Many beginners are not very clear about what are the characteristics of the cUnix s test and the bamp s test. in order to help you solve this problem, the following editor will explain it in detail for you. People with this need can come and learn. I hope you can get something.

The two modes are often used by us, the server is responsible for the data management, and the client is responsible for the interaction with the user; the bAccord s mode is a network structure mode after the rise of WEB, and the WEB browser is the most important application software on the client side. Next, let's take a look at the relevant contents of the cswab s test and the bamp s test.

1. From a testing point of view, cs can be divided into three parts, as follows:

A, a separate client

Integrated testing of b, client and server

Integrated testing of C, client, network and server

2. Comparison of structural characteristics between cs and bs.

A, most of the pressure of bs is on the server side; in the case of cs, the client side can share the write pressure

B, cs programs need to consider different versions of os

C. The cost of maintenance and upgrade of cs is high.

3. Advantages and disadvantages of cs:

The advantages of Cpact S model

Because the client is directly connected to the server, there is no intermediate link, so the response speed is fast.

The operation interface is beautiful and various, which can fully meet the personalized requirements of customers.

The management information system based on Cpact S structure has strong transaction processing ability and can realize complex business processes.

The shortcomings of the Cpact S model

Need special client installation program, distribution function is weak, for a wide range of points and do not have the network conditions of the user group, can not achieve rapid deployment, installation and configuration.

Poor compatibility, for different development tools, has great limitations. If you use different tools, you need to rewrite the program.

The development cost is high, and it can only be completed by technicians with a certain professional level.

4. The advantages and disadvantages of BBGUA S mode.

The advantages of BDUBUBER S mode

It has the characteristics of distribution, and can query, browse and other business processing anytime and anywhere.

The business expansion is simple and convenient, and the server function can be increased by adding web pages.

Maintenance is simple and convenient, only need to change the web page, you can achieve synchronous updates for all users.

The development is simple and the sharing is strong.

The shortcomings of the BBUBERS model

The characteristics of personalization are obviously reduced, and it is impossible to achieve the functional requirements of personalization.

The operation takes the mouse as the most basic mode of operation, which can not meet the requirements of fast operation.

When the page is dynamically refreshed, the response speed is obviously reduced.

The paging display can not be realized, which causes great pressure on database access.

The function is weakened, so it is difficult to realize the special functional requirements under the traditional mode.

5. Factors affecting the performance of CS/CSS system architecture.

It is very difficult for test engineers to test the performance of a CS/CSS system because of the following characteristics:

Various parts of the system use a variety of operating systems, and there are differences in performance.

Multiple databases are used in all aspects of the whole system architecture, and there are also differences in performance.

Applications are multiple, belong to multiple categories, and are distributed on different devices, including self-developed applications and third-party applications

The devices and components in the system connect and communicate through different protocols.

The system has many internal interfaces and performance bottlenecks, while the overall performance of the system often depends on the worst part; it needs to be tested separately and jointly.

The performance index of the system is related not only to the application system architecture, but also to the business model of industry-specific applications.

The industry application using this architecture is often a 7 × 24-hour system.

Industry applications that adopt this architecture may have more high-end business, which will affect the selection and conversion of performance metrics.

Each link basically communicates in the way of exchanging data messages, and its format is often complicated.
