The 451 Group's research also found that enterprises remain concerned about issues such as support, security and functionality, and were largely using open-source databases for non-mission critical applications. Adoption was driven largely by a desire to avoid paying for additional database licenses from proprietary vendors for new projects in specific application areas, such as development and testing environments.
In addition, migrating from a proprietary database to an open-source database remains a costly process for many enterprises.
Still, Matt Aslett, an analyst with the 451 Group, pointed out research from ChangeWave that shows 26 percent of U.S. software purchasers are planning to decrease their spending on database management systems in the next 90 days.
"That suggests a potential upturn for open source, although given the cost and complexity of database migration projects, it is more likely that enterprises will postpone spending on new projects and begin to look at potential alternatives, rather than shift their attention wholesale to open source," he said.
In the end, economic conditions are not enough to cause a significant swing in adoption, noted database industry analyst Peter O'Kelly. There are also factors such as developer training and salary expectations of experienced developers to consider.
"I imagine some organizations will revisit open-source alternatives as a means of potentially cutting costs, but I don't think it'll radically change the current picture," he said.
