Managing Databases And Their Categories管理数据库和他们各自的领域里
Data bases are used in all kinds of businesses and it is important that they are kept running as efficiently as possible.资料库中使用的各类企业和重要的是，他们一直运行尽可能有效。 That is where data base management comes into play.这就是数据库管理发挥作用。 Many data base managing systems, which are software that aid in organizing, obtaining information from and putting data into data bases, are designed to work with specific data base models.许多数据库管理系统，这是软件，援助组织，获取信息，并把数据转换成数据库，目的是与特定的数据库模式。 A well-built database management system (DBMS) can be used for almost all of a company's database information.完善的内置数据库管理系统（ DBMS ）可用于几乎所有的公司的数据库信息。 They can run on personal computers, for personal uses, or on giant mainframes that control all of a company's database.它们可以运行在个人电脑上，用于个人用途，或在大型主机，控制所有的公司的数据库。 There are many types of data base management systems and most places with computers will use some form of one.有许多类型的数据库管理系统和大多数地方的计算机将使用某种形式的一种。 Example database management software includes computerized library systems, flight reservation systems, and computerized inventory systems.例如数据库管理软件，包括电脑化图书馆系统，航班预定系统，和电脑库存系统。 Even an email client's address book is a type of database management system.即使一个电子邮件客户端的地址簿是一种数据库管理系统。 Basically a data base will store information in a series of columns and rows known as a table.基本上是一个数据基地将信息存储在一系列栏和列被称为表。 When a particular piece of data needs to be retrieved, the data base system will use pointers to find that piece of data and bring it forward to be used.当一个特定的数据需要检索，数据的基础系统将使用指针发现一块数据，并使其能使用。 There are many applications for database management systems, including accounting work, engineering work, and bibliographic work.有许多应用数据库管理系统，包括会计的工作，工程，和书目工作。 A data base management system can be used with several different categories of databases, based on how the data is stored. The six major categories of databases are the following:资料库管理系统可以使用几种不同类别的数据库的基础上，如何在数据存储。六个大类的数据库如下： - Flat model平板模式
- Hierarchical model层次模型
- Network model网络模型
- Relational model关系模型
- Dimensional model三维模型
- Object database model对象数据库模型
The flat model is the simply category and is essentially a table or a matrix for data. The hierarchical model organizes data into a tree-like structure and allows a 1:N relationship between types of data.平坦模式是简单分类和本质上是一个表或矩阵的数据。层次模型的数据组织成一个树形结构，使1 ：无关系类型的数据。 The network model is similar to the hierarchical model, only it is capable of larger relationships between types of data and allowing pointers to flow between data more efficiently based upon these relationships.该网络模型类似层次模型中，只有它能够在更大的关系类型的数据，并允许指针之间流动的数据更有效地根据这些关系。 The relational model uses relations, attributes, and domains to organize data based on multiple tables. The dimensional model is a mixture of several types of database categories.关系模型利用关系，属性，和域，组织数据的基础上多桌。的三维模型是一种混合的几种类型的数据库类。 It primarily uses a table format that is described using dimensions, but it also follows a hiearchical structure.它主要采用了表格式，使用方面的描述，但它也遵循hiearchical结构。 Finally the object database model uses object-oriented programming techniques to store and manipulate data. It is becoming one of the most popular types of databases used and it helps bring database applications and programming applications closer together.最后的对象数据库模型使用面向对象的编程技术来存储和处理数据。这是成为最常用的数据库使用和有利于实现数据库应用和编程应用的关系更加紧密。 A company should not just stick with one database model, however. Using multiple models for different types of data is a great way to keep things organized and easy to access.公司不应该仅仅坚持一个数据库模型，但是。使用多种型号的不同类型的数据是一个伟大的方式以保证系统的组织和容易获得。 Terms >> Contact >> Privacy Policy And Terms Of Use 条款 “ ” 联系方式 “ ” 隐私政策和使用条件 |
