Hi Tamas,

These are good questions, expect the FAQ to include these answers soon!

I'll see if I can add anything to Yves reply :)

MySQL uses many table types.  The most advances is InnoDB tables. 
(Although not quite the fastest).  I chose these because they offer 
significant advantages:

- Referential Integrity.
- Transactions.
- Concurrent Backup.

These protect the database from corruption.  For instance if a program 
crashes.  They also bind the data together.  You cannot, for instance, 
delete a 'host' if there is still valid data for this host.  Therefore 
avoiding hundreds of meg of data you cannot see or delete without 
specialist coding :)

They also offer concurrent backup.  'Hot Backups'.  You can dump the 
contents of the database without stopping PP.  Even if that dump takes 
many days, you always get a snapshot of how the database was at the 
start of the backup.

More information on InnoDB tables from http://www.innodb.com.


> 6. How PerfParse graph "data", if there is no data?

Any plugin not providing valid graphable (performance) data will not be 
shown to select.  In the future we may change this to list all 
host/service but mark them as containing no data.  If the users wish this :)
