Loose coupling is an architectural principle and design goal in service-oriented architectures. Eleven forms of loose coupling and their tight coupling counterparts are listed in: [4] physical connections via mediator, asynchronous communication style, simple common types only in data model, weak type system, data-centric and self-contained ...
Another major problem faced by SOA is the lack of a uniform testing framework. There are no tools that provide the required features for testing these services in a service-oriented architecture. The major causes of difficulty are: [39] Heterogeneity and complexity of solution. Huge set of testing combinations due to integration of autonomous ...
The term service-oriented programming was first published in 2002 by Alberto Sillitti, Tullio Vernazza and Giancarlo Succi in a book called "Software Reuse: Methods, Techniques, and Tools." SOP, as described above, reflects some aspects of the use of the term proposed by Sillitti, Vernazza and Succi.
SOA 2.0 is the ability to create high-level business events from numerous low-level system events. Events are created by filtering real-time data (from middleware, applications, databases, and Web services, for example) and infusing it with defining detail such as dependencies or causal relationships discovered by correlating other events.
The OASIS Reference Model for Service Oriented Architecture [1] (SOA-RM) is an abstract framework for understanding significant entities and relationships between them within a service-oriented environment, and for the development of consistent standards or specifications supporting that environment. It is based on unifying concepts of SOA and ...

Service-oriented design and development methodology (SDDM) is a fusion method created and compiled by M. Papazoglou and W.J. van den Heuvel. [1] The paper argues that SOA designers and service developers cannot be expected to oversee a complex service-oriented development project without relying on a sound design and development methodology.
An enterprise service bus (ESB) implements a communication system between mutually interacting software applications in a service-oriented architecture (SOA). It represents a software architecture for distributed computing, and is a special variant of the more general client-server model, wherein any application may behave as server or client ...
