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.

Has consistently delivered high performance and aligned security while evolving with AI-driven improvements

When discussing Oracle Exadata, the main thing is the specialized database appliance, the flash cache, and the engineered machine on the database for the database itself. Overall, all the features are useful and meaningful for any database like Oracle to run the Oracle database. Regarding Smart Scan technology, it is for better performance. If a customer cannot tune their applications, this will help them to run the database and run the application without any tuning itself. Oracle Exadata's advanced compression techniques have affected my customer's data storage efficiency positively, with the feature being great, but as of now, our customer is not using that. I find its security measures align with my customer's organization, as security is aligned as per the customer's requirement. It has helped optimize performance and cost.

Quotes from Members

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

Pros

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

"It's easy and practical to use."

"The initial setup was really easy; it's Docker compliant, you just pull the image from the IBM repository and that's it, and the deployment must have taken less than an hour, making it really fast to have it completely working."

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

"Provides good security and reliability."

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

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

"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

"The key capability of Exadata, which is not found in any other solution or appliance, is its enhancement specifically for databases."

"The product is flexible."

"Oracle Exadata is the most stable system I have used."

"The main benefit is that everything is powered by Oracle; the whole box, hardware, software, and storage, so we have the flexibility of going to one vendor directly instead of going to multiple vendors if we have any issues."

"On-premises Exadata is just as stable as the cloud version. It's a very stable platform."

"No one else could provide a solution with this performance, for us."

"Complete management occurs from one single address instead of different servers."

"Exadata's best features are its performance during redo logging and the elasticity of the database handling."

More Oracle Exadata pros

Cons

"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 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."

"I previously used DataStage, which I think is better than InfoSphere Warehouse."

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

"On a scale of one to ten, I would rate the technical support as a five. It is fairly bad."

"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."

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

More IBM Db2 Warehouse cons

"I don't think it's so scalable because Exadata is a box."

"Initial set-up was a bit complex, but everything was resolved pretty quickly."

"We have had issues with system restoration."

"One small area for improvement in Oracle Exadata is integration, particularly at the consolidated application level."

"The ASR system with the jump gate was more problematic than the Exadata setup."

"There is one aspect to Exadata that I dislike, and that's the inconsistency with other databases. When you try to get Exadata to function with another type of database like SQL, or others, there should be reliable and consistent operation. When this is improved on, we should start to see more applications growing the market."

"One improvement would be the limitation on the storage."

"The improvement could be made on the hardware level as the habit in the industry is to go better and faster and larger with every iteration."

More Oracle Exadata cons

Pricing and Cost Advice

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

"The majority of our customers are in government or big enterprises, and the projects that we sell come out to several million USD. With this amount of money on the table, it's always better to have an experienced team of consultants, who know Exadata very well, handle the implementation."

"The price is very high."

"Oracle is always costly but it's fine."

"In the sizing phase, you can also decide whether to license all cores, or reduce the number cores using capacity-on-demand features of Exadata, as well. This has a direct impact on licensing."

"The Initial investment price could use improvement"

"The price of the solution has been expensive to implement."

"It is quite expensive."

"I'm giving Oracle Exadata five out of ten in terms of pricing. Its price could be lower."
