Introduction to DBMS
A Database is an organized collection of related data. The data is typically organized to model relevant aspects of reality. Database systems constitute the most important component of any computer-based information system.
Architecture and Languages
In a DBMS, data must be structured, organized, and managed efficiently. To understand its internal workings, we look at the schemas, instances, overall architecture, and the users who interact with it.
Data Models
Data models are a collection of conceptual tools for describing data schemas, data relationships, and constraints. They dictate the overarching structure of how databases store and correlate entities.
