What is Database?

A Database is a collection of information and data that is unified so that it can be easily accessed, managed, delete and updated in Database.




The database is unified into rows, columns, and tables, and it is indexed to make it easier to find proper information and data about the object. Data gets updated, expanded and deleted as new information and data is added. Databases process workloads to create and update and delete themselves, querying the data they contain and running applications against it.

What is a Database Management System (DBMS)?

Kinds of Database Management System (DBMS)?

There are Four Main DBMS below I am mentioning that all.

Hierarchical DBMS
A hierarchical DBMS is a data model in which the data is organized into a tree-like structure. The data is stored as records which are connected to one another through links. A record is a collection of fields, with each field containing only one value.




Network DBMS
A network model is a database model that is designed as a flexible approach to representing objects and their relationships. A unique feature of the network model is its schema, which is viewed as a graph where relationship types are arcs and object types are nodes.

Relational DBMS
A relational database is a collection of data items organized as a set of formally-described tables from which data can be accessed or reassembled in many different ways without having to reorganize the database tables.

Object-Oriented Relation DBMS
An object database is a database management system in which information is represented in the form of objects as used in object-oriented programming. Object databases are different from relational databases which are table-oriented Object databases have been considered
