So, let’s get started to discuss DBMS and Traditional File System in detail. Then after, we will discuss the difference between them.

因此，让我们开始详细讨论DBMS和传统文件系统 。然后，我们将讨论它们之间的区别。

DBMS(数据库管理系统) (DBMS (Database Management System))

We have to know about what is data, database, and management first for knowing more about DBMS. So, Data is a collection of facts and figure that can be recorded; it can be in text, number, speech, video, image. Database means a huge amount of inter-related data is stored, retrieved and collect at one place in the database; In short, it is a collection of inter-related data stored in the database. Management is a collection of the program for security manage, retrieved and stored the data.

首先，我们必须先了解什么是数据，数据库和管理，以进一步了解DBMS。因此，数据是可以记录的事实和数字的集合；它可以是文字，数字，语音，视频，图像。数据库意味着在数据库中的一个位置存储，检索和收集大量相互关联的数据；简而言之，它是存储在数据库中的相互关联数据的集合。管理是用于安全管理，检索和存储数据的程序的集合。

After knowing about data, database and management you can assume that what is DBMS. So, Basically DBMS is a collection of interrelated data's stored in a database server; these data's will be stored in the form of tables. The aim of the database is to provide a way to store and retrieve database information in a fast and efficient manner. database system not only contains data's but it contains a complete definition or description of the database structure and constraints.

在了解了数据，数据库和管理之后，您可以假定什么是DBMS。因此，DBMS基本上是存储在数据库服务器中的相互关联数据的集合；这些数据将以表格形式存储。数据库的目的是提供一种以快速有效的方式存储和检索数据库信息的方法。数据库系统不仅包含数据，而且包含数据库结构和约束的完整定义或描述。

The first DBMS introduced by IBM in 1960's named Apollo (mission for moon). DB2 is the famous open source code (in which we can modify the code) and free source code (where code cannot be changed but, we can use it with its source code) database. EF-CODD (Father of RDBMS) was the first who describe database function and create a first latest version of the database; which follows their 11.5 rules in 12 rules which are known as 12 rules of EF-CODD.

IBM在1960年代推出的第一个DBMS名为Apollo(月球任务) 。 DB2是著名的开放源代码(可以在其中修改代码)和免费源代码(无法更改代码，但可以将其与源代码一起使用)数据库。 EF-CODD(RDBMS的父亲)是第一个描述数据库功能并创建数据库的第一个最新版本的人。它遵循12条规则中的11.5条规则，这些规则被称为EF-CODD的12条规则。

.minHeight{ min-height: 250px; } @media (min-width: 1025px){ .minHeight{ min-height: 90px; } } .minHeight{ min-height: 250px; } @media (min-width: 1025px){ .minHeight{ min-height: 90px; } }

传统文件系统 (Traditional File System)

Before the use of a computer, a manual file system was used to maintain the records and files. Data were stored and processed using a traditional file system and it makes it easy to find any information. In this traditional file system, each file is independent of other file and data in the different file can be integrated only by writing an individual program for each application. The data and application program that uses the data are arranged that any change to data requires modification of all the programs that use the data. Sometimes, it is not possible to identify all the programs using data and identified on trial and error basis. All functional areas in the organization create, processes its own files.

在使用计算机之前，使用了手动文件系统来维护记录和文件。数据是使用传统文件系统存储和处理的，因此可以轻松找到任何信息。在这种传统的文件系统中，每个文件都独立于其他文件，并且仅通过为每个应用程序编写一个单独的程序就可以集成不同文件中的数据。安排数据和使用该数据的应用程序，以使对数据的任何更改都需要修改所有使用该数据的程序。有时，不可能使用数据来识别所有程序，并且无法通过反复试验来识别。组织中的所有功能区域都创建，处理自己的文件。

The files such as inventory and payroll generate separate files and do not communicate with each other. The organization was simple to generate and had better local control but the data of an organization is dispersed throughout the functional subsystem.

库存和工资单等文件会生成单独的文件，并且不会相互通信。该组织易于生成并且具有更好的本地控制，但是组织的数据分散在整个功能子系统中。
