just enough software architecture

wrong direction, if Google chose this centralized supercomputing mode, then perhaps there is no ordinary people can enjoy the convenient and inexpensive search service, using search has become my 8-year-old son basic tools, he learned Chinese characters, They will use these characters to find the games that they want to play in Google, and the search and Chinese characters have been incorporated into the blood of our next generation, thanks to the shift in computational thinking: Distributed co

Five years of work, management and design work have been done, the next stage of the main work in the framework design, team technical training, recently met to read a few books, such as "appropriate software architecture", something more, pick some important notes below.1. Shall not be allowed to do so;A good fit for architecture design or development, and is co

Mode System Patterns are not isolated-they are mutually dependent, and the pattern system binds their composition patterns together. A Software Architecture Model System is a collection of software architecture models. It includes guidance on implementation, combination, and actual use of models in

PrefaceIntroduced by EMMC Basic Technology 1:MMC Introduction of MMC, SD, Sdio, the introduction of these three technologies are originated from MMC technology, there are many similarities, so the Linux kernel Unified Use MMC framework to manage all the devices related to these three technologies.This article will be based on EMMC basic technology 1:MMC Introduction to the MMC technology, learning the Linux kernel MMC framework

I have seen many growing enterprises. With the expansion of business and the increase of data streams, their software is increasingly exposed to growth bottlenecks, then we will try out the architecture in a hurry and try our best. There are too many such enterprises in China, and I am sorry to say a lot. No matter what software is exposed to growth bottlenecks

1) physical architectureThe purpose of the physical architecture is to determine the topological structure of physical nodes and physical nodes. The physical nodes include servers, PCs, dedicated servers, software installation, deployment, and writing, and system software selection; the Topological Structure defines the relationship between physical nodes. 2) Op

located and execute the Python ez_setup.py on the command line The scripts directory will be generated in the Python installation directory, with Easy_install.exe Add the script directory to the environment variable path. 2. Installing the SQLAlchemy module CMD command line, Run command: Easy_install sqlalchemy Specific code shows: For more tutorials, you are welcome to focus on today's headlines-making full-stack siege lions. Talk about learning together.

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

c/S structure, that is, client/server (client/server) structure, is well-known software system architecture, through the rational allocation of tasks to the client side and server side, reduce the communication overhead of the system, can make full use of the advantages of both ends of the hardware environment. Early software systems used this as the preferred de

Abstract: Lao Tzu's philosophy, morality, software philosophy, and software reference: top ten programming rules for eliminating human wolf software in sequence SAGE:Kong de's only path is from. The path is "thing", but "nothing. Which has an image. There is something in it. Some of them are excellent. Its essence is very real, and there is a letter in it. Since

notification mechanism to achieve synchronization.4) Synchronization is flexible, you can synchronize only a subset of the data in the database.5) daemon is implemented in Perl language, and is synchronized by Pl/pgsql and Pl/perlu functions.4, Pl/proxyThe software, features and features of the PG database for horizontal splitting are as follows:1) The application sends the request to the horizontal split middleware, which sends SQL to the underlying

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

Linux operating system High-Performance cluster-Software Architecture-Linux general technology-Linux programming and kernel information, the following is a detailed description. This article is the third part of the High-Performance cluster series. In this article, I take IBM eServer Cluster 1300 as an example to introduce the hardware and network architecture an

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

We talked about the underlying core OS in the iOS software architecture, and the core service layer of the iOS system, on top of the kernel OS layer, consists of two parts: Core service libraries and advanced features based on core services. This article makes a detailed explanation of these two functions.First, the core services layer contains the following libraries:1. Address Book FrameworkFor Address Bo

Complex software must have a clear and reasonable architecture, otherwise it cannot be developed and maintained.MVC (Model-view-controller) is one of the most common software architectures and is widely used in the industry. It's easy to understand, but it's not easy to tell the difference between the derived MVP and the MVVM

services in the form of a report server. At this time, this Web report tool works in a way similar to products such as crystal report, it has the same advantages and disadvantages as an independent server (the independent server here refers to the logic, and can still be physically installed together with other servers ). For Java applications, the report software can be embedded into the J2EE application archite
