Featured Reviews

Josef Kraus - PeerSpot reviewer
Useful for ETL process and has good documentation
The tool's most beneficial feature for our data management tasks has been the ETL process. Additionally, we utilized Windows and Linux. IBM Db2 Warehouse's scalability has significantly impacted our data storage capabilities. We needed to order new disks for storage every week within this hosting environment. Additionally, we implemented protection measures for production use. The tools are readily available, and if you're willing to invest in them, you can access a good data warehouse without any issues.
Arun Kumarasamy - PeerSpot reviewer
A highly scalable solution that has the best technology and is designed for huge database workloads
It's an entire hardware box where the software and the hardware combination can fasten our queries for the database. The tool has an intelligent cell server where the data is processed at the storage layer rather than the server layer. The tool supports our big data analytics and data warehousing needs. It is the best solution for OLTP and data warehousing. Oracle has the best database technology in the world. Exadata is the best hardware machine designed for huge database workloads along with OLTP.

Quotes from Members

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

Pros

"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."
"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."
"The solution is stable."
"Provides good security and reliability."
"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."
"The analytics engine is not bad at forecasting predictions."
"Some of the best features are stored procedures, parallelism, and different indexing strategies."
"The offloading of data to the SIM is a valuable feature."
"Oracle Exadata is stable."
"The most valuable feature is storage offloading."
"Oracle has reliable solutions and this one is no different."
"Exadata with the In-Memory option is several levels about SAP HANA."
"The most valuable feature of Oracle Exadata is the smart scan. We have large TB sessions of approximately 100 per second for each of our three instances. The smart scan allows us the obtain data in time in the enterprise manager."
"It is a highly relevant option with extreme performance."
"Exadata's best features are its performance during redo logging and the elasticity of the database handling."
 

Cons

"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."
"There should be more material available for training and training should be free."
"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 challenge anyone could have with Db2 Warehouse is their references or online resources and documentation. They are very, very, very limited on the web."
"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."
"Responding to support tickets takes a lot of time. It can range from two to four days, even for critical issues."
"A room for improvement in Oracle Exadata is that it's not very easy to use in a microservices environment. It's not easy to split databases, and if this was easier to do in Oracle Exadata, it would make the solution better. What I'd like to see in the next release of Oracle Exadata is for it to become more modular, so you can use it in a context where the data layer is spread between many independent services."
"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."
"Since the product is an appliance, it is very costly."
"The setup is a little bit complex. We would like to see the installation part get easier."
"I have found Oracle Exadata to be scalable. However, you have to purchase more hardware, such as memory."
"Oracle Exadata could improve the platform performance tuning should be easier, automated, and user-friendly."
"The cost of the solution is high and can be improved."
"In a future release, I would like to see some upgrade analysis advisors to help with a clear roadmap on steps that need to be taken and some of the automated processes."
 

Pricing and Cost Advice

"In a traditional on-prem database, in a data warehouse, the solution is probably on the expensive side."
"The pricing of Oracle Exadata is too high."
"Exadata is an expensive tool, but, considering the ROI, it's worth going for the solution."
"There is an annual license to use this solution. The solution is expensive."
"The price is very high."
"The cost of the product could be improved."
"I give the pricing of the solution a five out of ten."
"The price of the solution could improve, it is expensive."
"I think it's free."
