[Collection] e-commerce platform construction

I was asked about the e-commerce process during the last grand interview. Finally, I sorted it out. For future use.

1 Overview (concept/role)
E-commerce refers to the use of modern computers, network communications and other technologies to achieve information, digitization, paperless and internationalized business activities. In a narrow sense, e-commerce is electronic trade. It mainly refers to the use of web-provided means to conduct electronic transactions, buy and sell products, and provide services. In a broad sense, e-commerce also includes internal business activities, such as production, management, finance, and inter-enterprise business activities. Through e-commerce, the following goals can be achieved:
· Enable sellers to "sell" to the whole world through online sales, so that consumers can "buy" all over the world without leaving home.
· Online sales, online shopping, and online payment can be achieved, so that sellers and enterprises can track customer shopping trends in a timely manner.
· Merchants and enterprises can use e-commerce to widely spread their unique images on the Internet.
· Merchants and enterprises can use e-commerce to maintain close contact with partners and improve cooperation relationships.
· It can provide customers with timely technical support and technical services to reduce service costs.
· It can facilitate information exchange between merchants and enterprises, obtain various information in a timely manner, and ensure scientific and timely decision-making.

2. E-Commerce classification
· Enterprise-to-individual e-commerce (B2C ):
In recent years, a large number of online stores have emerged. Because the Internet provides two-way interactive communication, online shopping has become a hot topic. This mode saves the time and space for both the customer and the enterprise, greatly improves the transaction efficiency, saves all kinds of unnecessary expenses, and achieves rapid development.
· Enterprise-to-enterprise e-commerce (B2B ):
Companies can connect key business processes in electronic form to form virtual enterprises. Despite the strong momentum of online companies' direct sales to customers (B2C), many analysts believe that business activities among enterprises are more promising.
· Individual-to-individual e-commerce (C2C ):
Individual-to-individual e-commerce is a special e-commerce. It refers to the business process of different individuals through the Internet. The most typical business activities include online auction.
· Internal e-commerce:
The Enterprise Intranet can be used to automatically process business operations and workflows, increase access to important systems and key data, jointly solve customer problems, and maintain inter-organizational relationships.

3 Problems to be Solved
E-commerceThe following problems must be solved:: Information flow, capital flow, logistics and security issues. Solving these problems will be the key to the success of e-commerce.
· Information Flow:
Information Communication in traditional commerce will spend a lot of time and energy, and the transaction cost is very high. The use of electronic information exchange in e-commerce will make the business process fast, open, low-cost, accurate, break the region restrictions. Solving the problem of information flow is the key to the success of e-commerce.
· Capital flow:
The information flow only solves the information exchange between all parties involved in the business. To complete the entire business process, the transfer of funds is required. Therefore, e-commerce cannot be implemented if the capital flow problem is not solved. Capital flows must be handled by e-currency and online banking.
· Logistics:
E-commerce accelerates the business process and reduces intermediate links, but the logistics process is irreplaceable, and even increases the traffic and difficulty of logistics. However, the huge benefits of e-commerce will not be hindered by this problem. The key lies in how to solve it.
· Security:
Security is a necessary condition for ensuring the smooth completion of the e-commerce process. As the transaction sides do not meet each other in e-commerce, there will be many problems that will not occur in traditional business models, essentially the security of transactions. Therefore, security issues in e-commerce must be solved by technical and credit means.

4. E-Commerce Development Process
In the process of e-commerce development, it goes through the initial stage, functional stage and integration stage.
· Initial stage:
In the initial stage, enterprises only publish product information through simple websites. Other elements of e-commerce are imperfect. Therefore, a large amount of money, manpower, and material resources are required to achieve the entire process of e-commerce.
· Function stage:
In the function phase, enterprises have established relatively well-developed online transaction systems and logistics systems to complete basic e-commerce functions, therefore, it is not a perfect e-commerce.
· Integration stage:
In the integration phase, various factors of e-commerce, such as ERP, CRM, SCM, OA, online portal, and e-payment systems, are well integrated, the efficiency of e-commerce is greatly improved.
