According to Linda Rising's book pattern almanac, there are more than 70 known architecture models. This is only a lot of statistics, including a lot of patterns that are generally considered to be design patterns, such as bridge, facade, interpreter, mediator and other models are generally considered as design patterns, however, in many cases, it can also be used as an architecture model, so it is often us

then design the actual architecture, to ensure sufficient guidance and restrictions for development ...... this is in line with the laws that humans solve problems and is therefore widely used. # Reading Notes # ease of use, performance, scalability, continuous availability, robustness, security, scalability, reusability, portability, comprehensibility, and testability may all be software quality require

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

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

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

, 1 days 24 hours into 48 parts, every half an hour corresponding to a provincial administrative unit, through the administrative provisions of the customer group, improve the efficiency of the cluster. Repeat the process the next day, the time-limited table is announced in advance. In addition, the computer system can not use simple addition to calculate the bottleneck, a province pilot can use, does not mean that the server volume *40 can support the country at the same time. First of all,

to a structure or multiple structures of systems that compose software elements, external visibility of elements, and relationships between elements. The architecture cares about the public interface; The private details of the element--the details of the internal implementation--are not schemas. The goal of the Schema is to identify the requirements that affect the application structure. A good
