Design And Implementation Of PDA Application System Of A Company Material Receiving And Dispatching

Most of the current grid company supplies through the project site to complete the receipt and acceptance, but because the scene is usually not the ERP system with real-time log entry receiving the results of the acceptance conditions, and on-site business documents back to a single slow, resulting in system Receipt latency issues; scene receipt and acceptance data depends on the material to manually collate and record data submission timeliness, accuracy, standardization is difficult to guarantee, not a good quality of work and standards to ensure uniformity,3G communication technology in recent years as the representative of the rapid development of mobile Internet, mobile information applications making the industry with the conditions Develop mobile Internet-based materials shipping and receiving software systems, use 3G wireless network power supplies on-site verification, shipping and receiving information, input, etc, can be established in the LAN network enterprise information system for the material expansion and extension, completed in wild, outdoor conditions without LAN shipping and receiving of goods workflow and data entry workThesis using literature research, demand research and analysis, and systems design and implementation methods, according to the theory of software development, information systems development and project management theory theory to analyze the use of sophisticated, suitable system development technology, to meet the electricity companies shipping and receiving supplies mobile application needs Include the following:1. The grid companies shipping and receiving supplies PDA application development based on analysis of the main technology:Combined with the development of domestic and international logistics information, fundamental analysis and research in the following areas of:mobile communication network and information security, database, Android application architecture2 Shipping and receiving supplies PDA application system requirements analysisShipping and receiving supplies PDA applications for the system objectives, functions, data transmission and other aspects of in-depth analysis of the overall design for the next step outline design and provide a reliable basis.3 shipping and receiving supplies PDA applications and detailed design of the overall systemObject-oriented approach in accordance with the system of the network architecture design, system-level design software functions, database design, system data flow design, component design4. System implementation and testingDevelopment of the system implementation, to take the development process to achieve a uniform standard of quality management management, document management, version management, schedule management, and portfolio management unit, the development is completed according to the design requirements to develop detailed test plan for internal testing, including functional testing, fault-tolerant testing, performance testing; improvements in internal testing and end user testing, user testing is complete design and development of on-line operation to achieve the goal...
