Data Models in DBMS

Exploring Hierarchical, Network, Relational, and Object-Oriented Models

Traditional data models include Hierarchical (tree structure with parent-child relationships), Network (graph with many-to-many links), and Relational (tables with keys for querying). Modern models feature Object-Oriented (classes and objects with methods), but Relational remains the most widely used due to its simplicity, flexibility, and SQL support.

DBMS operations rely on key languages like DDL for defining data structures (CREATE, ALTER), DML for manipulating data (INSERT, UPDATE, DELETE), and DCL for controlling access (GRANT, REVOKE). SQL serves as the standard query language for all these DBMS operations.

DBMS Operations & Languages

• DDL: Data Definition Language (CREATE, ALTER)
• DML: Data Manipulation Language (INSERT, UPDATE, DELETE)
• DCL: Data Control Language (GRANT, REVOKE)
• SQL: Standard query language for DBMS operations
