1. What is architecture?The common components abstracted from multiple products are organically linked to form an architecture.At present, we abstract the commonalities of technology, called sea.The sea architecture describes the elements contained in a software and the relationship between the elements to form a skeleton. On this basis, multiple products can be
-aggrandizing accoun-tants. It's about multipliers, and the effect they can has.Suppose you has a decision to make about a particular feature. You can do it with the easy-to-a day, or the hard-on-the-week. Which should do it? Suppose that's the easy-to-do makes four new fields required, whereas doing it's the hard-to-do makes the program smart enough to Handle incomplete data. Which should do it???? Required fields seem innocuous, but they is always a imposition of your on users. They force user
Non-functional requirements of information management systems in large enterprises and enterprises Technical Reference of software architecture Jin song Management information systems generally have three typical architecture models.The main non-functional indicators are compared as follows: Figure: three typical
What is the software architecture? How do you understand the software architecture? Second School of view: composition school: the architecture of the software system describes the interaction between the computing component and t
Before I take this course, the code that I write in my mind and practice is still in a small project, and perhaps a simple project can solve most of the problems. But after this semester's study, I have a new understanding to the software development. When I think that some problems can be solved by programming, it is not only to look at the specific code implementation phase, but need to use a similar to the soft
Excerpt from the original link: YeskyCommon Software ArchitectureL Three-tier architectureIn the design of software architecture, layered structure is the most common and most important structure. The layered structure is generally divided into three layers, from bottom to top: The data access layer, the business logic layer (or become the domain layer), the pres

Therefore, some people often use design pattern) the term refers to the architecture, design, and,ProgramAny type of implementation mode. Others stress that three different layers of patterns should be divided: architectural pattern, design pattern, and idiom ).

Software System deconstruction is a relatively abstract concept. According to my understanding, it can be compared to a bookshelf. The bookshelves are generated as follows: (1) there are not too many books and you can do whatever you want. It is not too messy, difficult to classify and search; (2) more and more books are produced, do you need to consider horizontal or vertical arrangement? It is easy to skip horizontal arrangement, and it is difficult
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
Some time ago after reading the "Internet Age of Software Revolution: SaaS Architecture Design," The book, feeling quite deep. Although many enterprises in 2000 to engage in ASP (Application service Provider, application services provider), but rarely see someone can write a book to share some of the knowledge, this book although write later, but also in the software
Schema definitionThe concept of software architecture is divided into two categories, composed by the software itself as the description object, analysis software composition, decision-making as a description of human decision-making, inductive structure decision-making type.Example of a composition faction definition:
Interfaces are the basic framework elements and important components of high reusability software architecture. It seems that the importance of interfaces is exaggerated, but this is not the case.The C ++ framework that was first favored by most programmers in window development was Borland's built-in Owl (Object window Library) in Borland C ++ 1992 in 3.1 ), early C ++ developers should be very familiar wi
During software architecture design, there are three different types of patterns based on different abstract layers: architectural pattern and design pattern) and code pattern ). The architecture model is a high-level system strategy involving large-scale components, as well as the overall nature and mechanics. The quality of the
Red Hat embraces 64-bit ARM architecture and encourages Linux software development AMD Opteron A1100 Series developer kit with 64-bit ARM processors and Red Hat Linux environments released in July 30, Red Hat) on the same day, the "ARM Partner Early Access Program" was announced to assist the industry in designing a 64-bit ARM architecture including the Red Hat

As pictured above 1.J2EE is divided into 3 layers:Server-side business logic (with business logic tier and persistent data tier, businness Tier and EIS Tier), server-side presentation layer (Web Tier) and client presentation layer (clients Tier) The Java EE design pattern can be summed up to 6 categories(1) Presentation layer architecture pattern (server-side presentation layer)A. Front-end Controller modeB.MVC modeC. Adorner mode(2) Presentation Lay
application services and database services), most of the C/s structure. Application Server mode is the same, browser layer, Application server layer, the database server layer, so Yue three layer (the client/server mode of the server split into two servers to use.) ), most of which is B/s structure There is also a situation of the three layer, is the software architecture of the three layer: user interfac
functions like modifying pencil words, and quickly adapt to new requirements of the system like variables, this system is a very adaptive system for changes. What are the benefits of a system that is highly adaptable to changes? Let's take an example. When I was writing with a pen, the teacher always asked me to write it in a square lattice. There was no typo, no mistake, or a mistake. If it was wrong, I had to rewrite the whole page. If the wrong word is written in the first line, the rewritin
