Answer / pratap thakur

The physical file you are working with very large, creating and using a logical file will allow an application to perform faster than using an open query file.Since access paths created by open query files are temporary, applications that use an access path frequently will be more efficient using a logical file, since the access path will not have to be rebuilt every time the file is open.

A phisical file has two fields like 1) Account No(10,0) 2)Phone No(15,0)Unique on both fields?Please give me the answer for this?
