database英文写作篇2

A database consists of an organized collection of data for one or more uses,typically in digital form.One way of classifying databases involves the type of their contents,for example:bibliographic,document-text,statistical.Digital databases are managed using database management systems,which store database contents,allowing data creation and maintenance,and search and other access.

Database architecture consists of three levels,external,conceptual and internal.Clearly separating the three levels was a major feature of the relational database model that dominates 21st century databases.

The external level defines how users understand the organization of the data.A single database can have any number of views at the external level.The internal level defines how the data is physically stored and processed by the computing system.Internal architecture is concerned with cost,performance,scalability and other operational matters.The conceptual is a level of indirection between internal and external.It provides a common view of the database that is uncomplicated by details of how the data is stored or managed,and that can unify the various external views into a coherent whole.

Database介绍

Database是按照数据结构来组织、存储和管理数据的仓库，它产生于距今六十多年前，随着信息技术和市场的发展，特别是二十世纪九十年代以后，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。数据库有很多种类型，从最简单的存储有各种数据的表格到能够进行海量数据存储的大型数据库系统都在各个方面得到了广泛的应用。

在信息化社会，充分有效地管理和利用各类信息资源，是进行科学研究和决策管理的前提条件。数据库技术是管理信息系统、办公自动化系统、决策支持系统等各类信息系统的核心部分，是进行科学研究和决策管理的重要技术手段。[1]

数据库，顾名思义，是存入数据的仓库。只不过这个仓库是在计算机存储设备上的，而且数据是按一定格式存放的。

当人们收集了大量的数据后，应该把它们保存起来进行进一步的处理，进一步的抽取有用的信息。当年人们把数据存放在文件柜中，可现在随着社会的发展，数据量急剧增长，现在人们就借助计算机和数据库技术科学的保存大量的数据，以便能更好的利用这些数据资源。

要是下定义的话，就应该是：指长期储存在计算机内的、有组织的、可共享的数据集合。

数据库包含关系数据库、面向对象数据库及新兴的XML数据库等多种，目前应用最广泛的是关系数据库，若在关系数据库基础上提供部分面向对象数据库功能的对象关系数据库。在数据库技术的早期还曾经流行过层次数据库与网状数据库，但这两类数据库目前已经极少使用。
