The database system is divided into three components: Query Processor, Storage Manager, and Disk Storage. These are explained as following below. 1. Query Processor: It interprets the requests (queries) received from end user via an application program into instructions.

The structure of a Database Management System (DBMS) can be divided into three main components: the Internal Level, the Conceptual Level, and the External Level. Internal Level: This level represents the physical storage of data in the database.
Structure of DBMS:
- DBMS (Database Management System) acts as an interface between the user and the database. The user requests the DBMS to perform various operations such as insert, delete, update and retrieval on the database.
The
database schemais the structure of a databasedescribed in a formal languagesupported typically by a relational database management system(RDBMS). The term "schema" refers to the organization of data as a blueprint of how the database is constructed (divided into database tables in the case of relational databases).In DBMS, the
3-tier architecture is a client-server architecture that separates the user interface, application processing, and data management into three distinct tiers or layers. The 3-tier architecture is widely used in modern web applications and enterprise systems because it offers scalability, flexibility, and security.,

- The Internal Level: This level represents the physical storage of data in the database.
- The Conceptual Level: This level represents the logical structure of the database.
