Design Oracle Database
Which database is easy to design?
Sql, Mysql, Oracle…
mySQL is open source, has full documentation online, it can be downloaded and installed locally, and nearly every ‘Nix based hosting plan comes with it installed, as does many Windows-based web servers. I use it in both PHP and Perl implementations.
