Since the ancient times,Seal has been affected by the Chinese people,and every celebrity has his own seal. In modern society, not only a person needs a seal, but also each enterprise, company or organization was established with their own seal formation. With the continuous development of enterprise, the complication of company organization, the type and number of enterprises seals are increasing gradually. We all know that even seal is small, it would have legal benefits after marking in some important do-cuments, and also the interests of the involved influence is huge. Moreover,a ranch office around the development is not the same as for a huge corporate organization. Therefore, some of the branch with the traditional common seal, and the rapid development of the branch using the electronic seal.So, it is necessary for enterprise management to keep important seal. For example, the company administration chapter, the financial seal control.The study of this paper is to help companies manage seal. The corporate seal management system which based on workflow is Internet-based management information system, its core is the B/S structure. Using workflow technology to describe the printed apply business processes, at the same time, WWF-based exception handling mechanism has been proposed in the paper and got applied. SMS service as a secondary function of the system increases the practicality of the system.First of all, research corporate seal management system business background and characteristics, on that basis put forward the technical foundation to build the enterprise seal supervision system, including ASP.NET technology, ADO.NET technology, Digital certificate authentication technology, workflow and workflow exception handling techniques and SMS service technology. Workflow technology and workflow exception handling techniques are a key technology in order to adapt to the changing needs of the seal application business. The paper presents to divide module into units, and based on units do exception handling, and use to describe the scope of information anomalies can not predict abnormal, and then to compensate for the exception handling mechanism to meet the exception handling of the seal of the regulatory system needs.Secondly, To explore the technology of system required. On this basis, We conduct research on seal management, identify problems, refine business processes and system functions. On the basis of needs analysis, There are module design, the overall architecture design, system workflow design, workflow exception handling design and SMS design.On this basis, to complete the system database.Finally, through the implementation of the system, corporate seal management system which based on workflow will be able to be used for enterprise applications, and better to manage the enterprise seal business including its involved application. |
