Answer / nadia sheikh
Logical Views allows application architects to create any
desired view using MicroStrategy, without DBA involvement.
Once these Logical views are created, they are available to
the report designer in a way similar to any other table.
This allows developers to model attributes and facts whose
expressions span multiple tables.

Well both answers are right( from tiru and nadia) same thing just differ in approach.
EX: if there is any table with such feilds
say
day_id, Qtr_id, Qtr_desc, Month_id, Month_desc.
2nd table sales
001 ...090 has same sales ..say 100
now if you are calculating sales over day
it will return you wrong data, by doing 90 days *100 sales values (this is termed as multiple counting problem)
so here we developer are facilitate by this logical table object. we create a new table with proper qtr_id and qtr_desc with sales to get the accurate data every time.
Which will thus be called as aggregated sales data.
This is not recommended until and unless you dont find any other way since performance is your high priority.
