What is DBMS?
A software program used to construct, maintain, and administer databases is known as a database management system (DBMS). A database is a collection of data organized in a specific way, allowing it to be easily accessed, updated, and queried.
A DBMS provides several vital functions, including:
Data definition: This refers to the ability to create and change the structure of a database, including the description of tables, fields, and relationships.
Data manipulation refers to the ability to insert, delete, and modulate data in a database.
Data security refers to the ability to protect a database from unauthorized access or modification.
Data query refers to the ability to retrieve and view data from a database using specific criteria.
DBMSs are used in many applications and are essential for managing and organizing large amounts of data. Examples of DBMSs include MySQL, Oracle, and Microsoft SQL Server.
Data models, database distributions, user counts, and other factors can all be used to categorize database management systems. The most popular are relational, distributed, hierarchical, object-oriented, and network DBMS software types.
The database management system that is distributed:
A distributed database management system (DBMS) is a collection of logically connected databases dispersed across a network and controlled by a single database application. This kind of DBMS synchronizes data regularly and ensures that any data changes are updated across the board in the database.
Database management system with a hierarchy:
Model data is organized in a tree-like pattern using hierarchical databases. A parent-child connection is used to describe data storage and can be top-down or bottom-up.
Database management system for networks:
The network database approach allows each child to have several parents, addressing the requirement for more complicated relationships. Entities are arranged in a graph that has multiple pathways leading to them.
Database management system for relationships:
Because of their user-friendly interface, relational database management systems (RDBMS) are the most widely used data model. It is based on normalizing the data in the table’s rows and columns. Therefore, when you require a data storage system that is scalable, adaptable, and able to manage a lot of information, this is a suitable alternative.
Database management system with objects:
Instead of using rows and columns to hold data, object-oriented models use objects. Based on object-oriented programming (OOP), enables things to contain members like fields, properties, and methods.
