Thus in EAI, "integration" includes both semantic and non-semantic actions, and an "integration layer" can perform both.
因此，在EAI中“集成”包括语义和非语义操作，“集成层”可以执行这两类操作。
In SOA, as in mature EAI, separation of concerns is key, and thus an "integration layer" in SOA might perform both semantic and non-semantic actions, but must keep them separate architecturally.
与成熟的EAI一样，在SOA中关注点隔离是关键，因此soa中的“集成层”可以执行语义和非语义这两类操作，但是必须在架构层面上把它们隔离开。
Backtracking and semantic actions do not mix well.
