Interface description language. IDLs are commonly used in remote procedure call software. In these cases the machines at either end of the "link" may be using different operating systems and computer languages. IDLs offer a bridge between the two different systems. Software systems based on IDLs include Sun's ONC RPC, The Open Group's Distributed Computing Environment, IBM's System Object Model, the Object Management Group's CORBA (which implements OMG IDL, an IDL based on DCE/RPC), Mozilla's XPCOM, Facebook's Thrift and WSDL for Web services. Examples[edit] See also[edit] External links[edit] Enterprise Mashup Markup Language. The primary benefits of EMML are mashup design portability and interoperability of mashup solutions. These benefits are expected to accelerate the adoption of enterprise mashups by creating transferable skills for software developers and reducing vendor lock-in.
The introduction of EMML is expected to help accelerate the trend toward the integration of Web-based applications and service-oriented architecture (SOA) technologies.[1] Bank of America was a high-profile early supporter of EMML.[2] Other prominent early supporters included Hewlett-Packard, Capgemini, Adobe Systems, and Intel.[3] EMML history[edit] EMML features[edit] EMML language provides a rich set of high-level mashup-domain vocabulary to consume and mash a variety of Web data-sources in flexible ways.
High-level EMML language features include: EMML is primarily a XML-based declarative language, but also provides ability to encode complex logic using embedded scripting engines. Directinvoke statement[edit] Sort statement[edit] Staged event-driven architecture. SEDA employs dynamic control to automatically tune runtime parameters (such as the scheduling parameters of each stage) as well as to manage load (like performing adaptive load shedding). Decomposing services into a set of stages also enables modularity and code reuse, as well as the development of debugging tools for complex event-driven applications.

Event-driven SOA. SOA 2.0[edit] SOA 2.0 architecture, ("event-driven SOA"), lets business users monitor, analyze, and enrich events to make the connections among disparate events that do not at first appear to be intuitively obvious.
This makes these enriched events visible to others, especially business analysts or marketing directors, and also allows the SOA 2.0 system to possibly automate actions to take to address some unique pattern.[1] 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. In practice, this relationship of streamed events is processed through a causal vector engine, which performs a lookup based on recently viewed events and assigns a causal vector to an event if a relationship is discovered. Event-driven architecture. Building applications and systems around an event-driven architecture allows these applications and systems to be constructed in a manner that facilitates more responsiveness, because event-driven systems are, by design, more normalized to unpredictable and asynchronous environments.[2] Event-driven architecture can complement service-oriented architecture (SOA) because services can be activated by triggers fired on incoming events.[2][3] This paradigm is particularly useful whenever the sink does not provide any self-contained executive[clarify].
SOA 2.0 evolves the implications SOA and EDA architectures provide to a richer, more robust level by leveraging previously unknown causal relationships to form a new event pattern. [vague] This new business intelligence pattern triggers further autonomous human or automated processing that adds exponential value to the enterprise by injecting value-added information into the recognized pattern which could not have been achieved previously. ISO/IEC 42010. ISO/IEC/IEEE 42010 Systems and software engineering — Architecture description is an international standard for architecture descriptions of systems and software. Overview[edit] ISO/IEC/IEEE 42010:2011 defines requirements on the description of system, software and enterprise architectures.
It aims to standardise the practice of architecture description by defining standard terms, presenting a conceptual foundation for expressing, communicating and reviewing architectures and specifying requirements that apply to architecture descriptions, architecture frameworks and architecture description languages. Following its predecessor, IEEE Std 1471, the standard makes a strict distinction between Architectures and Architecture Descriptions.
The description of ISO/IEC/IEEE 42010 in this article is based upon the standard published in 2011.[1] Terminology[edit] ISO/IEC 42010 defines a number of terms: Conceptual Foundations[edit] The ISO/IEC/IEEE 42010 conceptual model utilizes the following concepts: ArchiMate. Insurance claim process depicted in ArchiMate. Archimate enables modelling in different layers. ArchiMate (/ˈɑr.kɪmeɪt/ AR-ki-mayt) is an open and independent enterprise architecture modeling language to support the description, analysis and visualization of architecture within and across business domains[1] in an unambiguous way. ArchiMate is a technical standard from The Open Group and is based on the concepts of the IEEE 1471 standard. It is supported by various tool vendors and consulting firms. ArchiMate distinguishes itself from other languages such as Unified Modeling Language (UML) and Business Process Modeling Notation (BPMN) by its enterprise modelling scope.[3] Overview[edit] ArchiMate offers a common language for describing the construction and operation of business processes, organizational structures, information flows, IT systems, and technical infrastructure.
An architecture framework is used to structure the concepts and relationships of the ArchiMate language. Orchestra: Open Source BPEL / BPM Solution - Orchestra : The Open Source BPEL solution. Bridging the Gap. Welcome to Pegasus | Pegasus. [Business] Narrative Modelling Language.
