In the CREATE TABLE statement, the PHYSICAL clause is used to point to the physical location of the raw data file. This PHYSICAL clause can contain a relative path name (relative to the location of the Omnidex Environment File) such as "dat/states.dat", or an absolute path name such as "d:/class/lab1/dat/states.dat".
