BPEL4WS
The Web Services Business Process Execution Language (WS-BPEL), commonly known as BPEL (Business Process Execution Language), is an OASIS standard executable language for specifying actions within business processes with web services. Processes in BPEL export and import information by using web service interfaces exclusively. Overview One can describe Web-service interactions in two ways: as executable business processes and as abstract business processes. # An ''executable business process'': models an actual behavior of a participant in a business interaction. # An ''abstract business process'': is a partially specified process that is not intended to be executed. Contrary to Executable Processes, an Abstract Process may hide some of the required concrete operational details. Abstract Processes serve a descriptive role, with more than one possible use case, including observable behavior and/or process template. WS-BPEL aims to model the behavior of processes, via a lan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Web Services Flow Language
Web Services Flow Language 1.0 (WSFL) was an XML programming language proposed by IBM in 2001 for describing Web services compositions. Language considered two types of compositions. The first type was for describing business processes as a collection of web services and the second was for describing interactions between partners. WSFL was proposed to be layered on top of Web Services Description Language. In 2003 IBM and Microsoft combined WSFL and Xlang to BPEL4WS and submitted it to OASIS for standardization. Oasis published BPEL4WS as WS-BPEL to properly fit the naming of other WS-* There are a variety of specifications associated with web services. These specifications are in varying degrees of maturity and are maintained or supported by various standards bodies and entities. These specifications are the basic web services ... standards.

Business Process Modeling Language
Business Process Modeling Language (BPML) is an XML-based language for business process modeling. It was maintained by the Business Process Management Initiative (BPMI) until June 2005 when BPMI and OMG (Object Management Group) announced the merger of their respective Business Process Management (BPM) activities to form the ''Business Modeling and Integration Domain Task Force'' (BMI DT It is deprecated since 2008. BPML was useful to Object Management Group, OMG in order to enrich UML with process notation. History BPML, a superset of BPEL, was implemented by early stage vendors, such as Intalio Inc., but incumbents such as IBM and Microsoft did not implement BPML in their existing workflow and integration engine implementations like ''BizTalk'' or ''Websphere''. They pushed for the simpler language BPEL. In view of the lack of market acceptance, the BPMI dropped support of BPML in favor of BPEL4WS. Following the merger of BPMI and OMG, BPML will be definitively deprecated in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Service Choreography
Service choreography in business computing is a form of service composition in which the interaction protocol between several partner services is defined from a global perspective. The idea underlying the notion of service choreography can be summarised as follows: "Dancers dance following a global scenario without a single point of control" That is, at run-time each participant in a service choreography executes its part according to the behavior of the other participants. A choreography's role specifies the expected messaging behavior of the participants that will play it in terms of the sequencing and timing of the messages that they can consume and produce. Choreography describes the sequence and conditions in which the data is exchanged between two or more participants in order to meet some useful purpose. Service choreography and service orchestration Service choreography is better understood through the comparison with another paradigm of service composition: service orch ...

Structured Programming
Structured programming is a programming paradigm aimed at improving the clarity, quality, and development time of a computer program by making extensive use of the structured control flow constructs of selection ( if/then/else) and repetition ( while and for), block structures, and subroutines. It emerged in the late 1950s with the appearance of the ALGOL 58 and ALGOL 60 programming languages, with the latter including support for block structures. Contributing factors to its popularity and widespread acceptance, at first in academia and later among practitioners, include the discovery of what is now known as the structured program theorem in 1966, and the publication of the influential "Go To Statement Considered Harmful" open letter in 1968 by Dutch computer scientist Edsger W. Dijkstra, who coined the term "structured programming". Structured programming is most frequently used with deviations that allow for clearer programs in some particular cases, such as when exc ...

XPath
XPath (XML Path Language) is an expression language designed to support the query or transformation of XML documents. It was defined by the World Wide Web Consortium (W3C) and can be used to compute values (e.g., strings, numbers, or Boolean values) from the content of an XML document. Support for XPath exists in applications that support XML, such as web browsers, and many programming languages. Overview The XPath language is based on a tree representation of the XML document, and provides the ability to navigate around the tree, selecting nodes by a variety of criteria. In popular use (though not in the official specification), an XPath expression is often referred to simply as "an XPath". Originally motivated by a desire to provide a common syntax and behavior model between XPointer and XSLT, subsets of the XPath query language are used in other W3C specifications such as XML Schema, XForms and the Internationalization Tag Set (ITS). XPath has been adopted by a number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Orchestration (computing)
In system administration, orchestration is the automated configuration, coordination, and management of computer systems and software.Erl, Thomas (2005) Service-Oriented Architecture: Concepts, Technology & Design. ''Prentice Hall'', . A number of tools exist for automation of server configuration and management, including Kubernetes, Ansible, Puppet, Salt, Terraform, and AWS CloudFormation. Usage Orchestration is often discussed in the context of service-oriented architecture, virtualization, provisioning, converged infrastructure and dynamic data center topics. Orchestration in this sense is about aligning the business request with the applications, data, and infrastructure. In the context of cloud computing, the main difference between workflow automation and orchestration is that workflows are processed and completed as processes within a single domain for automation purposes, whereas orchestration includes a workflow and provides a directed action towards larger goal ...

Web Services Description Language
The Web Services Description Language (WSDL ) is an XML-based interface description language that is used for describing the functionality offered by a web service. The acronym is also used for any specific WSDL description of a web service (also referred to as a ''WSDL file''), which provides a machine-readable description of how the service can be called, what parameters it expects, and what data structures it returns. Therefore, its purpose is roughly similar to that of a type signature in a programming language. The latest version of WSDL, which became a W3C recommendation in 2007, is WSDL 2.0. The meaning of the acronym has changed from version 1.1 where the "D" stood for "Definition". Description The WSDL describes services as collections of network endpoints, or ports. The WSDL specification provides an XML format for documents for this purpose. The abstract definitions of ports and messages are separated from their concrete use or instance, allowing the reuse of the ...

Scope (programming)
In computer programming, the scope of a name binding (an association of a name to an entity, such as a variable) is the part of a program where the name binding is valid; that is, where the name can be used to refer to the entity. In other parts of the program, the name may refer to a different entity (it may have a different binding), or to nothing at all (it may be unbound). Scope helps prevent name collisions by allowing the same name to refer to different objects – as long as the names have separate scopes. The scope of a name binding is also known as the visibility of an entity, particularly in older or more technical literature—this is from the perspective of the referenced entity, not the referencing name. The term "scope" is also used to refer to the set of ''all'' name bindings that are valid within a part of a program or at a given point in a program, which is more correctly referred to as ''context'' or ''environment''. Strictly speaking and in practice for most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
