Multi-Business Mall mobile system architecture

The significance of system development
Realizing autonomous pan-in learning mode the mobile learning system based on app has built a mobile classroom environment of anytime, anywhere and on demand, providing learners with open, convenient, personalized learning resources and application platform, realizing the ubiquitous learning way. Mobile learning to become a natural or spontaneous behavior, learners can freely arrange the learning plan according to their own will, active and active to obtain the required knowledge, in a variety of space in a variety of ways to self-study, greatly improving the learner's ability to actively explore the problem, creative problem-solving.

The development of mobile system architecture for multi-business Mall of America: Zhang Li 185-6541.3369 (micro or electric)

System Architecture:

The architecture of the Android system can be divided into four tiers, namely the application layer, the framework layer, the System runtime and the Linux kernel layer. Android, in addition to the mobile phone and other platforms used by the operating system, in the use of many corresponding features of the application, this is called the program layer: such as maps, phone book and browser, etc., the program is generally written in the Java language, can be replaced by other programs, compared to other kinds of operating systems more flexible. So how does the program implement its function? This is going to use the second layer: the frame layer. It is the foundation of Android Development, where developers can personalize their expansion with "inheritance" or use the components they provide to speed up the development of programs, which simplifies component reuse. The third layer: the System Runtime Library, it can be divided into the system library and run time. The system library is an important bridge between the connecting framework layer and the Linux kernel, which is the support of the framework layer, such as surface Manager, media Framework, and web kit, etc., and the program written by Java starts executing when the Android runtime. Finally, the Linux kernel layer, which is based on Android, relies on the Linux kernel for the memory management, process management, and security of its services.
1.3 System Database Design
A database is defined as a specific warehouse in which data is stored and managed according to the structure, kind, attributes, etc. of the data required in the project. In the Smart Mall project, the database function is about: User information, store main information, goods, orders, and order details. Each of the objects involved can be defined as a table in the data, such as table products, table shops, in the table details the type of data, name and other basic properties, so that the system can be run in the successful invocation of information in the database. The SQL statements common to the database are:
Create Database dbname;
create table name; (Creates a new table)
Drop database dbname; (delete)
SELECT * from table where; (selecting specified information from a table according to certain conditions)
Insert into table (FIELD1,FIELD2) value (value1,value2);
Delete from table where; (delete)
The visible database is the important logistics core part of program operation, the integrity of database establishment is directly related to the running result of the whole system program. The basic criteria for establishing a database can be summarized as: 1) naming rationalization, 2) concurrency control, 3) Ensuring data integrity, 4) using view technology, 5) appropriate redundancy.

Analysis on the management mode of American Mission network

1. Pricing strategy

(1) Cost-effective strategy. The selection of the customer-type website is generally characterized by consumers in order to obtain more concessions, so the U.S. network through the reduction of product prices, improve product cost-effective, to attract more consumers. The United States network is the use of its strong bargaining power to obtain a higher cost-effective goods.

(2) Differential pricing strategy. The United States network for the re-purchase of some members of the product will give a certain discount, in order to attract users to buy repeatedly, and through the distribution of red envelopes, to achieve advertising and publicity effect, enhance the stickiness of American group users.

(3) Price stratification strategy. Group buying activities will be based on the number of participants to negotiate with the merchant, the more people participate, the price of goods will be relatively cheaper.

2. Profit mode

The company has a wide range of business and has a wider source of profits. The main revenue source of the corporation can be divided into the following aspects:

(1) As the United States network in the consumer and business between the role of intermediary, it for consumers to find suitable businesses and for businesses to provide a large number of consumer groups. Through the use of advertising and other promotional methods to expand consumer groups, and promote the formation of commodity trading, to earn a middle difference or a portion of the profits of the Business Commission

(2) Customers use the United States to promote the network, the U.S. network to collect the advertising costs.

(3) The U.S. network for businesses to provide activities, exhibition venues, the United States to collect rebates.

In the era of information, it is necessary to promote the product to the road of information, Wisdom Mall is not only the product of the Times, but also the advanced technology crystallization, is the business development of their own products, attracting customers flow of important tools. For the development of the project, the Android platform is a popular mobile device operating platform, mobile phone users on the basis of the use of various applications, not only for such development talent, but also to attract more businesses to start positioning the business opportunities in mobile phone customer flow.
This article mainly explains the application of Android hierarchy, system development, Java language, development platform, database and so on in the development of the whole program.
For the improvement of the system, the system function is further strengthened to ensure the security of data and user's privacy. To improve the lack of the place, so that development can be successful. In the era of being surrounded by information, such online shopping malls as the mobile phone applications will be universal and indispensable, the field of research program development is endless.
