what is soa architecture in java

What is software architectureSoftware architecture is divided into logical architecture, physical architecture and system architecture.In general, the system Architect will have a minimum of 3 parts of the document, while the part

Introduced The traditional relational database is suitable for the vertical scaling (scale-up) architecture. In other words, to handle more load, you need to switch to a more powerful computer. A few years ago, this meant that in order to support a horizontal scaling (scale-out) architecture, you had to give up SQL, or use zoning, active-passive replication and

Cisco's NAC Framework is an architecture designed to help multiple hardware and software components work together to protect your network from adverse client attacks. This article mainly introduces the NAC Framework architecture. What is a Cisco NAC Framework component? Cisc

uses some entity objects that specifically encapsulate the data. These objects, collectively referred to as models.Only so MVC has nothing to do with layer three because they use different scopes: three layers can be applied to any language, any technology application, and MVC is just to solve the coupling of the parts of the BS application View layer. They are non-conflicting, can exist at the same time, and can be used depending on the situation.Fo

The CPU architecture is a specification set by the CPU manufacturer for the same series of CPU products. The main purpose is to distinguish different types of CPU. Currently, the CPU on the market is mainly divided into two camps: one is the intel series CPU and the other

What is the difference between XMNXMSXMXXSSFirst of all, Xmn, Xms, XMX, XSS are the JVM's memory configuration parameters, we can modify these parameters according to different needs, in order to achieve the best effect of running the program.Understanding JVM Memory Management Look here: How the JVM manages memoryXms, XMXThe-XMS,-xmx allocation

The Analects of Confucius Zi Lu said: "The name is not regular words, but not words. " Although the term enterprise architecture (EA) originated in the West, its English expression is not so accurate. For example, the "What's XXX" we are used to has two different translation methods. One is "

Many years ago, when I held the ASM/C ++ knife, I thought there was nothing I could not write.ProgramAs long as someone in the world can write it out, I can. But what? Writing out does not mean good maintenance, modification, and reuse. Therefore, we consider object-oriented design patterns and so on. The purpose is to abstract them, abstract complex programming models into simple models that are easy to un

I am going to have an interview today. The interviewer hopes that I will talk more about the architecture design and answer some architecture patterns shared by the tribe on the spot.On the way home, I seriously thought about this question: "What is architecture design ?」

accept MVC and have the ability to cope with the extra work and complexity it brings, MVC will put your software on a new level in terms of robustness, code reuse, and structure. Java Web application development involves several development methods that comply with the MVC design pattern.1: JSP + servlet + JavaBean (EJB) 2: JSP + JavaBean (Controller) + JavaBean (EJB) (model) 3: TDK (turbine, velocity ...) 4: xsp5: JSP + Struts + JavaBean (EJB) Atta

The project structure, the project architecture, the server structure, or the server architecture is a bit dizzy, because the project depends on many other projects, I call him a project structure or a project architecture. I have some knowledge about the project structure because I wrote weekly reports, which

Layer-3 structure explanation The layer-3 architecture adds an intermediate layer between the client and the database, also known as the component layer. Here The three-tier system does not refer to the three-tier physical systems, either simply placing three machines or the three-tier architecture. A B/S application is not only a three-tier

One: DNS introduction: DNS is the abbreviation for the computer domain Name System, domain name, or domain Name service, which consists of a parser and a domain name server. A domain name server is a server that holds the domain name and corresponding IP address of all the hosts in the network and has the ability to convert domain names to IP addresses. Domain name and IP address between the conversion work

, and these objects occupy the memory can not be reused, this time a memory leak occurs.Once this happens in the program, it consumes the system's available memory until the available memory is exhausted. For a computer, a memory leak is very serious and can cause a program that would otherwise run normally to be interrupted directly because of insufficient memory. Exception with

utilization is low. And SMT technology allows a physical core to run two or more threads, can be dynamically switched according to the current situation, if a thread in a standstill state waiting for memory, the other thread's instructions can use the physical core of all the execution unit, so that the physical core to use more fully. For SMT to work, all code and storage portions of the processor need to be replicated or partitioned. For example,

Generally, an Intel-based server is called an IA (intelarchitecture) architecture server, or a CISC (complexinstructionsetcomputer Complex Instruction Set) architecture server, because the server in the IA architecture is a PC-based x86 processor

size of the data area required by the program module in order to allocate its memory when it enters a program module in operation. Like the stacks we know in data structures, stack storage allocations are distributed according to the principles of advanced post-out. Heap-StorageHeap storage allocations are specifically responsible for the memory allocation of data structures that are not determined by the storage requirements at compile time or at runtime.For example, variable-length strings

This is the second article in the series of Web services architecture. Starting from the technical definition of Web services, we will discuss what Web services are. First, the author analyzes in detail the basic role of Web services as software components in the Internet environment from a technical point of view, starting from this basic role, this section desc

servers at the same time As an architecture designer, it is far from enough to understand only programming languages, design patterns, protocols, and various popular and unpopular frameworks. First, he needs to focus on value and how to create value for customers and enterprises. The sensitivity to user interests, market, and business models is extremely importa
