Oracle is a great database. It is cutting edge and it has a huge team of developers behind it as well as massive funding.
There are not any areas where it lacks anything major that exists in other comparable databases.
The problem with Oracle is both that it is expensive in the first place, but also that all of the extras are chargeable and also expensive!
Oracle is the database to beat in terms performance and features or at least is positioned that way. More importantly, if you are thinking of migrating from Oracle to Postgres to save money, you need to know that your new database has at least the same features at the one that you are moving from.
High availability is one of the most important concepts and features for a database system. For most enterprise level applications, downtime has a direct financial cost and the actual loss of some or all of your data would be catastrophic.
You need to know that the system that you are moving to can protect your data as well as the system that you are on at the moment.
The Oracle database has been the gold standard for enterprise applications for a long time now. It has great performance, solid reliability and most of the features that you could want are available. The big problem is that it is expensive. And I mean REALLY expensive. That’s just for the base product as well. All of the extra features that you might want are chargeable extras which means that wench developing for Oracle, you often have to work without some of the more advanced features because they would cost too much.
