Physical file (PF) contains the data and have only one
record format. Logical file (LF) is a view of the physical
file which does not contain any data may be based on one
physical file or more then one physical file. Logical file
can have more then one record format. Logical can be non
join or join logical file. Performance becomes better if
you use the logical file in the program.
