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.

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

"Some of the best features are stored procedures, parallelism, and different indexing strategies."

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

"If you have good people designing how the data is stored, it's a marvelous tool."

"The most valuable features of IBM Db2 Warehouse include its availability, easy integration, ability to deal with a large size of data, excellent performance with no delays, powerful security mechanisms, and effective support."

"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."

More IBM Db2 Warehouse pros

"Those reports were improved from a couple of hours to minutes."

"The performance is most important to me, and it helps our ability to make business decisions quickly."

"Speed contributes to large capacity."

"It can run heavy CPU queries really fast, and this is valuable."

"The performance is most important to me, and it helps our ability to make business decisions quickly."

"We are able to execute very complex queries. Over 90 percent of our query executions are one second or less. We do millions of queries everyday."

Cons

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

"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."

"IBM Db2 Warehouse needs to improve its interface."

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

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

"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."

More IBM Db2 Warehouse cons

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

"We are not able to scale. The only way to scale is to get another appliance, but we have a customers who would need us to hydrate the data between the two appliances, and Netezza does not do that."

"Concurrency was an issue. If you run small queries it runs well, and the performance is good, however, when you run multiple long queries or multiple joins, it has some concurrency issues."

"We tried to install a newer version of NZA not supported by the version of Netezza we had and it did not work."

"Correlated queries are not supported."

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

"The only issue is that it's not expandable."

"The most valuable features of this solution are robustness and support."

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."

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

"Expensive to maintain compared to other solutions."

"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."

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