As interest in open-source databases builds, data management veterans IBM and Microsoft argue that alternative open-source databases such as MySQL lack the strength and functionality for enterprise deployment.Although Sun has not positioned MySQL as an alternative to larger transactional databases, executives speaking at the launch of the LX50 server in August said MySQL offers enough functionality to be a viable alternative in many cases.Open-source databases "dont support as many users, they dont support as much data, and you dont have as many connectivity options," said Jeff Jones, director of strategy for data management solutions at IBM. "They lack some key functionality and lack the scalability and performance, which keeps them out of the enterprise," Jones said.
