The transparent DBMS is a type of DBMS which keeps its physical structure hidden from users. Physical structure or physical storage structure implies to the memory manager of the DBMS, and it describes how the data stored on disk.

A transparent DBMS (Database Management System) is one that provides a seamless interface to users and applications, hiding the complexities of data storage, retrieval, and management. In other words, users interact with the database system as if it were a single entity, without needing to be aware of the underlying structures or processes. This transparency typically extends to aspects such as data distribution, replication, and transaction management, allowing users to focus on their tasks rather than the intricacies of the database system.
