![]() ![]() PostgreSQL is capable of accommodating any volume of data. Not only is it much lighter than Oracle, it doesn’t require users to spend more money to expand infrastructure. While both solutions are quite capable in this category, PostgreSQL may have a slight advantage due to its open-source characteristics. ![]() Scalability – too close to call definitively.PostgreSQL supports full serializability via serializable snapshot isolation (SSI). Requesting a Read Uncommitted transaction isolation level provides read committed instead. It offers three levels of transaction isolation: Read Committed, Repeatable Read and Serializable. That doesn’t mean, however, that PostgreSQL has poor functionality. Its experience with various industries also gives it the upper hand. ![]() Oracle is secure and ensures that user data is not tampered with through prompt updates. However, it should be noted that many of Oracle’s security features come at an added cost. It not only provides more transactions per second than PostgreSQL, but also arguably provides higher levels of security. Oracle Database has decades of experience and high levels of development expertise. Large organizations that choose to implement PostgreSQL can also opt for paid professional support, where services tend to be cheaper than their Oracle counterpart. This is not the case with Oracle, where support costs money. Even answers to questions that arise during installation or upgrades are easy to find with minimal delays. PostgreSQL has an extremely active community where patches, tweaks, updates and more can be found very easily. This factor alone can prove to be crucial when it comes to small and medium-sized organizations.Īnother win for the open-source solution. PostgreSQL easily clinches this comparison since acquisition, installation and support is completely free of charge. Oracle is a commercial solution that has steep pricing options, with additional payments required for extra features. Both methodologies are very popular today, but PostgreSQL has gained market share recently and is trending upwards because (some have claimed) it has features more suited to today’s dynamic development requirements.
