Bea is committed to promoting the compatibility of the entire application infrastructure through open standar

Service-Oriented Architecture (service-oriented Architecture,soa) is a component model that links different functional units (called services) of an application through well-defined interfaces and contracts between these services. Interfaces are defined in a neutral way, and should be independent of the hardware platform, operating system, and programming language that implements the service. This allows services built on a variety of such systems to

Depending on the SOA service, the definition of an SOA strategy varies from business operations, service level management, control deployment, to security, and so on. In general, SOA policy Management can add value from two perspectives: does it allow SOA based services to be made faster according to business changes?

Service-oriented architectures (SOA) and service-oriented integration (SOI) are widely used, and there is a need to become increasingly visible: business needs to integrate systems and allow consumers to access services using standards-based methods. SOA is an architectural paradigm. In this architecture, reusable business logic manifests itself as a set of services that contain standards-based, well-define

The first task to be done for integration using SOA is to use SSO or single sign-on to achieve unified login. 　　Bi Internet (chinabyte) January 07 column (zhuzhen)As a service-oriented architecture, the greatest value of SOA lies in the integration of multiple systems. The essence of integration lies in the integration of the data involved in the system. This must involve the integration of databases. If th

, the service-oriented architecture can be seen as the next revolutionary step in application architecture development, a revolution in replacing a single, tightly coupled application with modular and loosely coupled applications. SOA uses a modular approach, in which each combined or virtual application is composed of many different isolated services from independent applications. Services can be stored anywhere on the network. They can be found and

In the previous article, we introduced SOA and unified communication, including its overall concept and traffic business. Now we will continue to explain SOA and Unified Communication. First, let's review the four methods of SOA in speech. Then, we will introduce the situation of some products and vendors. Four Methods of hybrid speech and

What is SOA?If a company has a large number of applications that are used by staff in different departments who assume different responsibilities, then the service-oriented architecture (oriented Architecture,soa) is appropriate for use. These applications can share functionality, but the combination of features, user interface details, and ease-of-use requirements are different. Like many enterprise archit

Part-1 "Brief Introduction" 1. through the introduction of Service Oriented Architecture (SOA), Enterprise Service Bus (ESB), adapter (Adapter) and component-oriented technology, try to build a unified business process Service platform to realize process-oriented service integration. 2. The focus of traditional banking informatization is basically the construction and transformation of a single business system, with many internal systems and no use of

jquery calls the SOA architecture of WCF, applying a three-tier architecture to the SOA architectureAfter 3 days of study, I think we should have a preliminary understanding of the SOA architecture, in fact, SOA and the three-tier architecture does not conflict, but the three-tier architecture of the upgraded version.T

For example, if the X system knows the material code, needs to read the material information from the EBS system, or if the X system wants to synchronize its personnel information to EBS, you may need to use the Oracle EBS Integrated SOA Gateway for this kind of integration problem.Integrated SOA Ga

Key Points of SOA implementation: 1. Order of SOA construction. Is it from top to bottom or from bottom to top? I personally tend to grasp the overall situation, because what is important in SOA is not technology, but business positioning. If you design services from the bottom up, you may do a lot of repetitive work, or rework when you actually use them. Suffi

Guidance:Service-Oriented Architecture) is a service-oriented architecture. This is the most frequently used word in a variety of technical journals in the past one or two years. Currently, many architecture designers and design developers simply equate SOA with Web Services, and think SOA is a kind of Implementation of Web Services. In essence, SOA represents a

Do you really need a mature SOA model? The consensus is that such a team needs good guidance when implementing SOA, who should control the team, the vendor, the consultant, or an independent third-party organization? This is where the difference lies. Because SOA is related to specific implementation Process It is very similar to the development of the e

The concept of roost SOA, like today's "cloud computing, Big Data," is being fired, and many companies are responding and claiming to embrace and implement SOA. In fact, there are two extremes in the industry: one is that because the descriptions of the various articles and books about SOA are often too abstract, together with the calls of major vendors,

In 2006, SAP released the enterprise-level SOA application product mysap ERP 2005. The most frequently asked question is: what are the characteristics of SAP enterprise-level SOA products? In fact, the answer is obvious. SAP is not a pure technical platform, but a business platform that carries a wide range of enterprise-level SOA applications. When talking about

Although service-oriented architecture or SOA is still new, many companies are increasingly recognizing the need to adopt an SOA approach as a way to execute solutions that meet business needs. A key step in adopting this approach is to build a portfolio of reusable services. SOA represents a fundamental shift in the way new applications are designed, developed,

I haven't come up with a proper title for a long time. This question seems to be a bit "title party", but it is also what I want to express: SCA is not a technical problem, just as a netizen posted a message to me, SCA has no technical knowledge! Yes. SCA is a service-oriented component model that provides service componentization. The goal is to create a new layer to separate applications from middleware in the business logic of the IT infrastructure. The following describes what

It has been a few years since I first heard of SOA. During this period, I have had various discussions with various people, and I am increasingly aware that this is not a concept that can be clearly defined, in the past, there were no words in the software industry that were likely to cause so many criticism and debate. I sometimes think that SOA really wants to talk about it in Zen, "saying it is nothing "

From: infoq Qiao Liang Is methodology and architecture mutually exclusive? Some people think that software development practices and architecture are not repeated. This may be true in other environments, but it is not true in this topic. On the one hand, agile methods (such as XP) directly focus on design, rather than specifically agreeing to the idea of doing a lot of design (bduf) in advance. On the other hand, most SOA teams primarily focus on
