S Power Company’s Shipping And Receiving Supplies PDA Application System Design And Implementation

Most of the current grid company supplies through the project site to complete thereceipt and acceptance， but because the scene is usually not the ERP system withreal-time log entry receiving the results of the acceptance conditions， and on-sitebusiness documents back to a single slow， resulting in system Receipt latency issues;scene receipt and acceptance data depends on the material to manually collate andrecord 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 rapiddevelopment of mobile Internet， mobile information applications making the industrywith the conditions. Develop mobile Internet-based materials shipping and receivingsoftware systems， use3G wireless network power supplies on-site verification，shipping and receiving information， input， etc.， can be established in the LANnetwork enterprise information system for the material expansion and extension，completed in wild， outdoor conditions without LAN shipping and receiving of goodsworkflow and data entry work.Thesis using literature research， demand research and analysis， and systemsdesign and implementation methods，according to the theory of software development，information systems development and project management theory theory to analyze theuse of sophisticated， suitable system development technology， to meet the electricitycompanies shipping and receiving supplies mobile application needs. Include thefollowing:Combined with the development of domestic and international logisticsinformation， fundamental analysis and research in the following areas of: mobilecommunication network and information security， database， Android applicationarchitecture.Shipping and receiving supplies PDA applications for the system objectives，functions，data transmission and other aspects of in-depth analysis of the overall designfor the next step outline design and provide a reliable basis.Structured analysis approach in accordance with the system of the networkarchitecture design，system-level design software functions，database design，system data flow design，component design.Development of the system implementation，to take the development process toachieve a uniform standard of quality management management， documentmanagement，version management， schedule management，and portfolio managementunit， the development is completed according to the design requirements to developdetailed test plan for internal testing，including functional testing，fault-tolerant testing，performance testing; improvements in internal testing and end user testing， user testingis complete design and development of on-line operation to achieve the goal.
