<div>DB support has advantage over flat file. entries can be accessed and processed faster. reduce read write I/O on disks. new web interfaces are much easier to build. and of course data report manipulations via db are more effective. although not all historical data kept in db you still have advantage with status / comments / retention etc.
</div>
<div>as far as i know db support is standard in the enterprise / smb programs like hpov / ca / tivoli. even whats up gold uses an internal db and not just flat file. we are using nagios 1.3 with db support and from our tests in larger enviroments the results are better with db support

<div>as for Nagios 2 it is bad that db support dropped. although you can achieve the functionality with Neb module (nagios-db) there is still the unnecessary write I/O of the status.log and im not sure it can be disabled.
