某市政府部门有近30个委、办、局,分别承担着法定的政府职能,这些部门都有信息中心,负责本单位信息系统的建设和信息资源的采集、维护等工作,同时向业务部门提供信息化技术支持。该市的电子政务建设发展很快,统一规划实施了政务内网,实现了各个政府部门百兆以上带宽的互联互通,并在此基础上规划信息资源网。该政务内网的运行维护成本较高,所以在政务内网开通之后,市财政逐渐削减了各个委办局自身信息系统的维护费用,市政府也要求尽快实现信息资源的共享,以发挥电子政务网的效益。 [问题l] 该市决定将各个委办局的信息系统采取物理集中的方式进行统一管理,一些部门对此提出了异议,主要理由是集中管理后,由于管理部门对业务应用不了解,难以保证对本单位业务进行有力支持。 请用300字以内文字,从技术角度论述该市实现信息系统统一管理是否可行。

Thousands of years ago man used handy rocks for his surgical operations. Later he used sharp bone or horn, metal knives and more recently, rubber and plastic. In the 1960s a new tool was developed, one which was, first of all, to be of great practical use to the armed forces and industry, but which was also to revolutionize the art and science of surgery. The tool is the laser and it is being used by more and more surgeons all over the world. As we all know, light is hot, and any source of light will give warmth. But light is usually spread out over a wide area. The light in a laser beam, however, is concentrated. This means that a light with no more power than that produced by an ordinary electric light bulb becomes intensely strong as it is concentrated to a pinpoint-sized beam. Experiments with these pinpoint beams showed researchers that different energy sources produce beams that have a particular effect on certain living cells. It is now possible for eye surgeons to operate on the back of human eye without harming the front of the eye, simply by passing a laser beam right through the eye-ball. Operations which once left patients exhausted and in need of long period of recovery time now leave them feeling relaxed and comfortable. The rapid development of laser techniques in the past ten years has made it clear that the future is likely to be very exciting. Perhaps some cancers will be treated with laser in a way that makes surgery not only safer but also more effective. What do we find after the development of the laser in the 1960s
A. Industrial revolution brought surgery changed greatly.
B. Medical help became available for industrial workers.
C. The study of art went through a complete revolution.
D. Human being’s methods in surgery changed greatly.
入世后的中国证券市场,受经济全球化及金融混业趋势的影响,证券业经过十几年的发展已经成为当今中国计算机应用高度密集的行业之一。高度的信息化使其积累了大量的数据,包括企业内部数据如企业财务状况、产品销售情况等,以及企业的外部数据,如企业产品的市场占有率、客户数量、客户的偏好等等。怎样利用这些数据,深层次地挖掘数据资源并进行分析,使公司的决策者能及时掌握公司的运行情况,并根据这些分析结果制定长远规划,从而提高公司的管理水平和竞争优势,成为证券公司技术部门目前的努力方向。 正是基于以上发生的市场变化,很多知名的证券企业开始谋求通过技术创新来挖掘内部资源,全面提高企业竞争力。某证券作为一家全国性综合类证券公司,是其中最早进行变革的公司之一。该证券成立于1994年,随着该公司业务的不断发展,公司管理层逐步意识,到:要提升经纪业务的核心竞争力,必须改变原有的“以证券交易为中心”的运作模式,引入客户关系管理理念,实施客户关系管理,建立“以客户为中心”的经纪业务运作模式。通过了解客户的行为轮廓、投资需求、投资倾向、风险承受能力,对客户进行有针对性的“一对一”的个性化理财服务,帮助客户实现资产的保值、增值,提高客户服务质量,提高客户的满意度和忠诚度,从而最大化客户对公司的终身价值。该证券期望通过先进的数据仓库技术对经纪业务、客户数据进行强有力的分析,从定量分析的角度认知、了解客户和业务状况,为客户关系管理的成功实施提供理性决策支持。 [问题2] 根据数据仓库的方法学,数据仓库体系架构可以分为五个层次。这五个层次反映了应用运行的基本逻辑结构和过程。每层都具有自己的技术实现方式及相应的评价准则。请用 250字描述这五个应用层次及其功能。
