One is for innovation of this text : first , combine the instance , explain that concentrates resources , it is ways of medium and small - scale oil enterprise ' s development to take the . specialization of the products , subdivide the market in some , can contend with the well - known brand ; second , divide rapeseed oil into four inferior markets further on the basis of market survey , expanding the products for enterprises , enrich the variety , the person who meets different demands has offered the theoretical foundation ; third , the setting - up of the marketing channel of market of meagre profit products , such as more systematic exposition grain and oil food , etc . , change distributor system in the past , marketing channel should from pyramid to do away with a hierarchical system short channel was changed , turn into a terminal market building for the centre for the centre by the exclusive distribution goods 本文的创新之处是:一、结合实例,阐述了集中资源,走产品专业化是中小型油脂企业发展的路子,在某些细分市场,是可以和知名品牌抗衡;二、在市场调研的基础上,进一步把菜籽油分为四个亚市场,为企业扩展产品,丰富品种,满足不同的需求者提供了理论依据;三是较系统的阐述了粮油食品等微利产品的市场销售渠道的建立,改变过去的经销商制度,销售渠道应由金字塔向扁平化短渠道转变,由总经销货为中心变为终端市场建设为中心。
In the paper , the hierarchical system architecture of the information management system is introduced , the essential database tables needed for the information system to work is analyzed , the application of tree component in the system and the methods to deal with related events are concerned , finally , the data input and output of mining plan are discussed 提出了该信息系统的多层体系结构,分析了系统运行所需要的基础数据表,及树型组件在此信息系统上的应用和相应事件处理方法,最后对采掘计划数据的导入和导出做了论述。
Based on the realization and study of pkt / pmi theory , this paper introduces the security strategy and technology grounded on the pki to the e - govcrnment applications . it satisfies the information security requirements of confidentiality , integrality and ineontestability of the e - government development . from the point of view , of adapting the applications , this paper proposes the hierarchical system of setting up the secure e - government 本文在对公钥基础设施pki pmi的理论、实现和应用研究的基础上,将基于公钥基础设施的安全策略和技术引入到电子政务的应用中,通过pki pmi的信任和授权服务技术来解决电子政务发展对信息安全的机密性、完整性以及不可否认性的要求。
