What are the common features of a Database Management System?

The database is a collection of related data, which is a collection of facts and figures for the production of information. These databases are extremely configurable and are available. A database management system stores data so that information can easily be retrieved, manipulated and produced.

Features of DBMS The modern-day DBMS has the following featuresReal-world entity- A modern-day DBMS is more realistic in designing its architecture using real- world entities. It also uses behaviour and attributes. A school database, for example, can use students as an entity and their age as an attribute.

Data & application isolation- A database is an active entity, while the data on which the database works and organizes is said to be passive. DBMS also stores data- based metadata in order to facilitate its own process.

Relation-based tables: DBMS enables tables to be formed by entities and relationships. A user can understand the database architecture only by viewing the names of the table.

Consistency: Consistency is a state in which all relationships are kept in a database remains the same. The existing methods and techniques can detect attempt to leave inconsistent database. A DBMS can supply greater consistency than earlier data storage systems like fileprocessing applications.

Less Redundant: DBMS follows the normalization rules that divide a relationship when any of its attributes is redundant in values. Normalisation is a mathematically rich and scientific process, which reduces redundancy of information.

ACID properties: DBMS follows ACID (atomicity, consistency, isolation and durability) concepts. These are applicable to transactions that manipulate data in a database. ACID properties help to keep the database healthy in multi-transactional setting and in case of failures.

Multiple Views: For different users, DBMS offers multiple views. A user in the department of sales will have a different view of the database than a person in the department of production. This feature allows users to view the database in a concentrated manner as required.

Query Language: DBMS has a query language that makes retrieving and manipulating data more efficient. A user can use as many and as many filtering options as necessary to obtain a data set. Where file processing system was used, it was not traditionally possible.

Security: DBMS offers a wide range of security features that allow multiple users to see different features. A user in the sales department, for example, can not see the data belonging to the purchasing department. Since a DBMS is not saved as traditional file systems on the disk, miscreants cannot break the code easily.
