Online shopping system

Source: Shangpin China | Type: website encyclopedia | Time: June 27, 2014
Have you ever thought of sitting in front of a computer and clicking to buy something? If you are the boss, have you ever thought about letting people in the supply sector know your company and products as soon as possible through the Internet, releasing products in a timely manner, updating product information in real time, and processing orders quickly to better serve your customers? Electronic commerce can make all this come true. Online shopping system, as an important part of e-commerce, has been gradually popularized in China. Online shopping has the characteristics of low cost, planned inventory, convenient user retrieval, and less restrictions on the city. Although there are still many imperfections, it is gradually accepted by people. After all, this is a trend. There are many e-commerce sites in China, and many portal websites have launched their commercial sites in succession. Figure 6-3 shows the online content sites of Sina. This section will start from the planning of online shopping system. According to the user's online shopping process, it will introduce the construction process of a simple shopping system that is different from ^ A.SP and ^~database step by step, so that readers can have a deeper understanding of the design of shopping website.

1、 Functional analysis

When we plan an online shopping system, we should naturally consider the following questions: 1) Because the items in the online store are constantly changing, such as product name, category, price, etc. But we can't always change the ASP program and web page, so we are asked to come up with a good solution. Don't change the ASP program and web page, Only changing the database file can solve the problem. 2) Since different items may be on different pages, how to know which items are close to users in different pages. That is to say, users can share the same hook. Put the items on all pages in the same box. That is to say, it is necessary to distinguish which segments of customers choose which products.

A canonical Website production The shopping system can be divided into three processes: goods handling process, collection and delivery process and management process. In this section, we only discuss the implementation of the shopping process. Since the collection and delivery process involves online payment, which is beyond the knowledge of ASP, we will not discuss it. The management process only involves general database management and user authentication. After learning the shopping process and other chapters of this book, readers can draw inferences from one instance to realize the functions of the management process.

The shopping process is customer oriented. What we show customers is the elements of a real store. When customers use this shopping system, they should feel that it is similar to the real shopping. All database operations are transparent to users. In a word, we should improve the places that make customers feel inconvenient in real shopping and give full play to the characteristics of the network on the basis of trying to imitate real shopping. This is the core spirit of a network martyrdom system. In the real market, in order to enable customers to find the things they want to buy as soon as possible, they always store the goods in categories. We can easily realize this function in the online shopping system. Because the commodity database is an abstraction of the commodity warehouse in reality, we can define various attributes of commodities in the database, such as category, price, actual inventory, purchase quantity, etc., and then we can display them on the page by category according to these attributes. In contrast, in reality, only one attribute can be classified for storage, and we can select different attributes for classification display by users.

A friend who has been to a large supermarket for shopping must feel that even though the goods have been classified and stored, the place is too large to find things. If only to buy a tube of toothpaste, most people would rather spend more money to solve the problem nearby than go to a large supermarket to buy it. An outstanding advantage of the online shopping system is that it is easy to find. As long as you know one of the keywords of the things you buy, such as a word of a toothpaste brand, you can find it immediately by clicking the mouse.

In order to simplify the program design and leave room for readers to think, we do not intend to implement membership login, but treat all users equally. In addition, in the process of shopping, 'we also introduced the concept of shopping cart. What is a shopping cart? In the real supermarket, you can push the cart, put Zhongyu's goods in the cart, or take out the goods in the cart and travel to the shelf again, and finally push the cart to pay the bill. Then, in the online supermarket, customers should also be able to put their favorite products into the "electronic cart" when browsing the catalog. The electronic cart is the electronic version of the supermarket cart. In online stores, this kind of electronic cart is also called "shopping cart"? From the programmer's point of view, a shopping cart is an object that can maintain the shopper's selection of goods, allow viewing, and allow modification. The shopping cart itself is a very simple program, but developers should consider that it will be connected to the commodity catalog subsystem, order subsystem, customer account subsystem, site management subsystem, etc. to form a fully functional online store.  

2、 Technical scheme analysis

Online shopping system is a typical example of ASP database application. Therefore, the database operation plays an important role in this example. Including: ADODB Corurecti. object and ADODB Create and clear Recordset objects, insert records into the database, update database records, delete database records, and so on. Secondly, because online shopping systems need to determine the identity of users, simple login and authentication technologies are also essential. These technologies have been introduced in the previous section, and will not be discussed in detail here.

In addition, as a practical online shopping system, we need to consider the number of users. We need more advanced hardware and more powerful database system, but this is not enough. Our program also needs some skills to make it work normally under extreme circumstances. Although the skills described below may not be reflected in our programs, after mastering ASP, readers can improve and perfect the sample program according to the following ideas to really build their own site.
