| Because of the increasingly acute competition of high-tech,These days the policy decision made by applying the systematic quantitative and qualitative analysis based on the scientific methods will take the place of the traditional managing skills rooted in creative abilityjudgement,intuition and experiences unddvoidably.On the background of Dalian Maritame University science and technology information decision support system construction faced with the deficience of data independence and duplication in its many-year used files processing system and the late demands of the new environments against the science and technology managements;This paper analysis detailedly the business activities and function needs of the system and defines that the intelligence and ability dcision system with multi-model peocessing constructive is the optimum solution scheme to realize the system destinations.In the paper,the relative concepts such as association rule and principles are analysed and elaborated systematically,systemanalysis and design is achieved by using well-defined and great function uml and datamanaging of sytem is realized through VB6.0 to put the emplying knowledge out of the quantum datas,the paper also performs multidimension databases data forms on the support dicision layer. Confronted with the massivedatas in the multidimensional database,regressing analysis model is applied to forcast and to help decisions .As far as knowledge discovery is concerned,the association rulesmethods are choosed to complete the data mining .the useful knowledge is drawn out of the database to realize the decision support .the realization of dalian maritame university information decision support system will improve the decision quality effectively .direct and hamonize the development of science and research,accelerate science and technology boom,and make Dalian Maritame University to hold her advantage in science and technology competition inthe new surroundings and forms.
