equivalent non-opensource database of postgresql -
actually have been asked not use open source databsae. so, have use proprietary database. doubt best equivalent proprietary database of postgresql , should cost effective.
please give suggestion
the decision maker here has weird ideas - not open source, don't care use long don't have source code? that's nuts.
maybe don't understand open source licenses , confusing gplv3 the simple bsd/mit-like license postgresql under? might have images of "open source" meaning kind of terrible viral license takes patents , forces them open source code touches (which isn't true of gplv3, btw). try sending them the wikipedia article, freebsd's article on license, , of openbsd. should read the osi faq. if they're still determined waste money after reading , doing little basic research, there's no saving them.
in case, take postgresql source code, rename "proprietarydb", whack on restrictive all-rights-reserved license, , sell them $5000/server perpetual license. postgresql under bsd-like license , you're permitted long don't delete copyrights sources or claim wrote it. i'll gladly little $4000/server, real bargain ;-)
more seriously, there quite few proprietary postgresql forks already, notably:
- paraccel
- greenplum database
- enterprisedb postgres plus advanced server
... , amazon sell paraccel based db service, redshift, too.
amazon rds postgresql arguably closed source fork too, though tracks mainline postgresql closely , there doesn't seem real difference if any.
