J2EE B S SOA which is the architecture architecture and what is the difference

SOA architecture refers to service-oriented architecture, which is a component model, a coarse-grained, open, and loosely coupled service structure, which requires software products to be developed in layers according to relevant standards or protocols during the development process. Through this hierarchical design or architecture system, software products can become more flexible and flexible, and as complementary and compatible with third-party software products as possible, so as to achieve rapid expansion to meet or respond to the diversification and variability of market or customer needs.

It connects the different functional units of an application through well-defined interfaces and contracts between these services. The interface is defined in a wheel-neutral manner, and should be independent of the hardware platform, operating system, and programming language in which the service is implemented.

The SOA architecture brings business-driven IT, that is, business-driven and business are more closely linked. Model the company's business on the basis of coarse-grained business services, which can produce a concise view of the business and systems; The IT system based on business services is more flexible, easier to revisit, and faster to respond to changes in enterprise business needs. Based on business services, it provides a better relationship between the business service model and related IT services"Traceability"。

SOA architecture stands for Service Oriented Architecture.

Service-oriented architecture is a component model that connects the different functional units of an application, called services, through well-defined interfaces and contracts between those services.

The interface is defined in a neutral way, and it should be independent of the hardware platform, operating system, and programming language that implements the service. This allows services built into a variety of such systems to interact in a unified and generic way.

SOA is the abbreviation of the three first words of service-oriented architecture in English, which is translated into Chinese: Service Oriented Architecture (SOA) II. The origin or historical reasons for the emergence of SOA architecture Traditional enterprise (OA) application software products, such as MRP, ERP, OA systems, etc., are tightly coupled, closed, and self-contained in terms of design or architecture, and belong to products that are completed at one time.

It is difficult for such a product to adapt or respond quickly to the flexible needs of the market or customers, as well as subsequent expansion. Under such a market and customer needs, a new concept of design or architecture of software products has been born, Service Oriented Architecture (SOA Architecture) III. Definition or characteristics of SOA architecture.

It is a coarse-grained, open, and loosely coupled service structure, which requires software products to be developed in layers according to relevant standards or protocols during the development process. Through this hierarchical design into an architecture break, the software production can be more flexible and flexible, and as far as possible complementary and compatible with third-party software products, so as to achieve rapid expansion, to meet or meet the diversification and variability of market or customer needs. Four.

Fabric layering of SOA architecture BEA Workshop for WebLogic Platform (or WebLogic Workshop for short) software development tool is currently the only recognized software product development tool for SOA architecture in the industry. Users can develop software products under SOA architecture without paying attention to the standard requirements or protocol requirements of SOA architecture, and only need to write components that implement business requirements.

There are four layers of component writing requirements: persistence layer, logic layer, execution layer, and user interface layer. If the software system is a distributed system, you need to write Layer 5:

Web Services (Service Layer, note not: Web Server server) five. What is the purpose of SOA architecture and what is its practical significance?

The significance of designing a software product as an SOA architecture and purpose or reality is as follows: 1Preserve or protect the original software system (data) of the enterprise, realize the seamless integration of software data, and avoid the original investment of the enterprise and the need for repeated data entry.

2.As a result, the implementation and promotion period of software products can be shortened. 3.

This can be done during the implementation of the promotion. Adjust quickly to best meet the needs of your customers. 4.

When the customer's application business changes and the investment and transformation must be carried out, the product can be newly expanded rapidly or directly third-force equipment (software and hardware efficiency. 5.In this way, the rigidity of the product itself is avoided, and it becomes a legacy system that saves use.

SOA itself is a component model that can be distributed, assembled, and used over a network of loosely coupled, coarse-grained application components based on requirements. The service layer is the foundation of SOA and can be called directly by the application, effectively controlling the artificial dependencies of the system that interact with the software.

SOA will help software engineers understand the development and deployment of various components of enterprise architecture at a new level, and it will help enterprise system architects to architect entire business systems faster, more reliable, and more reusable. Compared with the past, systems with SOA architecture can face the rapid changes in business more calmly.

Based on the SOA architecture system, Founder Feihong Intelligent Information Platform is an efficient, powerful and open development tool for enterprise application development, combined with a variety of implementation tools such as data modeling, business modeling, visual process engine, and dynamic form design. Its flexible characteristics ensure that the system developed based on the platform can be used. The NET platform and the J2EE platform are seamlessly switched between operation.

There is a detailed introduction in the encyclopedia...

IBM developed a platform architecture for complex systems in the enterprise 20 years ago.

The three-layer architecture (presentation layer, business logic layer, and data access layer) is now used in general software projects, including applications, mid-residual interware, and data servers. It is now the mainstream architecture of general software projects.

SOA (ServiceOriented) is a service-oriented architecture, which is mainly a software development idea. Develop and package the corresponding programs according to the needs of different objects, and independently envy the hardware platform, operating system and programming language that implements the service, which can effectively save investment and greatly improve the scalability of the software.
