accommodate
distributed business scenarios. Exhibit 11.19 illustrates a cross-continent service integration
initiative that takes place in two business execution tiers: the T1 European car distribution
tier and the T2 U.S. car distribution tier.
??? T1. This European tier includes luxury and economy car distribution centers that are
operated by two domains: the luxury car distribution center business domain (D1) and
the economy car distribution center business domain (D2.L1) that is also a part of a
hierarchical layered formation that contains the economy car parts center business domain
D3.L2. The economy car parts distribution (A1) and the economy car parts ordering (A2)
atomic services are denoted by the ???integrated??? symbol, which makes them a part of the
economy car parts center business domain.
