The physical data independence is basically used to separate conceptual levels from the internal/physical levels. All three are somewhat in line but in practice we still see people mix-and-match between abstraction levels. What is the difference between a repeated measures design and an independent groups design? In that case, conceptual/logical appears to map on the architecture level, whereas physical seems to map on the design/ implementation level. 2.Logical database modeling does not include indexes and constraints; the logical database model for an application can be used across various database software and implementations; whereas physical database modeling is software and hardware specific and has indexes and constraints.
