An excellent and mature software R D organization will inevitably collect various software design knowledge and experience in daily development, establish and maintain a software reuse Knowledge Base Based on architecture and design patterns, and actively and frequently use various
we ensure that the entire tall building will not fall down? What components are required for each application field (hospitals, factories, hotels )? What are the practical, beautiful, powerful, and cost-effective component frameworks that allow the built buildings (that is, the architecture) to better meet user needs? Just as civil engineering has entered modern architecture,
frameworks, and APIs, which is the most common form of reuse.

In DOTNET Enterprise Architecture Application practices a few days ago-the history and development of enterprise management software architecture (Computing) (I, this section describes the host-terminal structure, client-server structure, and browser-server structure in the release of enterprise management software
Architecture Analysis: The architecture analysis work mainly considers how a software system should be organized from a macro perspective. Usually, in the framework of the analysis work, we need to identify some strategic design guidelines, principles and basic patterns. Under their guidance, we can analyze the macro structure of
Today, my colleague asked me what is the use of web service in the system? What is the difference between it and the general direct writing on the client? What are the advantages? It is really interesting to answer this question. Since I have asked this question, it means that there are some preconditions for not reaching an agreement. It is easy to explain the technology itself. Therefore, we should first clarify the background of recommending the use of the SOA
To develop a user-satisfied software is not easy, the software architect must fully grasp the various requirements, balance the need for potential contradictions between the needs of different categories to meet. From the understanding of the complexity of requirements, this paper demonstrates how to design the architecture of different requirements through RUP's
Building a model for service-oriented architecture (service-oriented architecture) using Rational Software Architect, part 1th: Case studies, tools, and business viewsThis tutorial introduces the use of IBM Rational Software Architect to establish a service-oriented architecture
architecture? Just as the software has its own goals, what are the goals of architecture design? In general, the software architecture design should achieve the following goals: · Reliability ). Software systems are extremely imp

. Implement abstract methods defined at the abstraction layer and Interface Layer 2.Define the process for calling the framework 3. If the underlying layer uses a third-party frameworkAdaptation and decoration layer, Refer to adapter mode and decorator Mode The specific implementation layer uses common classes for implementation,It mainly implements specific functions, but does not participate in the framework call process.. The layer-4 structure is a scalable, robust design, interface layer d
structure behind various functions. If the definition function is equivalent to taking a photo, Domain Modeling is equivalent to "pivoting", paying more attention to the internal structure of the problem domain, this is equivalent to a certain abstraction of the problematic domain. A good domain model not only supports existing functions, but also supports new requirements in the future to a certain extent, excellent scalability. ◆ Provide communicat

scalability and maintainability of the system, we should not over-design it. Sometimes you may not be able to determine which designs are overly-designed. At this time, you can ask your PM to let him stand at the height of the entire project to help you make a decision. 3. architecture is neither a framework nor a combination of several frameworks or technologies. The framework itself is also structured. The framework is generally intended for semi-f
, synthesis, assembly and testing of components. Architecture Evolution. If the user needs have changed, we need to modify and optimize the software architecture accordingly to adapt to the new changing software requirements. The above 6 sub processes are the general method
Understanding rest and understanding the future of the Web For web development, the Chinese version of the landmark Fielding's PhD thesis on rest has been officially released. Dr. Roy Thomas Fielding is a major designer for Web architecture standards such as HTTP, Uri, and so on. For the first time in his doctoral dissertation in 2000, he gave a systematic and comprehensive exposition of rest's architectural style and design ideas. This paper is a v

The Research and Practice of the software architecture style promotes the reuse of the design. Some proven solutions can also be used reliably to solve new problems.

) modeArchitectural patterns are often divided into the following categories:A), from MUD to structure type. Help architects divide the system to avoid forming an ocean of objects (a sea of objects). Includes layers (layered) mode, Blackboard (blackboard) mode, pipes/filters (pipe/filter) mode, and so on.II), dispersion system (distributed systems) type. Provides a complete architectural design for decentralized systems, including broker-like (mediation) mode.III), Human-machine interaction (Int
, the fonts and other possible options are best not absolute, they should be set in a configuration file, and included in each page. The style of the site should also be independent-so you do not have to copy and paste every page of the work, I usually put these HTML in a function, and then can be called when needed. For database passwords, database connections, and so on, it is also placed in the database abstraction layer. 4. Object-oriented/function We can split the process processing into di
