Advanced features enhance business intelligence, but complex management calls for improved user guidance

While my experience with IBM Db2 Warehouse is somewhat limited, when compared to other databases such as Oracle, there are areas for improvement. They need to enhance the database to make it more user-friendly and easier to master. They should implement a more comprehensive graphical user interface with additional features. For instance, when users encounter problems, the system should provide better guidelines and troubleshooting directions, except for hardware-related issues. They need to implement tools that would help users perform basic troubleshooting rather than solely relying on support. Other databases have features where users can investigate specific issues using error codes. From my experience, many minor issues could be resolved before escalating to support.

Parallel data processing streamlines operations while cost and cloud integration challenge adoption

The cost of the solution is on the more expensive side, which is a concern for me. Additionally, its promotion and interaction with cloud applications are limited. The cloud version is only available in AWS, and in the Middle East, it is not well-developed in the Azure environment. For the cost to be reduced, it should match competitors. Many features need to be incorporated on the cloud.

"I think it scales really well and as long as you take enough time to learn a little bit about it, it works really well."

More IBM Db2 Warehouse pros

"Speed contributes to large capacity."

"Parallel data processing is a significant feature for me."

"The underlying hardware that IBM provides with this appliance is made for a specific purpose, to serve performance on a large amount of data, and to do analytics as well. It is faster, when you compare it to any other product."

"The benefit is really because of the additional speed that we have and, truth be told, the more updated ETL processes and the revamped scheduler in general."

"Distribution concurrency control."

"It is a back end for our SSIS, MicroStrategy,, Tableau. All of these are connecting to get the data. To do so we are also using our analytics which is built on the data."

Cons

"In terms of improvement, IBM Db2 Warehouse should be more scalable."

"There were some initial challenges with IBM Db2 Warehouse about eight months ago when I worked in this environment. When I coordinated with IBM support, they mentioned that the memory was insufficient for our needs. Our business environment required significantly more memory than the previous cluster could provide. Consequently, we have worked closely with on-site IBM technical personnel to address this issue."

"Lacks sufficient documentation and particularly in Spanish."

"The areas of the solution that is needing the most improvement are separating compute from storage, elasticity, which means scaling up and then retracting."

"IBM Db2 Warehouse needs to improve its interface."

"There should be more material available for training and training should be free."

"Responding to support tickets takes a lot of time. It can range from two to four days, even for critical issues."

"The biggest problems we have is when the backup solution is failing or slow and we run out of log space, which has happened probably a couple of times in the last four years."

More IBM Db2 Warehouse cons

"The hardware has a risk of failure. They need to improve this."

"The product cost is high compared to others in the market, and this cost has become unbearable for me."

"LIke Teradata, we can’t add a node/SPU to the existing appliance."

"The Analytics feature should be simplified."

"This product is being discontinued from IBM, and I would like to have some kind of upgrade available."

"I'm not sure of IBM's roadmap currently, as the solution is coming up on its end of life."

"Administration of this product is too tough. It's very complex because of the tools which it's missing."

"In terms of features that I would like to see, one is the ability to actually scale out an architecture. Right now, if you buy one, it's fixed. There is no scale-up availability at all."

More IBM Netezza Performance Server cons

Pricing and Cost Advice

"In a traditional on-prem database, in a data warehouse, the solution is probably on the expensive side."

"For me, mainly, it reduces my costs. It's not only the appliance cost. There are also support costs and a maintenance costs. It does reduce the costs very drastically."

"Netezza is a costly solution. It does serve a specific purpose but it's costlier than what's available in the market, if you go to the cloud."

"Expensive to maintain compared to other solutions."

"The pricing is very expensive. It has a lot CPUs with a lot of components in it. It also has built-in redundancy for resiliency reasons."

"The solution has a yearly licensing fee, and users have to pay extra for support."

"The annual licensing fees are twenty-two percent of the product cost."
