What is an e-commerce architect?

What is an e-commerce architect? E-commerce architects play an important role in the whole process of e-commerce development, and their responsibilities or concerns are constantly changing with the development process. In the requirements phase, the architect is mainly responsible for understanding and managing the non-functional system requirements, such as software maintainability, efficiency, reusability, reliability, effectiveness and testability. In addition, architects should constantly review the requirements put forward by customers and marketers and confirm the designs put forward by the development team. After the requirements became more and more clear, the focus of architects began to shift to organizing the development team members and defining the development process. In the software design stage, the architect is responsible for the design of the whole software architecture, key components, interfaces and development strategies; In the coding stage, architects become consultants to detailed designers and coders, and often hold some technical seminars and training courses. With the development of software testing, integration and delivery, integration and test support will become the focus of software architects. At the beginning of software maintenance, software architects begin to decide whether new functional modules should be added to the next version of the product.

prerequisite

The formation of architects is exercised in practice, which requires considerable technical level and years of practical experience, rather than taking a few training courses and reading a few books. Obviously, in the process of software development, the importance of an excellent software architect cannot be underestimated. So how to become an excellent software architect?

Leadership and teamwork skills, software architects must be recognized as technical leaders and be able to make timely and effective technology selection decisions at critical moments.

-Strong communication skills, which seems to be the best of all roles at that time. Software architects need to deal with people from all walks of life, such as customers, marketers, developers, testers, project managers, network administrators, database engineers and so on. , and also plays the role of disseminator in many roles. In terms of technical ability, the most important knowledge that software architects need to master is the knowledge of component communication mechanism, such as remote procedure call, JAVARMI, CORBA, COM/DCOM, various standard communication protocols, network services, object-oriented databases, relational databases, etc. In addition, architects should always pay attention to the development of new software design and development, and constantly explore more effective new methods. Development languages, design patterns and development platforms are constantly upgrading rapidly. Software architects need to absorb these new technologies and knowledge and apply them to software system development. Of course, the business knowledge of the industry is also very important for software architects, which is helpful for design.

To develop an architecture that meets the needs of customers, excellent software architects often need to learn quickly and observe keenly in order to get an understanding of the industry business as soon as possible.

The above description is boring, but as an architect, it is fun in the whole software system development process, because this role is very challenging, sometimes it needs to be balanced and delicate, and sometimes it needs to be decisive and firm. In China, few software companies have independent architects. Usually, a software expert is a project manager, a software architect and a software developer, and sometimes a guest tester, which is unfavorable to the software development cycle and product quality. Sometimes, a person's views and positions are very one-sided. Heavy work and pressure will affect a person's mood, which will affect the decision, and the decision will affect the result, so it is worth our second thought.

Architects can't get it through theoretical study, but they can't do it without learning relevant knowledge. Summarize the self-cultivation process of architects as follows.

1, architect embryo (programmer)

Learning knowledge is the foundation of language, design and communication. These should be completed in universities, including java, C, C, uml, RUP, XML, socket communication (communication protocol)-essential raw materials for learning to build application systems.

2. Up-and-coming architects (senior programmers)

Learn about distributed systems, construction, etc. You can get in touch with them in university or during the first year of work, including distributed system principles, ejb, corba,/,webservice (graduate students can learn network computers, efficient concurrent processing, etc. )

3, architect Miao Zi (designer)

On the above basis, combined with the actual project experience, deeply understand the application design patterns, including design patterns (C version, java version), ejb design patterns, J2EE architecture, UDDI, software design patterns and so on. In the meantime, it is best to understand the application of software engineering in actual projects, team development and team management.

4. The formation of software architects lies in opportunities, personal efforts and talents. Software architect is actually a position, but how can programmers get such an opportunity, how to make a reasonable framework for applications by using their own skills, how to constantly abstract and summarize their own framework patterns, and how to go deep into the industry to become an elite who can analyze and frame? ...

Basic authentication

As we all know, Java is the most popular software development language at present, which has the characteristics of cross-platform, object-oriented and powerful network functions. You can use Java programs not only on your computer, but also on your mobile phone, PDA and household appliances. Even the world-famous rovers all adopt Java technology. Java has become the most popular software development platform in less than 10 years, and the latest enterprise Java version 2.0 (J2EE for short) has also become the most popular development standard in enterprise application systems.

In fact, the supply of J2EE architects all over the world is in short supply, but this is more obvious in China. In Britain, the average annual salary of experienced J2EE architects has soared to 70,000 to100,000. Mark Ashton, technical service director of SilverStream Software Company, a world-renowned e-commerce platform provider, deeply felt the shortage of J2EE talents. He said that many job seekers listed J2EE in their resumes, but after careful examination or interview, most people only heard of J2EE and never really used these technologies. Ding, deputy director of the Department of Electronic Information Products Management of the Ministry of Information Industry, recently said that there are far from enough Java talents in China, at least 200,000. Especially with a large number of software outsourcing businesses entering China, many foreign-funded or Chinese-funded software enterprises are facing the shortage of high-level Java talents, especially those who are familiar with J2EE and can master a corresponding foreign language.

