My story emphasized that both Solid and mySQL originated in Finland, but your comments and further research showed that the real question is whether Solid's contribution, called the Solid DB Storage Engine for MySQL, really makes it a valid alternative for enterprise database development.
Small companies face a Hobson's Choice as they grow. They may start with mySQL, a solid, simple database, but they wonder whether it will scale as they grow. Given the penchant of Web companies to grow exponentially if they turn out to be winners, this is a question that is occuring earlier-and-earlier in these companies' lives.
There are other options out there, open source databases like PostgreSQL. You no longer have to pay Oracle's monopoly rent.
And if you believe that, then this was the biggest story of 2006.
