One of the features that stands out to me is the Real Application Cluster. This gives us the ability to have active-active clustering functionality. We can scale horizontally to multiple database servers and instances, which gives us both High Availability and load balancing, great features both.
There's also the new In-Memory feature that allows us to do a lot of OLAP transactions.
Improvements to My Organization
As with any organization, before we embark on anything, we have to look at the ROI as well as the ability of a particular tool. Database is rock solid, which, of course, affects our ability to do work and provide customer service. We're a mutual fund company, so stability is really key in providing satisfactory customer service. Oracle Database really gives us this key factor from an IT perspective.
Room for Improvement
We'd like to see a few more security improvements. Security right now is a very, very big issue. Oracle is doing a very good job with security enhancements with each now releases, the latest of which, I think, is 12c release 2. But I'd really like for it to have a lot more security enhancements that are added to Database, rather than pushing the enhancements into some of their other tools that you have to buy in order to be able to take advantage of those enhancements and functionalities. Like I said, security really is key for us as we do a lot of encryption, so it would be best if the additional security features and enhancements were part of Database rather than part of some other product we'd have to buy.
Deploying it was no problem. We had no issues with it at all.
Stability is not an issue at all. Oracle is a database company and Database, as their flagship RDBMS, is the product at the highest level of maturity.
It's scaled to our needs.
Customer Service and Technical Support
We have premier support from Oracle, so we have a very good relationship with technical support.
It's the most mature Oracle product, so setting up the RDBMS was straightforward.
Despite the fact that it's the most expensive of the RDBMS solution available, there's a reason why Oracle Database has the largest market share. It's the best there is. If there's another RDBMS vendor that provides some functionality that Oracle doesn't, then you'd really have to evaluate what your true ROI will be. From my perspective, though, Database is worth it.
