title: Can a service call another service inside its code?
body: <p>Following is a point mentioned in a presentation slide related to SOA, and it confuses me with the concepts of service orchestration and service choreography. To enable service choreography, shouldn't a web service be able to call another web service?</p>
  
  <pre><code>SOA builds applications out of software services. Services comprise intrinsically
  unassociated, loosely coupled units of functionality that have no calls to
  each other embedded in them.
