Read/write Architecture This example illustrates how to read the XML Schema Definition Language (XSD) file to the schema object model (SOM. This example then writes the XSD Schema that has been loaded into the memory to stringwriter to display it on the screen. You can also use xmlwriter to write the schema to a file. The SOM provides a set of classes that directly reflect the W3C XSD specifications. The classes, methods, and attributes of XMLSCHEMA c

Summary of Oracle database architecture, oracle Architecture Oracle DB Architecture An Oracle DB server consists of one Oracle DB and one or more database instances. An instance consists of a memory structure and background processes. Whenever an instance is started, a shared memory zone called the system global zone (SGA) is allocated and background processes

The transformation of Google architecture from failover system to multi-homed architectureRunning a single data center is difficult, so switch to a dual datacenter if you need to support multiple data centers in different geographies. Google has a thoughtful, thought-provoking paper that describes the process-"large-scale high availability: Building Google's advertising data infrastructure."The main idea is that a typical failover

Like you just started building a house because of the low-level popularity of the roof bungalows This is a kind of architecture (v5t) and then this cottage structure you can design a separate bathroom style this is called the ARM7 kernel and then others (Chip design company) want to build the house to buy you this drawing to cover and then after a period of time Some people think that the light independent bathroom is not enough ah, I also want to hav

Today, my colleague asked me what is the use of web service in the system? What is the difference between it and the general direct writing on the client? What are the advantages? It is really interesting to answer this question. Since I have asked this question, it means that there are some preconditions for not reaching an agreement. It is easy to explain the technology itself. Therefore, we should first clarify the background of recommending the use of the SOA

High concurrency Server Architecture Evolution of large website architecture Three server requirements: High Performance: rapid response to a large number of requests High Availability: uninterrupted, automatic failover occurs, which is called fail over (Failover) Scalability: Cross-machine communication (TCP) In addition, any network system structure can be abstracted into a C/S

Recently, the company requested that the architecture of a product be changed from two layers to three layers (the reason is: For security review, a three-layer architecture is required because the database port is only open to the server ), when I heard it, I fainted. The initial architecture of the product was three layers. Later, due to various requirements du

In the technical documentation, we often find that topology, architecture, and struct are not strictly differentiated. Sometimes we can see that a topology becomes a pure echure, and sometimes a struct becomes a pure echure.From a rigorous point of view, how should we define and distinguish them for correct use? My personal understanding is as follows: 1. the focus of topology is network deployment, such as the distribution of data centers. architechu

Advantages and disadvantages of C/s architecture:Advantages1. Because the client is designed independently, it can realize the personalization2. Because the client needs to be installed, it can not need to be installed and loaded repeatedly3. Because the client is independently developed, it has the ability to design the client securely4. If you encounter different operating systems, you need to develop a set of clients for different operating systemsDisadvantages1. Because the client is not req

The last section of the "large-scale Web site Architecture Evolution", today to talk about the structure of the model, what is the model? Each pattern describes the core of a problem and problem solution that repeats itself around us, so that you can reuse the program over and over again without having to do repetitive work, and the key to visible mode is repeatability.The goal of the Web site architecture
