Logic Centralization Pattern
Logic Centralization is a design pattern, applied within the service-orientation design paradigm, whose application aims to increase the reusability potential of agnostic logic Logic that does not belong to a specific business process and hence can be reused to automate multiple business processes by ensuring that services do not contain redundant agnostic logic and that any reusable logic should only be represented by a service that has the most suitable functional context.The type of the functionality provided by the service.Kanu TripathService Transaction Handling Without WS-AtomicTransactionOnline].Date accessed: 25 April 2010. Rationale As more and more services are developed, there is a constant risk that services with redundant functionality may be created. Although the application of the Service Normalization Pattern, Service Normalization design pattern does help to eliminate this redundancy, however, just having a set of normalized services on its own, does not guarantee ...

Design Pattern
A design pattern is the re-usable form of a solution to a design problem. The idea was introduced by the architect Christopher Alexander and has been adapted for various other disciplines, particularly software engineering. The " Gang of Four" book. Details An organized collection of design patterns that relate to a particular field is called a pattern language. This language gives a common terminology for discussing the situations designers are faced with. Documenting a pattern requires explaining why a particular situation causes problems, and how the components of the pattern relate to each other to give the solution. Christopher Alexander describes common design problems as arising from "conflicting forces"—such as the conflict between wanting a room to be sunny and wanting it not to overheat on summer afternoons. A pattern would not tell the designer how many windows to put in the room; instead, it would propose a set of values to guide the designer toward a decis ...

Service-orientation
Service-orientation is a design paradigm for computer software in the form of 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 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, different vendor SOA platforms have used different defin ...

Design Paradigm
A design is a plan or specification for the construction of an object or system or for the implementation of an activity or process or the result of that plan or specification in the form of a prototype, product, or process. The verb ''to design'' expresses the process of developing a design. In some cases, the direct construction of an object without an explicit prior plan (such as in craftwork, some engineering, coding, and graphic design) may also be considered to be a design activity. The design usually has to satisfy certain goals and constraints; may take into account aesthetic, functional, economic, or socio-political considerations; and is expected to interact with a certain environment. Typical examples of designs include architectural and engineering drawings, circuit diagrams, sewing patterns and less tangible artefacts such as business process models. Designing People who produce designs are called '' designers''. The term 'designer' generally refers to someone wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SOA Governance
SOA Governance is a set of processes used for activities related to exercising control over services in a service-oriented architecture (SOA). One viewpoint, from IBM and others, is that SOA governance is an extension (subset) of IT governance which itself is an extension of corporate governance. The implicit assumption in this view is that services created using SOA are just one more type of IT asset in need of governance, with the corollary that SOA governance does not apply to IT assets that are "not SOA". A contrasting viewpoint, expressed by blogger Dave Oliver and others, is that service orientation provides a broad organising principle for all aspects of IT in an organisation — including IT governance. Hence SOA governance is nothing but IT governance informed by SOA principles. The focus of SOA governance is on those resources to deliver value to the business. SOA systems require IT support processes as well as organizational processes that will also involve the busine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Service Reusability Principle
The service reusability principle is a design principle, applied within the service-orientation design paradigm, to create services that can be reused across a business.Thomas Erl, Herbjörn WilhelmseSOA Pattern of the Week (#4): Service NormalizationOnline]. Date accessed: 14 April 2010. These reusable services are designed so that their solution logic is independent of any particular business process or technology. Purpose Service reusability is typically measured by how much extra functionality a service contains that could be reused in future, and how much of the service’s functionality goes beyond the current requirements. This encourages services that contain extra capabilities built around possible future service usage scenarios. However, little is done in designing the service logic in a manner that it could be reused to automate multiple business processes. This results in more focus on equipping services with extra functionality than concentrating on making the core se ... [...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 composi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
