#TODO: why no size.log?? always error!!!

#in some system, maybe /usr/bin/ instead of /bin/
#according executables to deal with dbms
#NOTICE: require that virtuoso-openlink/openrdf-sesame/apache-jena is installed and gstore(single mode) is compiled!

#WARN:test gstore, jena, virtuoso with lubm, bsbm, watdiv, dbpedia
#when testing sesame and others, just use bsbm and watdiv because format in lubm
#i snot supported by sesame(invalid IRI), and dbpedia may be too large

#NOTICE+WARN:if only one db or no need to compare the database size, 
#then comment the removing db phrases for virtuoso!!!

#QUERY:do we need to empty the buffer after each dbms to compare the performance?
#query performance should focus on warm instead of cold
