around and mapped the stuff that Solr does into database tables, you would lose all of the
performance advantages that the Lucene/Solr design brings to the table.  There would be no

I think this is just a matter of having been "brainwashed" into thinking that a database is

SOLR will keep the indexed information in directory called
index(${DATA_DIR}/index) after clicking the commit from admin console and
also we can override  the existing index files.similarly can we keep (or) 
store these  index related information in permanent location like db table
rather than a file system?
