Executable Choreography
Executable choreography represents a decentralized form of Service composability principle, service composition, involving the cooperation of several individual entities. It is an improved form of service choreography. Executable choreographies can be intuitively seen as arbitrary complex workflows that get executed in systems belonging to multiple organisations or authorities. 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. Executable vs. non-executable choreography In almost all applications the business logic must be separated into different services. The Orchestration (computing), orchestration represents the way that these services are organize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Service Composability Principle
In computing, service composability is a design principle, applied within the service-orientation design paradigm, that encourages the design of services that can be reused in multiple solutions that are themselves made up of composed services. The ability to recompose the service is ideally independent of the size and complexity of the service composition. This principle is directly responsible for the agility promised by SOA as it promotes composing new solutions by reusing existing services.Michael PouliEvolution of principles of Service Orientation: Service Statelessness, part 7Online].Date accessed: 21 April 2010. Purpose The concept of developing software out of independently existing components encourages the concept of composition. This is the underlying concept within object-orientation where the end product is composed of several interlinked objects that have the ability to become part of multiple software solutions, no matter how complex the solution is. The same compo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