As the inventor of Java and the main maker of Java development standards, Sun Company of the United States provides three-level certification system for technicians engaged in Java development, namely junior programmer certification (SCJP), intermediate developer certification (SCJD and SCWD) and senior architect certification (SCEA). This is also one of the most authoritative international certifications in the software industry. At present, there have been trainings aimed at the certification system of Sun Company in the United States in China, but most of them are based on the certification of junior programmers, and only a few professional training institutions can provide three-tier complete training.

5. If you are selling products, the warehouse staff must be indispensable.

Used for packaging and delivery. Organize warehouse resources.

Generally speaking, an e-commerce company needs: operation, art design, promotion, customer service and warehouse personnel.

Briefly describe the service architecture of e-commerce. E-commerce is a business activity centered on commodity exchange with the help of information network technology. It can also be understood that trading activities and related services are conducted in the form of electronic transactions on the Internet, intranet and value-added network, which is the electronization, networking and informatization of all links of traditional commercial activities.

E-commerce usually refers to a new business operation mode in which buyers and sellers conduct various business activities without meeting each other in a wide range of business and trade activities around the world under the open network environment of the Internet, and realize online shopping for consumers, online trading for merchants and online electronic payment, as well as various business activities, trading activities, financial activities and related comprehensive service activities. Countries, scholars and business people have given many different definitions according to their respective positions in e-commerce and different angles and degrees of participation in e-commerce. E-commerce is divided into ABC, B2B, B2C, C2C, B2M, M2C, B2A (namely B2G), C2A (namely C2G), O2O, etc.

Let's start with the home page architecture of several major types of e-commerce networks. It is convenient for SEO to optimize search engines.

What is the vertical architecture of e-commerce system? I study e-commerce. Tell me about some professional courses I have taken in recent years. Let alone other ideological classes and English mathematics. Three years, even junior year. There is still one semester, and the course is still unknown. I guess it's almost over.

Introduction of seven-layer architecture and OSI seven-layer model of e-commerce security

OSI is an open access system interconnection reference model, and it is a well-defined protocol specification. The OSI model has seven layers, and each layer can have several sublayers. Let me briefly introduce these seven layers and their functions.

The seven layers of OSI are from top to bottom.

7 application layer

6 presentation layer

5 session layer

4 transport layer

3 Network layer

2 data link layer

1 physical layer

Among them, the top layer (7, 6, 5 and 4) defines the functions of the application, and the bottom layer (3, 2 and 1) mainly faces the end-to-end data flow through the network. Let me introduce the functions of these seven layers to you:

(1) Application layer: an application program that communicates with other computers, corresponding to the communication service of the application program. For example, a word processor without communication function cannot execute communication codes, and programmers engaged in word processing will not care about the seventh layer of OSI. However, if the option of transferring files is added, then the programmer of the word processor needs to implement Layer 7 of OSI. For example: telephone, http, FTP, NFS, SMTP, etc.

(2) Presentation layer: The main function of this layer is to define data format and encryption. For example, FTP allows you to choose to transfer in binary or ASII format. If binary is selected, the sender and receiver will not change the contents of the file. If ASII format is selected, the sender will convert the text from the sender's character set to standard ASII, and then transmit the data. Convert the standard ASII into the character set of the receiving computer at the receiving end. For example: encryption, ASII, etc.

(3) Session layer: it defines how to start, control and end a session, including the control and management of multiple two-way hours, so that the application can be notified when only part of the continuous message is completed, and the data seen by the presentation layer is continuous. In some cases, if the presentation layer receives all the data, these data will be used to represent the presentation layer. For example: RPC, SQL, etc.

(4) Transport layer: The functions of this layer include selecting error recovery protocol or error-free recovery protocol, multiplexing the input of data streams of different applications on the same host, and reordering the received data packets out of order. For example: TCP, UDP, SPX.

(5) Network layer: This layer defines the end-to-end packet transmission. It defines the logical address that can identify all nodes, and also defines the way of routing implementation and learning. In order to adapt to the transmission medium with the maximum transmission unit length less than the packet length, the network layer also defines the segmentation method of how to decompose a packet into smaller packets. For example: IP, IPX, etc.

(6) Data link layer: It defines how to transmit data on a single link. These protocols are related to the song media in question. For example: ATM, FDDI, etc.

(7) Physical layer: The physical layer specifications of OSI are the characteristic standards of transmission media, and these specifications usually refer to the standards formulated by other organizations. Connectors, pins, pin usage, current, current, coding and optical modulation all belong to various physical layer specifications. The physical layer usually uses multiple specifications to define all the details. For example: Rj45, 802.3, etc.

Advantages of OSI layering:

(1) People can easily discuss and learn the specification details of the protocol.

(2) The standard interface between layers is convenient for engineering modularization.

(3) Establish a better interconnection environment.

(4) Reduce the complexity, make the program easier to modify and product development faster.

(5) Each layer uses the service of the next layer, which makes it easier to remember the function of each layer.

