select from 6 table into internal table

hi,

i want to fetch datas from 6 tables to be displayed in one list or grid display.

In which 3 of the tables share a common field and other 3 doesnt relate each other.

Then to use 3 select statements to append in to 3 new internal table using for all entries.

can some one help me out?
