Oracle won hard fight to own MySQL but only because many misunderstand how the two will co-exist.

Not everyone believes that Oracle’s acquisition of Sun means MySQL’s death, but rather that it will remain alive and well, a group which includes MySQL’s co-founder David Axmark. Their main reason being that Oracle and MySQL are generally in two different markets – MySQL in the web and Oracle in enterprise.

Said David Axmark, one of the developers of MySQL,

"Will they aggressively sell to companies that Oracle can sell to? Never. Will it hurt the current MySQL customers? Probably not," and "There’s no money to be made for them there. Upselling current MySQL customers to Oracle would be tiny money."