Most computer networks adopt hierarchical structure, that is, a computer network is divided into several levels, and the high-level system only uses the interfaces and functions provided by the low-level system, without knowing the algorithms and protocols used by the low-level system to realize this function; The lower level only uses the independent variables sent by the higher level system, which is the independence between levels. Because of this independence, each module between layers can be replaced by a new module, as long as the new module has the same function and interface as the old module, even if they use different algorithms and protocols.

What is e-commerce? How to do e-commerce well? Is baidu promotion an e-commerce? E-commerce is a business activity using microcomputer technology and network communication technology. Countries, scholars and business people have given many different definitions according to their respective positions in e-commerce and different angles and degrees of participation in e-commerce. However, electronic commerce is not the same as electronic commerce. Commercial and trade activities carried out on a global scale by using electronic tools such as the Internet (these tools include telegraph, telephone, radio, television, fax, computer, computer network, mobile communication, etc. ). It is the sum of all kinds of business activities based on computer network, including the behaviors of providers of goods and services, advertisers, consumers, intermediaries and other interested parties.

First look at the pattern. Before developing e-commerce, the first thing an enterprise should do is to choose a model suitable for its own development. Correct website development and business model can make enterprises avoid detours in network marketing and promotion, save unnecessary expenses to the maximum extent and create maximum profits.

Second, look at technology. The technology here is not only the level of technology itself, but also the service and attitude towards technology. When Jitongbao built a website platform for franchisees, it did not simply consider the function of the platform with its own understanding, but fully combined the franchisees' understanding of traditional industries. After all, franchisees are insiders, and laymen usually get twice the result with half the effort.

Third, look at the price. As the saying goes, "good steel should be used on the blade." Although the legendary e-commerce cost is not high, the cost input is also indispensable. What's more, if you don't understand, even if you invest, you may not get much.

Fourth, look at the service. Users are the key link in the development of website platform. According to the related survey of Jitongbao, 42% people think that the credit, product quality and after-sales service of merchants are the biggest problems in online transactions at present.

Baidu promotion is only a small category in e-commerce.

To do a good job in e-commerce, we must have an orderly thinking and a rich knowledge base.

What is e-commerce and what is e-commerce? 1, the meaning of electronic commerce:

E-commerce refers to commercial activities centered on commodity exchange with the help of information network technology; It can also be understood that trading activities and related services are carried out through electronic transactions on the Internet (Inter), Intranet (Intra) and VAN (value-added Neork), which is the electronization, networking and informatization of all links in traditional business activities.

E-commerce usually refers to a new business operation mode in which buyers and sellers conduct various business activities without meeting each other in a wide range of business and trade activities around the world under the open network environment of the Internet, and realize online shopping for consumers, online trading for merchants and online electronic payment, as well as various business activities, trading activities, financial activities and related comprehensive service activities. Countries, scholars and business people have given many different definitions according to their respective positions in e-commerce and different angles and degrees of participation in e-commerce. E-commerce is divided into ABC, B2B, B2C, C2C, B2M, M2C, B2A (namely B2G), C2A (namely C2G), O2O, etc.

At the same time, network marketing is also the product of e-commerce, and for network marketing, we should make a good network marketing plan before doing it, so as to facilitate the implementation of the plan.

2. Elements:

Four elements: shopping malls, consumers, products and logistics.

1, buying and selling: major online platforms provide consumers with high-quality and cheap goods, attract consumers to buy and promote more businesses to settle in.

2. Cooperation: It is one of the hard conditions for e-commerce operation to establish a cooperative relationship with logistics companies to provide the ultimate guarantee for consumers' purchase behavior.

3. Service: Logistics, one of the three elements of e-commerce, mainly provides consumers with purchasing services, thus realizing another transaction.

3. Associated objects:

The formation and transaction of e-commerce cannot be separated from the following four aspects:

I. Trading platform

The third-party e-commerce platform (hereinafter referred to as the third-party trading platform) refers to the sum of information network systems that provide transaction matching and related services for two or more parties in e-commerce activities;

Second, platform operators.

Operators of third-party trading platforms (hereinafter referred to as platform operators) refer to natural persons, legal persons and other organizations that have registered with the administrative department for industry and commerce and obtained business licenses, engaged in the operation of third-party trading platforms and provided services for both parties to the transaction;

Third, station operators.

In-station operators of third-party trading platforms (hereinafter referred to as in-station operators) refer to natural persons, legal persons and other organizations engaged in trading and related service activities on e-commerce trading platforms.

Fourth, the payment system

Payment system is a kind of financial arrangement, sometimes called clearing system, which is composed of intermediaries and professional technical means that provide payment and clearing services, and realizes payment instruction transmission and fund settlement.

E-commerce, there are portals, relatively perfect information flow, capital flow, logistics and so on.

4. Existence value:

The value of e-commerce lies in allowing consumers to shop and pay online through the Internet, saving time and space for customers and enterprises, greatly improving transaction efficiency and saving a lot of precious time, especially for busy office workers. 2 1 century, consumer information is diversified, and it is possible to stay indoors through online channels.
