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.

Quotes from Members

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

Pros

"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."

"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."

"The solution is stable."

"Provides good security and reliability."

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

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

"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."

More IBM Db2 Warehouse pros

"Self-patching and runs machine-learning across its logs all the time"

"It provides Transparent Data Encryption (TDE) capabilities by default to address data security issues."

"A very good integration feature that restricts access to unauthorized people."

"The solution integrates well with Power BI."

"It is a stable and scalable solution."

"Oracle Autonomous Data Warehouse is used globally to deliver extreme performance on large Financial data sets."

"The solution is self-securing. All data is encrypted and security updates and patches are applied automatically both periodically and off-cycle."

"It is an extremely scalable solution since you can dynamically change the resources as some other cloud solutions."

Cons

"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."

"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."

"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 challenge anyone could have with Db2 Warehouse is their references or online resources and documentation. They are very, very, very limited on the web."

"IBM Db2 Warehouse needs to improve its interface."

More IBM Db2 Warehouse cons

"The setup is complex."

"An improvement for us would be the inclusion of support for an internal IP, so we could use it directly with the VCN in Oracle Cloud."

"It is very important the integration with other platforms be made to be as easy as it is with an on-premises deployment."

"One of the major problem is creating custom tablespace. The ADB serverless option doesn't support custom tablespace creation, which could cause issues during on-premise database migration that requires specifically named tablespace. There should be an option to create customized tablespace."

"A lot of the tools that were previously there have now been taken away."

"Ease of connectivity could be improved."

"We are not satisfied with the technical support. Their understanding is lacking."

"My main suggestion for Oracle is the configuration and key values that come for JSON files. When we create a table, especially if you see in our RedShift or some other stuff, if I create a table on top of a JSON file with multiple array columns or superset columns, those column values create some difficulty in Oracle."

Pricing and Cost Advice

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

"The solution is expensive."

"The solution's cost is reasonable."

"We pay approximately $70,000 per month. The cost includes maintenance and support."

"ROI is high."

"Oracle Autonomous Data Warehouse's pricing is fair and reasonable compared to the other cloud vendors."

"The cost is perfect with Oracle Universal credit."

"In terms of architecture and pricing structure, I feel it is a little bit costly compared to Azure. It's fine compared to RedShift, but compared to Azure, it's a bit pricey when you calculate for one TB storage plus around five hours of reporting with the frequency of 1TB data. The cost adds up, making Oracle a bit expensive."

"The licensing cost of the product can vary since you can integrate it very easily with other products or other cloud products...You pay as you use it, so it is not yearly or monthly payments to be made toward Oracle."
