Design And Implementation Of A Mobile Stock Trading System Based On Android

As a combination of wireless transmission and mobile communication network system, the mobile stock trading software has become a comprehensive processing terminal, rather than an ordinary smartphone. The mobile stock trading software has become the most popular stock and trading inquiry tool for the investors, since it breaks through the restrictions of time and space. The Android operating system attracts many attentions from the researchers because of the platform openness, hardware diversity and application richness. However, existing mobile stock trading software based on Android operating system provide users with the simple interfaces and functions, which could not provide the customized services. Thus, it is practically significant to design and implementation Android mobile stock trading software, which could not only meet the user demand in general, but could also provide customized services for varied users with a feature-rich interface and outstanding experience.In the requirement analysis phase of th e system development, this paper analyzes the requirement objectives and tasks of mobile phone stock software system. Furthermore, this paper elaborates the overall demand of both client and broker characteristics. Then, this paper describes the requiremen t of the feature functions. Finally, this paper describes the non-functional requirements of the mobile phone stock software involved in the design process.In the phases of system analysis and design, this paper introduces the design principles of mobile phone stock software and describes the system architecture from three aspects: physical architecture, logical architecture and functional architecture. Then, this paper describes the design details of the basic functions and emphasizes the design features of the system. Finally, this paper describes the design and implementation of mobile phone stock database, including the design basis, the client and server databases.In the phases of system implementation and test, this paper tests the mobile phone stock software. Firstly, this paper introduces the test objectives, steps, the environment and the configuration of system testing. Then, this paper tests the system in detail from both basic functions and features. The test results show that the mobile phone software stocks run efficiently on mobile devices powered by Android system. The system design and development program proves feasible. It hopes that the design, development and implementation of Android phone software stocks could provide a reference for this type of application design and development.
