Service-Oriented Architecture and Legacy Systems

IEEE Software offers solid, peer-reviewed information about today's strategic technology issues. To meet the challenges of running reliable, flexible enterprises, IT managers and technical leads rely on IT Pro for state-of-the-art solutions. Enterprise systems are quickly evolving from monolithic silos to distributed applications with service-oriented exible usage schemes. To keep up, IT organizations must adapt their legacy systems to meet changing business challenges almost in real time, with no second chances. Service-oriented architectures (SOAs) have evolved to exibly operate and federate business processes and underlying systems. Today’s business must be able to flexibly and quickly adapt to market needs, but even minor changes to processes can involve rework in multiple IT systems that were originally designed as application silos.

For example, if you are a service provider, service enablement enables you to dynamically provision new Web services and meter the use of those services. COLLECTIONS Service Oriented Architecture - Shaw Systems Associates, Inc. The collections products provide a clear positive advantage because they are built on a service-oriented architecture (SOA) where business functions are exposed.

SOA reduces integration expenses, increases business agility, and decreases business risk. Designed around common business objects, services are understandable by business as well as technical staff members. Under this architecture, Shaw has developed a series of accounting solutions for the market's leading application environments. Service Oriented Architecture. Service-orientation. Service-orientation has received a lot of attention since 2005 [4] 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.[5]

Loose coupling in SOA

Architectural pattern. Definition[edit] Even though an architectural pattern conveys an image of a system, it is not an architecture.

Architectural pattern

An architectural pattern is a concept that solves and delineates some essential cohesive elements of a software architecture. Countless different architectures may implement the same pattern and share the related characteristics. Patterns are often defined as "strictly described and commonly available".[2][3] For example, the layered architecture is a call-and-return style because it defines an overall style to interact. When it is strictly described and commonly available, it is a pattern. Paradigme. Un article de Wikipédia, l'encyclopédie libre. Universum, C. Flammarion, gravure sur bois, Paris 1888.

Design pattern. A design pattern in architecture and computer science is a formal way of documenting a solution to a design problem in a particular field of expertise.

Design pattern

The idea was introduced by the architect Christopher Alexander in the field of architecture[1] and has been adapted for various other disciplines, including computer science.[2] An organized collection of design patterns that relate to a particular field is called a pattern language. The elements of this language are entities called patterns. Each pattern describes a problem that occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice. — Christopher Alexander[1] The usefulness of speaking of patterns is to have a common terminology for discussing the situations designers already see over and over.

Service-orientation. SOA (Service Oriented Architecture) Definition. Stands for "Service Oriented Architecture.

SOA (Service Oriented Architecture) Definition

" When businesses grow, they often add new products and services. While these additions may help make the business larger, it is often difficult to implement them in an efficient manner. The goal of SOA is to make it easy for businesses to grow and add new services. Separation of concerns. The value of separation of concerns is simplifying development and maintenance of computer programs.

Separation of concerns

When concerns are well-separated, individual sections can be reused, as well as developed and updated independently. Of special value is the ability to later improve or modify one section of code without having to know the details of other sections, and without having to make corresponding changes to those sections. Implementation[edit] Separation of concerns is an important design principle in many other areas as well, such as urban planning, architecture and information design.[5] The goal is to more effectively understand, design, and manage complex interdependent systems, so that functions can be reused, optimized independently of other functions, and insulated from the potential failure of other functions.

Origin[edit] The term separation of concerns was probably coined by Edsger W. Let me try to explain to you, what to my taste is characteristic for all intelligent thinking. Modular programming. "Code Factoring" redirects here.

Modular programming

It is not to be confused with code refactoring. Separation of concerns. Software architecture. Software architecture is the high level structure of a software system, the discipline of creating such structures, and the documentation of these structures.

Software architecture

It is the set of structures needed to reason about the software system, and comprises the software elements, the relations between them, and the properties of both elements and relations.[1] The architecture of a software system is a metaphor, analogous to the architecture of a building.[2] Software architecture choices include specific structural options from possibilities in the design of software. For example, the systems that controlled the space shuttle launch vehicle have the requirement of being very fast, and very reliable, in principle. Therefore an appropriate real-time computing language would be chosen. Similarly, multiple redundant independently produced copies of a program running on independent hardware and cross-checking results would be a software system architecture choice to satisfy the need for reliability.

Pour les articles homonymes, voir BPM. Le Business Process Management (BPM), ou Gestion des Processus Métiers[1], permet d’avoir une vue d’ensemble de processus métiers[2] de l’organisation et de leurs interactions pour les optimiser et les automatiser autant que possible.

Pour ce faire, il faut analyser le fonctionnement réel de l'entreprise afin de le modéliser informatiquement, par exemple avec le formalisme BPMN et les outils associés. Complex Event Processing and SOA: a 'beautiful thing'? The drums keep beating louder for the impending marriage of SOA with Event Driven Architecture and Complex Event Processing. This is top of the news for many analysts, and something IBM, Oracle, and other vendors are positioning future offerings around. Is this the year when organizations will start linking SOA efforts closely to real-time processes? Are we ready to link SOA with real-time processing? IBM WebSphere CTO Jerry Cuomo recently said that he sees the SOA-EDA-CEP marriage as one of the most pronounced trends to watch in 2008. As Cuomo explained in a recent interview with SearchSOA's Rich Seeley: "I really believe [event processing is] the next big thing in SOA.... we're taking it very seriously.

" CEP and SOA: Six Letters Are Better than Three. Service-Oriented Architecture (SOA) If you establish more data integration by using ODS and MDM data stores, you also need a messaging, or communication, architecture to enable systems that weren’t built to communicate with each other to do so. Enter the concept of service-oriented architectures, or SOAs. SOA - Architecture Orientée Service. Component-based software engineering. An example of two components expressed in UML 2.0. The checkout component, responsible for facilitating the customer's order, requires the card processing component to charge the customer's credit/debit card (functionality that the latter provides).

Component-based software engineering (CBSE) (also known as component-based development (CBD)) is a branch of software engineering that emphasizes the separation of concerns in respect of the wide-ranging functionality available throughout a given software system. It is a reuse-based approach to defining, implementing and composing loosely coupled independent components into systems. This practice aims to bring about an equally wide-ranging degree of benefits in both the short-term and the long-term for the software itself and for organizations that sponsor such software.
