In order understand these questions u should be clear with BW star schema

1.We store characteristics in master data tables

2.for earch and every dimid system will generate a sid in the sid table which is uniquely identified by system through this sid concept it links up dimid with master data table.

3.yes it is possible to have characteristics with no master data.(EG line item dimension)

4.dimension attribute is nothing but the characteristics infoobject,

but i am not sure about described attribute as i've not heard of it.
