Get a syslog-ng up && running. 
Create filter to match only entries you are interested in ( iptables 
--log-prefix "something-unique"  + filter { } definition in syslog-ng.conf )
Try to catch this "prefix" and direct it into pipe ( you can feed some SQL 
backend with it or write small daemon/script that will read this pipe line by 
line and extract information that you want to store/you are interested in ).

And also try NOT to log netfilter messages info messages/kernel and so on 
( performance reasons ).  This can be achived by using "not 
match(somestring)" in log {} section.
