Forrester Research released a report that is optimistic about the future of open source databases in the enterprise. Improvements in security, availability, integration, automation and unstructured data management will make these low-cost platforms even more attractive for enterprise application.
Forrester analyst Noel Yuhanna predicts 30 percent of enterprises will use open source databases in production by 2008.
Another well known example is Apache, which supports 67 percent of web sites on the Internet.
