"Db2 Database has given us good results since we have started to use it. We predominantly use IBM hardware, and this is one of the reasons why we started to use Db2 Database. Db2 Database has a very good HADR capability. High availability resilience is also good in this solution. It also has pureScale, which allows you to upgrade one node to get very good and high-level resilience. If you are using a database on five nodes, you can take one node down, upgrade that, and let that node up. You can then bring the second node down, upgrade that, and so on."
"it is very stable and runs smoothly once it is deployed and it is almost maintenance-free."
"We are dealing with millions of transactions a month and the performance is very good."
"Its robustness, scalability, availability, and performance are valuable. All these are the major attributes of a relational database for supporting a very high-volume business, and Db2 is very good in all those areas and in all those attributes."
"Very good for performance and scalability."
"I like that its true active-active. For example, if there are two instances within a cluster, we can take one of them down and there's no failover or switch over. There's no primary and secondary, it's true active-active. We can take one side down and we can upgrade that with new maintenance or a new version, obviously testing coexistence beforehand, without impacting the business."
"IBM Db2 Database has good performance."
"The most valuable feature is PowerPC support."
"The solution's high availability is its most valuable aspect."
"MariaDB performs well as the backend database for our cloud-based telephony solution."
"The performance is very good."
"A valuable feature is that we can use it for quite a few things, all the things you'd expect from a server—along the lines of Linux's Lightweight Directory."
"From a customer perspective, MariaDB is a good choice for cluster configuration. It's also easy to operate and cheap."
"What I like best about MariaDB is that it is open-source and reliable."
"We use MariaDB for identity provider services. Most of the things that we are doing are deployed in the container mode. All such solutions require a database, and MariaDB is easier to use for these kinds of deployments."
"Installation is straightforward."
"In terms of improvements, IBM Db2 can improve its interface and its functionality. Also, the embedded functions should be much richer than the current ones - the functions which are embedded in the engine itself."
"The GUI interface is not particularly friendly for those who do not have experience with the product."
"It would be helpful to have a hybrid data storage facility that includes NoSQL technologies."
"Their view of it is they're maintaining it, they're continuing to upgrade it, they're continuing to grow it, however, they don't go out and try and sell that as an architectural solution the way they do Linux and Unix."
"The application development requires a Java developer and not every company has these resources."
"They should simplify the management of Db2 as a relational database system. There should be the simplification of management. This is probably one of the most important asks for being successful in the future."
"GUI needs improvement."
"There could be better integration with some cloud solutions."
"MariaDB doesn't handle long or complex SQL queries quite as well as Oracle Database."
"The GUI could be improved a bit. The user interface needs to be improved."
"The product needs more features and more functionality. It's imperative that it supports more platforms, and supports more operating systems."
"MariaDB could be improved by adding more automation."
"When we have had issues with accidental computer shutdown or a power outage, our MariaDB database was corrupted."
"Master-master replication is something that needs to be simplified."
"The stability could always continue to be improved upon."
"I would like to see more compatibility going forward. This would help if there is a need to change databases."
