Every organisation has their large amounts of data in their database. A database management system (DBMS) is a software tool that organises those data in a database and we have experts of DBMS Assignment help by over IT or Database Experts.
A DBMS consists of three elements which are given below:
The physical database: It is the collection of files that consist of the data.
The database engine: It is a software that makes possible to connect and alter the contents of the database.
The database scheme: It is the requirement of the logical structure of the data stored in the database.
It can be divided into four components which are mentioned below:
Users: Users may vary like DB administrator, System developer and End users.
Database application: It can be Personal, Departmental, Enterprise and Internal
DBMS : Software that grants users to specify, produce and organises database access, Ex: MySql, Oracle etc.
Database: It is a set of logical data.
This DBMS has numerous number of merits as compared to traditional computer file processing approach.
Some advantages of DBMS are given below:
1. Controlling Data Redundancy:
In traditional computer file processing or non-database systems, every application program has its own files. It is quite feasible in case of DBMS, all the data of an organisation is accumulated into a single database and cannot be duplicated.
2. Data Consistency:
If the DBMS has decreased redundancy to a least level, the database system imposes consistency. It implies that when a data item exists numerous times in the database and is updated, the DBMS repeatedly updates every occurrence of a data item in the database.
3. Data Sharing:
In this system, data can be shared by allowed users of the company. It manages the data and allow the users to access the data. Many users can be allowed to access the same set of information at the same time. The distant users can also share the same data. Also, the data of same database can be shared between various application programs.
4. Data Integration:
In this management system, data in database is stored in tables. A single database consists of multiple tables and relationships can be built between tables or related data entities. It enables easier data retrieve and update of the data.
There are other various advantages of DBMS which helps in easier data management in an organisation.
