The Rearch And Implementation Of Information Publishing System Based On 3-tier C/S Architecture

To realize the collection, review, publishing and search of dynamic information, system for information publishing and information maintenance based on database is needed to establish, so as to automate the information publishing and information maintenance for web site.Under the research and analysis the character and technology of the typical information publishing system, this paper puts forward the solution based on 3-tier C/S architecture aiming at the deficiency of traditional information publishing system based on 2-tier C/S architecture and carries out the framework of system, including the general design and module design. At the same time, this paper puts forward the difficulties of technology and the solutions for system security.3-tier C/S architecture will be the progress direction of information publishing system, because it is reliable, retractile and easily maintained. This paper lucubrate 3-tier C/S architecture and COM component technology, it presents the Client/Server model and the development flow of COM particularly. Finally the development details of establishing this system based on 3-tier C/S architecture is given out.This system has been practically applied on Jiangjin governmental public information web site, it not only has the character of easily maintained, prompt search, easily managed as the traditional information publishing system based on 2-tier structure, but also has the advantage of the system based on 3-tier architecture, the performance guideline of this system reaches high standard. On account of realizing by using COM component, this system has strong expansibility, the user can develop and expand the function based on this system to adapt his own web site, this system has superior performance and strong function, it ensures timely information updating for web site, In conclusion, it has high actual utility.
