Quizplus · Accepted Answer

Physical database design techniques can involve decisions on data storage structures, indexing, and partitioning, which directly impact the way data is stored on disk. These decisions can alter the logical design to better meet performance and storage requirements. However, other physical design techniques such as database normalization do not change the logical structure of the database, but rather aim to eliminate redundancy and improve data integrity.
