This paper discusses a practical and efficient system by applying mobile software development technologies and ZigBee communication network. To achieve a compact and flexible iOS-based client, this study takes advantage of Model-View-ViewModel pattern as well as Client/Server style. Several encryption technologies such as Message Digest algorithm and Rivest Shamir Adleman algorithm are combined to ensure information security. Compared to the common portable marketing system, the proposed system also provides accurate growth information which is collected by wireless sensor network, and proposes a more flexible design pattern for mobile client hence obtaining a better performance on iOS devices.展开更多

In order to solve this problem, this paper presents a program to achieve viewing the results of examination anytime or anywhere with the help of cell phone applications software. The program proposed to solve the problem that user have to wait for the medical test results for a long time and cause the time waste, compared to the programs which using e-mail, SMS and mailing report card to inform the user the results, this one is to be more efficient, while also better meet user and medical institutions’ requirements. In addition, in order to test the practicality and feasibility of the program, with IOS devices as the material basis, this paper constructs a Web client system, based on the GPRS technology, we can realize the data communications between the Web server and a client which is the workbench IOS devices. Through testing, we can proof this Web client system has certain practical and development value, with the physical examination institutions become popular gradually, I believe that this design ideas of the system will be used extensively in the medical system, and also will bring a person more convenient.展开更多

Then we established a spatial data storage model, which has unified the data standards and achieved the management of spatial data and attribute database. Taking ArcGIS API for iOS as GIS platform, Xcode as the tool, we have realized the functions of data integration, data query, data statistics and fertilization recommendation, and constructed the management and service platform of mobile fertilization expert system.展开更多
