layer provides a unique protocol between the user interface and the other tiers, allowing you to focus on application logic. Application logic is part of the business logic that arises directly from the use case.On the server side, the service layer method that is executed, reasonably arranges the required logic, through the coordination domain model, the Special Application service, the workflow.Without a

. What is clearly defined is usually quite complicated. 10) Design an error handling policy. For a layered architecture, error processing costs a lot in terms of processing time and programming. One principle of error handling: Try to handle the problem at the underlying level. Even if it is to be processed by a higher level, it should be converted into a type of error that the higher level can understand. In addition, reduce the error types and me

from each other. No component spans more than one layer. The words in the brackets are not fully understood (It is better to put more service layers at the higher level than the lower layer. This is because developers do not have to learn the many nuances of their friends. They can even learn more during parallel development. The extended top layer is suitable for wider application areas, while the base layer remains slim. This phenomenon is also cal

This article transferred from: http://www.ibm.com/developerworks/cn/webservices/ws-sca/ This article introduces the basic concepts in the SCA programming model and illustrates some of its basic uses in a simple example, expecting to be a catalyst and laying the groundwork for the reader to understand SCA later. Overview The industry's major software vendors are aggressively promoting the concept of service oritented

What is "Object-Oriented architecture"? Today, I suddenly realized how to define it in words. When developing software projects, various functional objects will be categorized and named with a memorable name.Repeat the functional objects and nouns to generate an architecture of its own. In the domain layer of DDD (domain-driven design.1. The system has a us

Previous summary document Web service Search and execution engine (III)-System Design SchemeIt can be said that it is a physical structure of the system. Based on this structure, we design the following system architecture. 1System Function DiagramThe system function Diagram 1 is shown in.

business needs. The purpose of the CMDB construction is to satisfy the needs of the business, to ensure the continuous and efficient operation of the business, but in many cases, we just use the CMDB as a static configuration management library, not closely related to the business.If you want to put the business system on the path of agile operations, it is bound to the traditional CMDB make an innovation to realize the change of ideas and ideas.

The future software architecture requires a new development approach. Is your company ready for the job? by Jason Bloomberg Today's description of Web services (Web service) is primarily about integration. Companies that have come out of recession have taken the cost of integration down as an obvious goal. The use of open, standards-based, loosely coupled Web services technologies provides a less expensive

ASP. NET Web API and WCF both reflect the REST software architecture style. In REST, all data is regarded as resources, so it is also a resource-oriented architecture style. All resources can be uniquely identified by Uris. By performing HTTP operations on resources (GET/HEAD, POST, PUT, and DELETE), the resource's characterization status changes, that is, Repres
