During the physical design process, you convert the data gathered during the logical design phase into a description of the physical database structure. The physical design of the database specifies the physical configuration of the database on the storage media. It is the process of making a description of the execution of the database on secondary storage, which describes the base relations, file organizations as well as indexes used to gain efficient access to the data and any associated integrity constraints and security measures.
