数据库的应用领域:

  • 多媒体数据库(这类数据库主要存储与多媒体相关的数据,如声音、图像和视频等数据。多媒体数据最大的特点是数据连续,而且数据量比较大,存储需要的空间较大)
  • 移动数据库(该类数据库是在移动计算机系统上发展起来的,如笔记本电脑、掌上计算机等。该数据库最大的特点是通过无线数字通信网络传输的。移动数据库可以随时随地地获取和访问数据,为一些商务应用和一些紧急情况带来了很大的便利)
  • 空间数据库(这类数据库目前发展比较迅速。它主要包括地理信息数据库(又称为地理信息系统,即GIS)和计算机辅助设计(CAD)数据库。其中地理信息数据库一般存储与地图相关的信息数据;计算机辅助设计数据库一般存储设计信息的空间数据库,如机械、集成电路以及电子设备设计图等)
  • 信息检索系统(信息检索就是根据用户输入的信息,从数据库中查找相关的文档或信息,并把查找的信息反馈给用户。信息检索领域和数据库是同步发展的,它是一种典型的联机文档管理系统或者联机图书目录)
  • 分布式信息检索(这类数据库是随着Internet的发展而产生的数据库。它一般用于因特网及远距离计算机网络系统中。特别是随着电子商务的发展,这类数据库发展更加迅猛。许多网络用户(如个人、公司或企业等)在自己的计算机中存储信息,同时希望通过网络使用发送电子邮件、文件传输、远程登录方式和别人共享这些信息。分布式信息检索满足了这一要求)
  • 专家决策系统(专家决策系统也是数据库应用的一部分。由于越来越多的数据可以联机获取,特别是企业通过这些数据可以对企业的发展作出更好的决策,以使企业更好地运行。由于人工智能的发展,使得专家决策系统的应用更加广泛)

Application areas of the database:

  • Multimedia database (this type of database mainly stores multimedia-related data, such as sound, image and video data. The biggest feature of multimedia data is continuous data, and the amount of data is relatively large, and the storage space required is large)
  • Mobile database (this type of database is developed on mobile computer systems, such as notebook computers, palmtop computers, etc.. The biggest feature of this database is that it is transmitted through a wireless digital communication network. The mobile database can obtain and access data anytime, anywhere, Brings great convenience to some business applications and some emergencies)
  • Spatial databases (this type of database is currently developing rapidly. It mainly includes geographic information databases (also known as geographic information systems, or GIS) and computer-aided design (CAD) databases. Geographic information databases generally store map-related information data ; Computer-aided design database generally stores the spatial database of design information, such as mechanical, integrated circuit and electronic equipment design drawings, etc.)
  • Information retrieval system (information retrieval is to find relevant documents or information from the database according to the information entered by the user, and feed the searched information back to the user. The field of information retrieval and the database are developed simultaneously, and it is a typical online Document management system or online book catalog)
  • Distributed information retrieval (This type of database is a database produced with the development of the Internet. It is generally used in the Internet and long-distance computer network systems. Especially with the development of e-commerce, this type of database has developed more rapidly. Many Network users (such as individuals, companies or enterprises, etc.) store information on their computers, and at the same time hope to use the network to send e-mails, file transfers, and remote login methods to share this information with others. Distributed information retrieval meets this requirement)
  • Expert decision-making system (Expert decision-making system is also part of the database application. As more and more data can be obtained online, in particular, enterprises can make better decisions on the development of the enterprise through these data, so that the enterprise can run better. Due to the development of artificial intelligence, the application of expert decision-making systems has become more extensive)
