Based On The .Net Framework 4.0 Electronic Money To Canvas For System Design And Implementation

With the rapid development of society, the traffic congestion has become urgent to solve the problem of city inside, the emergence of the subway to alleviate this problem, not only to the city brought great social benefits, also brought a lot of benefits. Electronic money subway card can not only replace the ordinary paper tickets as the subway vouchers, but also can be used as electronic money, in the subway station and the surrounding area to join the shopping malls, supermarkets, restaurants, entertainment places instead of cash. Based on the requirement of electronic money, a metro card is inevitable, the design of electronic money subway card system is in urgent need of.The system from Japan X company online system, the company from 2005 to 2014 using the original system, but a lot of changes along the subway station and the surrounding facilities, a significant increase in traffic subway stations, shops, stores, making the original system can not meet the actual needs of economic development in many ways, the work of upgrading the system is imperative. System needs analysis is in the actual operation of passenger and consumption, and the Metro system, made field trips, after a clear need to further outline design the system through explicit, detailed design of the system embodied by the programmer according to the detailed design model code book, and finally by testers for system inspection in accordance with the test stylebook.Innovative design of the system on the relationships between entities, each entity has its unique functions and have the interests of the relationship between each level, under the same companies, terminals use the system without additional consumption points, different companies use the system has additional consumption points, different companies, different stores at the terminal using the system, there are two additional points disappear, interest entities is complex, but also to reflect the addition of new systems such as the franchise group made business expansion.The system in the frame from.Net Framework 2 upgrade to.Net Framework 4, C#4.0 as the development language, considered by the distributed processing requirements and the efficiency of the system, the operating environment for the WAN Visual Studio 2010 and SQL Server 2008 database development under the B/S framework. The browser is responsible for the input, output and management of data, the server is responsible for data storage and access etc. The final realization of the design and implementation of electronic money subway card system.Design of electronic currency subway card system makes the subway card and electronic money card combination, advocating a multi-purpose card concept, with the level of information processing speed, greatly facilitate people’s travel and shopping. After debugging, the system has been officially put into use, the system interface is simple and beautiful, perfect functions, basically meet the needs of customers, to achieve the desired effect.
