DBMS和傳統文件系統具有一些優點，缺點，應用程序，功能，特性，組件和用途。 因此，在本文中，我們將討論這些差異，優點，缺點和許多其他事情。 如有任何疑問，請隨時在評論部分提問。

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，讓我們開始詳細討論DBMS和傳統文件系統 。 然后，我們將討論它們之間的區別。

DBMS(數據庫管理系統) (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，我們必須先了解什么是數據，數據庫和管理，以進一步了解DBMS。 因此，數據是可以記錄的事實和數字的集合； 它可以是文字，數字，語音，視頻，圖像。 數據庫意味著在數據庫中的一個位置存儲，檢索和收集大量相互關聯的數據； 簡而言之，它是存儲在數據庫中的相互關聯數據的集合。 管理是用于安全管理，檢索和存儲數據的程序的集合。

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.

在了解了數據，數據庫和管理之后，您可以假定什么是DBMS。 因此，DBMS基本上是存儲在數據庫服務器中的相互關聯數據的集合； 這些數據將以表格形式存儲。 數據庫的目的是提供一種以快速有效的方式存儲和檢索數據庫信息的方法。 數據庫系統不僅包含數據，而且包含數據庫結構和約束的完整定義或描述。

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年代推出的第一個DBMS名為Apollo(月球任務) 。 DB2是著名的開放源代碼(可以在其中修改代碼)和免費源代碼(無法更改代碼，但可以將其與源代碼一起使用)數據庫。 EF-CODD(RDBMS的父親)是第一個描述數據庫功能并創建數據庫的第一個最新版本的人。 它遵循12條規則中的11.5條規則，這些規則被稱為EF-CODD的12條規則。

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

傳統文件系統 (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.

在使用計算機之前，使用了手動文件系統來維護記錄和文件。 數據是使用傳統文件系統存儲和處理的，因此可以輕松找到任何信息。 在這種傳統的文件系統中，每個文件都獨立于其他文件，并且僅通過為每個應用程序編寫一個單獨的程序就可以集成不同文件中的數據。 安排數據和使用該數據的應用程序，以使對數據的任何更改都需要修改所有使用該數據的程序。 有時，不可能使用數據來識別所有程序，并且無法通過反復試驗來識別。 組織中的所有功能區域都創建，處理自己的文件。

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.

庫存和工資單等文件會生成單獨的文件，并且不會相互通信。 該組織易于生成并且具有更好的本地控制，但是組織的數據分散在整個功能子系統中。
