Technical decisions around data persistence are hard, which is why we surveyed 583 IT Professionals on everything from current DBMS and ORM usage to modern database engines’ data structures and access patterns to storing data on a mobile device.
The two most mature commercial DBMS offerings (Oracle and MySQL) are used in production by 51% and 49% of respondents, respectively-significantly ahead of the third-ranked DBMS (SQL Server, at 34%). The top three, and the tight race between the top two, have not changed in years, among our survey respondents as well as on the DBMS ranking aggregator dbengines.com. The nearest NoSQL challenger, MongoDB, remains a distant fourth in production environments.
