Oracle will be allowed to take over Sun Microsystems, the European Commission said today.

Neelie Kroes, the antitrust commissioner gave complete clearance to the deal - Oracle bought Sun for $7.4 billion.

She said she is satisfied that competition will be preserved by the takeover. But that's come after months of investigation into the deal. Part of the worry was that the open source database MySQL would turn into a shadow of its former self, seeing that Oracle is primarily a database company.

American authorities had already cleared the deal, and late last year Oracle helped the EU process by saying that it would continue to develop MySQL and to keep it free.

That's obviously allayed a lot of Ms Kroes' fears.
