BW Table naming convention

Hello,

I find the following table naming conventions from the manuals BW systems

/BIx/E<InfoCube> - E Fact table

/BIx/F<InfoCube> - F Fact table

/BIx/D<InfoCube> - Dimension table

I have the following questions

1.Could you please let me know whether all the tables starting with '/BIx/D' will be dimension table only or there could be other tables ?

2. From the description field in SE11, I could not find the details for some of the tables.Please let me know whether there is any other way to identify the table type(Dimension,Fact..)

3. Also I would like to know the naming convention for aggregate tables.

Thanks,
