The Design and Development of Fixed Asset Management System based on PDA ABSTRACT
Fixed asset is the important resource to enterprises and organizations. Asset management ensures the rational use of fixed assets. Nowadays, with rapidly expanding business, huge amount of business information, more and more branches, using the traditional fixed asset management mode, such as manual management, reflected in table form, can be quite troublesome, reduce the working efficiency, waste management personnel's energy and time, and increase the cost. The original asset management system developed in PC still requires manual data input. The tracking of asset life cycle is also not perfect. Therefore, an asset management system based on PDA development is very necessary. It can provide a better asset management if used with the original asset management system.
RFID technology can provide users with quick assets data collection, statistics and management. It also can achieve the tracking management for the whole asset life cycle including assert purchasing, inventory, change, retirement and etc. PDA is a personal computer in hand. Its volume is small, and it can be carried to everywhere. This system is designed and developed based on PDA, using RFID to track assets management. It contains three business modules: asset inventory, asset changing and asset retirement. In these three function module, it adopts RFID literacy technology to scan and confirm asset and make labels. By using synchronizing tools, it can download the original asset management data from PC to the PDA, and upload the processed data from PDA to PC. This system can greatly reduce the error, increase the artificial statistical data accuracy, and also greatly improve work efficiency and provide a more scientific method for enterprise to manage assets. 原文请+QQ324,9114辣'文^论.文'网
The system development applies the MVC design pattern, UML (Unified Modeling Language), SQLite database technology, RFID technology, and is developed based on PDA mobile device.
