Executable choreography
open-in-new
<p>Executable choreography represents a decentralized form of <a href="/facts/Service_composability_principle/bvKlsbAq">service composition</a>, involving the cooperation of several individual entities. It is an improved form of <a href="/facts/Service_choreography/Vy95NlMn">service choreography</a>. Executable choreographies can be intuitively seen as arbitrary complex workflows that get executed in systems belonging to multiple organisations or authorities. </p><p>Executable choreographies are actual codes created to encode system behavior from a global point of view. The behavior of the main entities in a system is given in a single program. Choreographies enhance the quality of software, as they behave like executable blueprints of how communicating systems should behave and offer a concise view of the message flows enacted by a system. </p>
