Standardized Service Contract
The standardized service contract is a software design principle applied within the service-orientation design paradigm to guarantee that service contracts within a service inventory (enterprise or domain) adhere to the same set of design standards. This facilitates standardized service contracts across the service inventory.Michael PouliEvolution of principles of Service Orientation: Service Contract, part 2.Date accessed: 12 April 2010. Purpose The agility promised by a service-oriented architecture (SOA) is usually measured in terms of the reusability level of its contained services. However, this reusability relates directly to the way the service contract defines service capabilities. A service built on a potentially reusable functional contextThe boundary of the service, i.e., the type of functions the service provides but with a contract that does not convey this reusability correctly does not achieve its reusability potential. Within service-oriented solutions, a service c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Software
Software consists of computer programs that instruct the Execution (computing), execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware. The introduction of high-level programming languages in 1958 allowed for more human-readable instructions, making software development easier and more portable across different computer architectures. Software in a programming language is run through a compiler or Interpreter (computing), interpreter to execution (computing), execute on the architecture's hardware. Over time, software has become complex, owing to developments in Computer network, networking, operating systems, and databases. Software can generally be categorized into two main types: # operating systems, which manage hardware resources and provide services for applicat ...

Service-orientation
Service-orientation is a design paradigm for computer software in the form of Service (Systems Architecture), services. The principles of service-oriented design stress the separation of concerns in the software. Applying service-orientation results in units of software partitioned into discrete, autonomous, and network-accessible units, each designed to solve an individual concern. These units qualify as services. History of service-orientation principles and tenets Service-orientation has received a lot of attention since 2003 due to the benefits it promises. These include increased return on investment, organisational agility and interoperability as well as a better alignment between business and Information technology, IT. It builds heavily on earlier design paradigms and enhances them with standardisation, loose coupling and business involvement. The paradigm lost momentum in 2009; since 2014, renewed interest can be observed under the Microservices moniker. In technology, dif ...

Design Paradigm
The concept of design paradigms derives from the rather ambiguous idea of paradigm originating in the sociology of science, which carries at least two main meanings: * As models, archetypes, or quintessential examples of solutions to problems. A 'paradigmatic design' in this sense, refers to a design solution that is considered by a community as being successful and influential. Usually success is associated to market share or some other measure of popularity, but this need not be the case. For instance, the eMate and other Apple Newton devices can be considered as paradigmatic because of their influence in subsequent designs, despite their commercial failure. * As sociological paradigms, a design paradigm is the constellation of beliefs, rules, knowledge, etc. that is valid for a particular design community. Here a paradigm is not a particular solution, but rather the underlying system of ideas that causes a range of solutions to be 'normal' or 'obvious'. A current example is the ...

Service-oriented Architecture
In software engineering, service-oriented architecture (SOA) is an architectural style that focuses on discrete services instead of a monolithic design. SOA is a good choice for system integration. By consequence, it is also applied in the field of software design where services are provided to the other components by application components, through a communication protocol over a network. A service is a discrete unit of functionality that can be accessed remotely and acted upon and updated independently, such as retrieving a credit card statement online. SOA is also intended to be independent of vendors, products and technologies. Service orientation is a way of thinking in terms of services and service-based development and the outcomes of services. A service has four properties according to one of many definitions of SOA: # It logically represents a repeatable business activity with a specified outcome. # It is self-contained. # It is a black box for its consumers, meaning ...

XML Schema
An XML schema is a description of a type of XML document, typically expressed in terms of constraints on the structure and content of documents of that type, above and beyond the basic syntactical constraints imposed by XML itself. These constraints are generally expressed using some combination of grammatical rules governing the order of elements, Boolean predicates that the content must satisfy, data types governing the content of elements and attributes, and more specialized rules such as uniqueness and referential integrity constraints. There are languages developed specifically to express XML schemas. The document type definition (DTD) language, which is native to the XML specification, is a schema language that is of relatively limited capability, but that also has other uses in XML aside from the expression of schemas. Two more expressive XML schema languages in widespread use are XML Schema (with a capital ''S'') and RELAX NG. The mechanism for associating an XML do ...

Web Service
A web service (WS) is either: * a service offered by an electronic device to another electronic device, communicating with each other via the Internet, or * a server running on a computer device, listening for requests at a particular port over a network, serving web documents (HTML, JSON, XML, images). In a web service, a web technology such as HTTP is used for transferring machine-readable file formats such as XML and JSON. In practice, a web service commonly provides an object-oriented web-based interface to a database server, utilized for example by another web server, or by a mobile app, that provides a user interface to the end-user. Many organizations that provide data in formatted HTML pages will also provide that data on their server as XML or JSON, often through a Web service to allow syndication. Another application offered to the end-user may be a mashup, where a Web server consumes several Web services at different machines and compiles the content into one user int ...

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 like 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 Communication endpoint, endpoints, or Port (computer networking), ports. The WSDL specification provides an XML File format, format for documents for this purpose. The abstract definitions of ports and messages are separated from their conc ...
