The Structure of a Database Management System and its advantages

Hi

A DBMS has a structure with three levels: Internal Level, Logical Level, and External/ View Level. The DBMS three-level structure is what makes the DBMS system essential. This structure is responsible for providing the advantages of the DBMS that we receive. Data security is the main plus point of all, and is incorporated in the view level with the help of a concept called as DATA ABSTRACTION. Another name for this structure is the three-tier structure because there are three stages in this system architecture.
