城市公共基础数据库建设参考方案

城市公共基础数据库建设参考方案

城市基础数据库系统建设方案

1.系统概述 长期以来,政府各部门内部拥有着大量城市基础数据资源,但由于管理分散,制度规范不健全,造成重复采集、口径多乱、数出多门;各部门的指标数据自成体系,标准不一,共享程度较差。随着政府向“经济调节、市场监管、社会管理和公共服务”管理职能的转变,就要求必须能够全面、准确掌握全地区经济社会发展态势,强化政府部门掌控决策信息资源的能力,政府部门间信息资源整合与共享需求越来越紧密,但当前部门间信息共享多是点对点方式,

没有统一的数据交换管理平台。因此各部门对加快解决数据资源分散管理、数据共享不足的问题需求十分迫切,需要建立城市基础数据库(以下简称智慧城市公共基础数据库)系统以解决以上问题。 依托智慧城市公共基础数据库系统的建设,可以实现各委办局、各所辖地区的经济社会综合数据采集交换,为各部门提供更广泛的信息共享支持,一方面数据信息从各委办局、各所辖地区整合接入,另一方面也为政府和这些接入部门提供全面的共享服务。同时,以智慧城市公共基础数据库指标体系建立为基础,整合来自各委办局和各所辖地区的、经过审核转换处理的数据资源,可实现对经济社会信息的统一和集中存储,确保数据的唯一性和准确性,为今后政府工作提供一致的基础数据支持。 数据整合共享只是手段,数据分析服务才是目的。依托智慧城市公共基础数据库系统建设,可有效整合各政府部门所掌握的全市经济社会信息资源,满足政府业务对统一数据资源共享需要,进而提升形势分析预测水平,对政府在发展规划、投资布局、资源环境、管理创新、科学决策等业务提供强有力支持,提高了政府部门掌控全市经济社会发展态势能力。 2.建设目标 1)建立科学合理的智慧城市公共基础数据库指标体系,力求全面反映地区经济和社会发展的总体情况: 2)有组织、有计划、持续地对政府统计部门、政府各部门以及国民经济行业管理部门负责统计的关系到地区经济与社会发展的信息资源进行收集、整合,建立全地区城市信息资源共建、共享的统一管理机制; 3)依托地区电子政务基础设施,充分利用现代信息技术,以科学的地区宏观经济和社会发展指标体系为基础,建设支持政府宏观经济管理和社会和谐发展的基础数据库系统,提高信息资源的建设、管理和共建共享能力; 4)为地区经济建设和社会和谐发展提供一致的城市基础数据,为各类应用系统建设提供基础数据支持,满足政府管理决策、部门信息共享和社会公共服务“三个层次”的需求。

数据库基础教程课后习题答案顾韵华

习题1 1、简述数据库系统的特点。 答:数据库系统的特点有: 1)数据结构化 在数据库系统中,采用统一的数据模型,将整个组织的数据组织为一个整体;数据不再仅面向特定应用,而是面向全组织的;不仅数据内部是结构化的,而且整体是结构化的,能较好地反映现实世界中各实体间的联系。这种整体结构化有利于实现数据共享,保证数据和应用程序之间的独立性。 2)数据共享性高、冗余度低、易于扩充 数据库中的数据能够被多个用户、多个应用程序共享。数据库中相同的数据不会多次重复出现,数据冗余度降低,并可避免由于数据冗余度大而带来的数据冲突问题。同时,当应用需求发生改变或增加时,只需重新选择不同的子集,或增加数据即可满足。 3)数据独立性高 数据独立性是由DBMS 的二级映像功能来保证的。数据独立于应用程序,降低了应用程序的维护成本。 4)数据统一管理与控制 数据库中的数据由数据库管理系统(DBMS )统一管理与控制,应用程序对数据的访问均经由DBMS 。DBMS 提供四个方面的数据控制功能:并发访问控制、数据完整性、数据安全性保护、数据库恢复。 2、什么是数据库系统? 答:在计算机系统上引入数据库技术就构成一个数据库系统(DataBase System ,DBS )。数据库系统是指带有数据库并利用数据库技术进行数据管理的计算机系统。DBS 有两个基本要素:一是DBS 首先是一个计算机系统;二是该系统的目标是存储数据并支持用户查询和更新所需要的数据。 3、简述数据库系统的组成。 答:数据库系统一般由数据库、数据库管理系统(及其开发工具)、数据库管理员(DataBase Administrator ,DBA )和用户组成。 4、试述数据库系统的三级模式结构。这种结构的优点是什么? 答:数据库系统的三级模式结构是指数据库系统是由外模式、模式和内模式三级构成,同时包含了二级映像,即外模式/模式映像、模式/内模式映像,如下图所示。 数据库应用1…… 外模式A 外模式B 模式 应用2应用3应用4应用5…… 模式 外模式/模式映像 模式/内模式映像 数据库系统的这种结构具有以下优点: (1)保证数据独立性。将外模式与模式分开,保证了数据的逻辑独立性;将内模式与模式分开,保证了数据的物理独立性。 (2)有利于数据共享,减少了数据冗余。 (3)有利于数据的安全性。不同的用户在各自的外模式下根据要求操作数据,只能对
