The Design And Realization Of Guang Zhou Online Bidding Procurement System

Online government procurement is the whole process of government procurement, which is based on the internet platform for online government procurement activities, with the use of the online computer networks and communication technology. It is an important component of the construction of the government procurement information, and is also the combination of government procurement management and online business. Online bidding procurement is a model of government procurement. It refers to Internet-based platform for online government procurement auction conducted by the procurement system. It is the whole process of government procurement, which identifies suppliers by the lowest price. The online bidding procurement system of this paper is a subsystem of government procurement platform which is designed and realized basing on the old system. It makes the procurement management become more scientific, standardized, as well as rationalized, and the order of government procurement become further regulate by realizing the business process of the online bidding procurement which is based on the principle of low-cost transaction.

On this basis, it proposes internet-based online bidding procurement system concepts and models, as well as discusses the purpose and principles of its design. At the same time, by fully comparing the service platform architecture before and analyzing the current business needs, it conducts a needs analysis and the overall design on the system. With the practical application of the . Net platform tools and the B/S architecture technology, it gives the specific design and implementation process of the auditing project and announcement management module. In addition, in order to ensure the safety of system operation, the system will dock with the CA server through the design of the interface.

The system is fully functional, and of good stability, openness, flexibility, security. Government procurement business processes with computer-aided, solves the low efficiency and other issues caused by procurement of large and involves. And with the use of mature B/S architecture, as well as the development of three-tier architecture based entirely on the Web, it is easy to upgrade, maintain, apply and promote later, which fully reflects the thought of the government procurement open, fair and just.
