PostgreSQL

Open source multi-platform SQL database with fairly strong transaction control that is more scalable than most other open source equivalents. It has support for unlimited database size, although in practice that may require multiple computers to host it, but distributed databases may be held of systems with different operating systems. It has native programming interfaces for C/C++, Java, Perl, Python, Ruby, Tcl and ODBC.
