    1简介

    编辑本段 回目录

    数据库,简单来说是本身可视为电子化的文件柜——存储电子文件的处所,用户可以对文件中的数据进行新增、截取、更新、删除等操作。

    数据库指的是以一定方式储存在一起、能为多个用户共享、具有尽可能小的冗余度、与应用程序彼此独立的数据集合。在经济管理的日常工作中,常常需要把某些相关的数据放进这样的“仓库”,并根据管理的需要进行相应的处理。

    2发展历史

    编辑本段 回目录

    数据库的历史可以追溯到五十年前,那时的数据管理非常简单。通过大量的分类、比较和表格绘制的机器运行数百万穿孔卡片来进行数据的处理,其运行结果在纸上打印出来或者制成新的穿孔卡片。而数据管理就是对所有这些穿孔卡片进行物理的储存和处理。然而,1950 年雷明顿兰德公司(Remington Rand Inc)的一种叫做Univac I 的计算机推出了一种一秒钟可以输入数百条记录的磁带驱动器,从而引发了数据管理的革命。1956 年IBM生产出第一个磁盘驱动器—— the Model 305 RAMAC。此驱动器有50 个盘片,每个盘片直径是2 英尺,可以储存5MB的数据。使用磁盘最大的好处是可以随机存取数据,而穿孔卡片和磁带只能顺序存取数据。

    1970年,IBM的研究员E.F.Codd博士在刊物《Communication of the ACM》上发表了一篇名为“A Relational Model of Data for Large Shared Data Banks”的论文,提出了关系模型的概念,奠定了关系模型的理论基础。尽管之前在1968年Childs已经提出了面向集合的模型,然而这篇论文被普遍认为是数据库系统历史上具有划时代意义的里程碑。Codd的心愿是为数据库建立一个优美的数据模型。后来Codd又陆续发表多篇文章,论述了范式理论和衡量关系系统的12条标准,用数学理论奠定了关系数据库的基础。关系模型有严格的数学基础,抽象级别比较高,而且简单清晰,便于理解和使用。但是当时也有人认为关系模型是理想化的数据模型,用来实现DBMS是不现实的,尤其担心关系数据库的性能难以接受,更有人视其为当时正在进行中的网状数据库规范化工作的严重威胁。为了促进对问题的理解,1974年ACM牵头组织了一次研讨会,会上开展了一场分别以Codd和Bachman为首的支持和反对关系数据库两派之间的辩论。这次著名的辩论推动了关系数据库的发展,使其最终成为现代数据库产品的主流。

    1976年霍尼韦尔公司(Honeywell)开发了第一个商用关系数据库系统——Multics Relational Data Store。关系型数据库系统以关系代数为坚实的理论基础,经过几十年的发展和实际应用,技术越来越成熟和完善。其代表产品有Oracle、IBM公司的 DB2、微软公司的MS SQL Server以及Informix、ADABAS D等等。

    1986年,ANSI把SQL作为关系数据库语言的美国标准,同年公布了标准SQL文本。SQL标准有3个版本。基本SQL定义是ANSⅨ3135-89,“Database Language - SQL with Integrity Enhancement”[ANS89],一般叫做SQL-89。SQL-89定义了模式定义、数据操作和事务处理。SQL- 89和随后的ANSⅨ3168-1989,“Database Language-Embedded SQL”构成了第一代SQL标准。ANSⅨ3135-1992[ANS92]描述了一种增强功能的SQL,叫做SQL-92标准。SQL-92包括模式操作,动态创建和SQL语句动态执行、网络环境支持等增强特性。在完成SQL-92标准后,ANSI和ISO即开始合作开发SQL3标准。SQL3的主要特点在于抽象数据类型的支持,为新一代对象关系数据库提供了标准。

    二十世纪九十年代,随着基于PC的客户/服务器计算模式和企业软件包的广泛采用,数据管理的变革基本完成。数据管理不再仅仅是存储和管理数据,而转变成用户所需要的各种数据管理的方式。Internet的异军突起以及XML语言的出现,给数据库系统的发展开辟了一片新的天地。

    3特点

    编辑本段 回目录

    ⑴ 实现数据共享

    数据共享包含所有用户可同时存取数据库中的数据,也包括用户可以用各种方式通过接口使用数据库,并提供数据共享。

    ⑵ 减少数据的冗余度

    同文件系统相比,由于数据库实现了数据共享,从而避免了用户各自建立应用文件。减少了大量重复数据,减少了数据冗余,维护了数据的一致性。

    ⑶ 数据的独立性

    数据的独立性包括逻辑独立性(数据库中数据库的逻辑结构和应用程序相互独立)和物理独立性(数据物理结构的变化不影响数据的逻辑结构)。

    ⑷ 数据实现集中控制

    文件管理方式中,数据处于一种分散的状态,不同的用户或同一用户在不同处理中其文件之间毫无关系。利用数据库可对数据进行集中控制和管理,并通过数据模型表示各种数据的组织以及数据间的联系。

    ⑸数据一致性和可维护性,以确保数据的安全性和可靠性

    ⑹ 故障恢复

    由数据库管理系统提供一套方法,可及时发现故障和修复故障,从而防止数据被破坏。数据库系统能尽快恢复数据库系统运行时出现的故障,可能是物理上或是逻辑上的错误。比如对系统的误操作造成的数据错误等。

    4结构

    编辑本段 回目录

    数据库的基本结构分三个层次,反映了观察数据库的三种不同角度。

    以内模式为框架所组成的数据库叫做物理数据库;以概念模式为框架所组成的数据叫概念数据库;以外模式为框架所组成的数据库叫用户数据库。

    ⑴ 物理数据层。

    它是数据库的最内层,是物理存贮设备上实际存储的数据的集合。这些数据是原始数据,是用户加工的对象,由内部模式描述的指令操作处理的位串、字符和字组成。

    ⑵ 概念数据层。

    它是数据库的中间一层,是数据库的整体逻辑表示。指出了每个数据的逻辑定义及数据间的逻辑联系,是存贮记录的集合。它所涉及的是数据库所有对象的逻辑关系,而不是它们的物理情况,是数据库管理员概念下的数据库。

    ⑶ 用户数据层。

    它是用户所看到和使用的数据库,表示了一个或一些特定用户使用的数据集合,即逻辑记录的集合。

    数据库不同层次之间的联系是通过映射进行转换的。
