In this article, we compare Oracle vs. PostgreSQL, outlining the differences in these SQL database costs, features, and ease of use for both developers and database administrators (DBA’s) alike. Oracle requires more complex ongoing administration, as all database configurations must evolve in conjunction with the data schemas and custom code.
