Research On The Decision Support System Of Smart Government Based On Data Warehouse [PDF]
, 2016 在电子政务阶段，我国已经开始利用计算机技术建设决策支持系统以辅助政府决策，使政府从主观、经验式的传统决策向靠数据说话、用数据决策的电子政务决策发展。随着电子政务的不断发展，政府业务内容和业务能力的不断提升，电子政务系统中聚集了海量数据，除了以结构化数据为主体，还包括半结构化、非结构化的数据。在此基础上，电子政务决策支持系统尤其是其核心技术数据仓库已经无法满足政府的业务需求。近年来，随着“智慧城市”、“互联网+”、“云计算”、“大数据”等概念的不断推出 ...

Research on The Construction of Archives Big Data from The Perspective of National Governance [PDF]
, 2016 摘要 当前，大数据已成为国家的重大战略，大数据资源和技术成为国与国之间竞争的高地。国际上曾有人将大数据比作“未来的石油”，但相比而言，石油是不可再生的资源，而数据却是源源不断，拥有无限潜力的资源。 大数据时代，政府已成为最大的数据生产者和拥有者，而政府的档案部门（包括各类机关档案室、部门档案馆、专业档案馆和综合档案馆等）则是政府部门中最大的数据集散地。从法定职责来说，各单位、组织的数据最终要归于档案部门。而且，由于数据的原始性、完整性、权威性、长期保存性以及档案部门相对中立的机构特性等 ...
