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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"IBM Db2 Warehouse is more resilient when dealing with business intelligence applications."

"The solution is stable."

"It can scale effectively as long as resources are available."

"The standout feature of IBM Db2 Warehouse, which is particularly valuable for large enterprises, is its ability to handle big data."

"Provides good security and reliability."

"The analytics engine is not bad at forecasting predictions."

"It can be mounted on the cloud, which is a huge plus. If the client, for example, starts small with on-premise deployment and then it rapidly needs to grow, we can transfer this to the cloud easily."

"IBM Db2 Warehouse is more resilient when dealing with business intelligence applications."

More IBM Db2 Warehouse pros

"The most valuable feature would be the fact that it has been running for awhile in an appliance format."

"The need for administration involvement is quite limited on the solution."

"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."

"IBM Netezza Performance Server is a cost-effective solution."

"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."

"Speed contributes to large capacity."

"The data governance prospect... from what I've seen, that is a really powerful tool as well, to help with data lineage and keeping track of that."

More IBM Netezza Performance Server pros

Cons

"The primary challenges customers face with IBM Db2 Warehouse are related to its complexity in usage. It requires highly skilled professionals who understand Db2, and both training and support are challenging to obtain."

"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."

"IBM Db2 Warehouse needs to improve its interface."

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

"It takes a long time to have a new version or release, similar to Oracle."

"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."

More IBM Db2 Warehouse cons

"Disaster recovery support. Because it was an appliance, and if you wanted to support disaster recovery, you needed to buy two."

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

"Oracle Exadata's security features, like TDE encryption, are missing in IBM Netezza Performance Server."

"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."

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

"Our main problem with it is concurrency. When there are too many users running Netezza at the same time, this is when we have the most complaints."

"In-DB processing with SAS Analytics, since this is supposed to be an analytics server so the expectation is there."

"Concurrency limit needs to be increased somewhat."

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."

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

"Expensive to maintain compared to other solutions."

"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."

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

"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."

"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."
