Hierarchy in Software System Architecture About the layered structureAs we all know, the classic three-tier structure includes the data access layer, business logic layer, and presentation layer. Of course, if you continue to expand, it can also be divided into four layers, five layers ...... I believe that many people have used it and many people have written it. But why is it so difficult for some people

along each pipeline 3, decide how to implement each pipeline connection 4, design and implement filter 5, design error handling 6, set up a processing lineResolved example--TCP/IP protocol known to use: Unix pipelining tasks: Program compilation, document creation effect-advantages: Not necessarily intermediate files, filter exchange/reorganization flexibility, reuse, rapid prototyping, parallel processing inefficient: Sharing state information expensive/inflexible, parallel processing efficien

Software architecture is more important than writing code. The architecture design of the software system requires how the components of the design system are divided, how the components interact, and the logical, physical, and systematic planning of the system. The initial architectural design also determines the suit

b/S architecture system, will use the following basic software architecture:Data access layer: To achieve access to data functions, such as adding, deleting, modifying, querying data.Business Logic layer: realize the specific logic function of the business, such as student's entrance, drop-out, achievement management, etc.Page display layer: Display the business functions on the browser, such as pagination

Types of software EvolutionSoftware evolution is like biological evolution, some mutations are beneficial to species, and some are harmful.The key to differentiate the type of software evolution is whether the quality of the program is increased or decreased in this process. The second is that this evolution is the result of the process of the construction of the show sea, or the maintenance process of modi

data center uses NAS and fc san. • The parallel computing of servers mostly uses Infiniband and Ethernet. • Different servers have heterogeneous operating systems and upper-layer software, and different interfaces and data formats.

Successful software architecture design is of high quality, and the time and technical decision-making can meet specific requirements.The sending method must have the following qualities: Good modularization: Each module has clear responsibilities, loose coupling between modules, high cohesion in the module, and reasonable information hiding. Adapt to functional requirements and technical changes: in

Memory is an important module in the Integrated Design of SOC (system on chip, on-chip system) and a significant proportion of cost in SOC. The software and hardware design of memory management is an important part of SOC Software Architecture Design. architects must balance costs and efficiency to ensure the performance of the entire system while saving memory.

The purpose of software architecture design is simply to break down the software system and reduce the complexity of software system development under the premise of keeping the software internal connection, and the basic methods of decomposition

Single taskProgramTypical Architecture (1) starting from the specified address when the CPU is reset; (2) Jump to assemblyCodeExecute at startup; (3) Jump to the main program of the user owner and execute it in main: A. testing various hardware devices; B. initialize each software module; C. Enter an infinite loop and call the processing functions of each module. The user's main program and

).ActiveMQACTIVEMQ is a sub-project under Apache. Similar to ZEROMQ, it is able to implement queues with agent and peer-to-peer technology. It is also similar to RABBITMQ, where a small amount of code makes it possible to implement high-level scenarios efficiently.Kafka/jafkaKafka is a sub-project under Apache and is a high-performance cross-language distributed publish/Subscribe Message Queuing system, and Jafka is hatched on Kafka, an upgraded version of Kafka. Has the following characteristic

1, b/s structure:Through the C language or Java can be implemented, using the B/s architecture of software, start, open applications and the same effect as native software.(The normal browser opens the application page has the Address bar, the menu bar and the tab bar, but through the configuration can close these windows, make B/s application more like a

PerformanceFor users, programmers are delivering software, providing a refreshing user interface, and avoiding system crashes is often more important than the performance of the program.There is a loose relationship between performance and code speed. This kind of work is a bit forgotten how if you're just focusing on how fast your code is running. In particular, be careful about giving up other functional areas to make your code run faster. If the sp
