DBMS and Traditional file system have some advantages, disadvantages, applications, functions, features, components and uses. So, in this article, we will discuss these differences, advantages, disadvantages and many other things. If you have any doubt, feel free to ask in the comment section.

DBMS和傳統(tǒng)文件系統(tǒng)具有一些優(yōu)點(diǎn)，缺點(diǎn)，應(yīng)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(yōu)點(diǎn)，缺點(diǎn)和許多其他事情。 如有任何疑問(wèn)，請(qǐng)隨時(shí)在評(píng)論部分提問(wèn)。

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(kāi)始詳細(xì)討論DBMS和傳統(tǒng)文件系統(tǒng) 。 然后，我們將討論它們之間的區(qū)別。

DBMS(數(shù)據(jù)庫(kù)管理系統(tǒng)) (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(shù)據(jù)，數(shù)據(jù)庫(kù)和管理，以進(jìn)一步了解DBMS。 因此，數(shù)據(jù)是可以記錄的事實(shí)和數(shù)字的集合； 它可以是文字，數(shù)字，語(yǔ)音，視頻，圖像。 數(shù)據(jù)庫(kù)意味著在數(shù)據(jù)庫(kù)中的一個(gè)位置存儲(chǔ)，檢索和收集大量相互關(guān)聯(lián)的數(shù)據(jù)； 簡(jiǎn)而言之，它是存儲(chǔ)在數(shù)據(jù)庫(kù)中的相互關(guān)聯(lián)數(shù)據(jù)的集合。 管理是用于安全管理，檢索和存儲(chǔ)數(shù)據(jù)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(shù)據(jù)，數(shù)據(jù)庫(kù)和管理之后，您可以假定什么是DBMS。 因此，DBMS基本上是存儲(chǔ)在數(shù)據(jù)庫(kù)服務(wù)器中的相互關(guān)聯(lián)數(shù)據(jù)的集合； 這些數(shù)據(jù)將以表格形式存儲(chǔ)。 數(shù)據(jù)庫(kù)的目的是提供一種以快速有效的方式存儲(chǔ)和檢索數(shù)據(jù)庫(kù)信息的方法。 數(shù)據(jù)庫(kù)系統(tǒng)不僅包含數(shù)據(jù)，而且包含數(shù)據(jù)庫(kù)結(jié)構(gòu)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(gè)DBMS名為Apollo(月球任務(wù)) 。 DB2是著名的開(kāi)放源代碼(可以在其中修改代碼)和免費(fèi)源代碼(無(wú)法更改代碼，但可以將其與源代碼一起使用)數(shù)據(jù)庫(kù)。 EF-CODD(RDBMS的父親)是第一個(gè)描述數(shù)據(jù)庫(kù)功能并創(chuàng)建數(shù)據(jù)庫(kù)的第一個(gè)最新版本的人。 它遵循12條規(guī)則中的11.5條規(guī)則，這些規(guī)則被稱為EF-CODD的12條規(guī)則。

傳統(tǒng)文件系統(tǒng) (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(jì)算機(jī)之前，使用了手動(dòng)文件系統(tǒng)來(lái)維護(hù)記錄和文件。 數(shù)據(jù)是使用傳統(tǒng)文件系統(tǒng)存儲(chǔ)和處理的，因此可以輕松找到任何信息。 在這種傳統(tǒng)的文件系統(tǒng)中，每個(gè)文件都獨(dú)立于其他文件，并且僅通過(guò)為每個(gè)應(yīng)用程序編寫一個(gè)單獨(dú)的程序就可以集成不同文件中的數(shù)據(jù)。 安排數(shù)據(jù)和使用該數(shù)據(jù)的應(yīng)用程序，以使對(duì)數(shù)據(jù)的任何更改都需要修改所有使用該數(shù)據(jù)的程序。 有時(shí)，不可能使用數(shù)據(jù)來(lái)識(shí)別所有程序，并且無(wú)法通過(guò)反復(fù)試驗(yàn)來(lái)識(shí)別。 組織中的所有功能區(qū)域都創(chuàng)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(kù)存和工資單等文件會(huì)生成單獨(dú)的文件，并且不會(huì)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(shù)據(jù)分散在整個(gè)功能子系統(tǒng)中。
