not related to the technology, but to the specific business, a platform can run enterprise management system, campus management system or hospital management system.5) using B/S and C/s structure combinedb/S structure with the features of free installation, C/S has a higher security, do not install inaccessible. As long as the Internet, you can through the browser to B/s structure system access, enter the account number and password any machine (such
requirements distribution in the startup phase, memory requirements during OS boot initialization, and so on. These are not the specifications of the product, it is also the architectural designer to consider. Typically, the memory obtained in 6 is evaluated again for minor adjustments. Please focus on the SOC Embedded software Architecture Design (Controller S
The design pattern mentioned here is the pattern in software design, mainly refers to the object-oriented software design. Compliance with the design model can effectively improve the maintainability and reusability of
analysis, it is possible to release a runable and error-free product without performing any usability tests, however, the "user-centered" design principle will be included in the design process, and a product that has been improved in many aspects will be created.The best reason for usability testing is to reduce the number of technical support service calls tha
, and it is no longer popular 16.DAO Factory modeThe user is interested only in the product being created, and many of the extra work done before the creation of the product is encapsulated into the subclass of the factory interface, but not the constructor of the specific product class, which is used implicitly Change mode only and database connection function, do not realize the function of accessing data The difference between 17.J2EE design patter
speaking, the architecture of software system gives the information such as the organization of software system, the structure element of composing system, the choice of its interface, the behavior of system and the architecture style. In other words, it not only cares about the functional requirements of the structure and behavior of the system, but also the non-functional requirements such as the perform
not simply create a chromatic version and write a bunch of specs, but began to rethink it from some of the most basic issues. 3 years ago, when Duarte launched Android 4.0, he asked the world: "Does the machine have a soul?" 3 years later, Matias, after releasing material design and Android L, asked, "How is the software formed?" How is the software formed? Ma
I personally think that there are too many concepts in this book. The architecture and development of software are not a combination of concepts. Just use the appropriate words to describe some empirical things. The so-called risk-driven model selects the appropriate design strength based on the project situation to avoid over-design. For complex
[GOF95] is the first book on the software model and the most popular book on OO Design theory. Therefore, some people often use Design Pattern) the term "1" refers to any kind of pattern that directly processes the architecture, design, and program implementation of the software
[Gof95] is the first book on the software model and the most popular book on OO design theory. Therefore, some people often use design pattern) the term refers to the architecture, design, and, Program Any type of implementation mode. Others stress that three different layers of patterns should be divided:
Chapter 5 is finally available-FPGA-based c2mif software design and VGA application I. Overview of the MIF File For a long time, do you want to talk about the design and application of the MIF file? Bingo cannot decide on his own. I have written so many, and I am a little tired. Finally, I bit my teeth and wrote it, because no one has ever written it, so I wan

If the previous discussion on the reliability of medical information still leaves some commercial taste (although it is nominal to return to the technology, it still involves some business issues); then, this article intends to continue with the technical aspects, discuss the design model, and: -To discuss the design patterns in the integration field, we should start from the
matured and understood and accepted by computer, and people began to consider the problem of object-oriented development. Until now, Object-oriented has become a very popular programming method, as well as the architecture of software design. The object-oriented approach has three main objectives: reusability, flexibility and extensibility, emphasizing objects ' abstraction, encapsulation, inheritance, an
To sum up, we can establish a systematic software architecture design process. Typical Software Architecture DesignShows the process.I. Concept of Business ArchitectureBefore building a software architecture, the architect should carefully study the following issues:Why is the system built for the purpose?What are the

-14, with little meaning.7. Do not pay attention to the details:The preliminary design should not pay attention to details. For example1. Only the object name is identified for each object, and its properties and methods are not recognized.2. "Current Account Pin user interface", which may be a dialog box, Web interface, character terminal interface, but the robust diagram does not care about these details.3. Are entity objects such as "customer data"
://en.wikipedia.org/wiki/Command-query_separationYou Ain ' t gonna need It (YAGNI)This principle, in short, is to consider and design only the necessary functions to avoid over-design. Just implement the features you currently need, and you can add them later when you need more features. Do not add complexity if it is not necessary. Software developm

But it can also be the hardest to apply (because to do so, we need to do a lot of work on generic design, which is not an easy task). It means tha
