PHYSICAL DBMS ARCHITECTURE
The physical architecture defines the software components used to process and enter data, and how these software components are related and interconnected. Though it is not possible to simplify the component structure of a DBMS, it is possible to recognize a number of key functions which are similar to most database management systems. The components that normally execute these functions are shown in Figure , which depicts the physical architecture of a typical DBMS.
