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.

Automated provisioning simplifies deployment and integration

The Oracle Database Appliance is customizable and has excellent features.I don't have any problems with Oracle Database Appliance because this product is very automated, with scheduler and automatic processes throughout. You can make small inferences and changes for creating all the specific modifications. The automated provisioning feature helps speed up the database deployment process because you can use one command or option to resize all the disks or increase memory, depending on the occasion. The Oracle Database Appliance has integration in OCI Cloud. The same services simplify all the manager work regarding backups, configuration, resizing disks, and other services. Deploying the Oracle Database Appliance both on-premises and in the cloud offers the same simplification. You simply input your database name and specify memory quantity, CPU quantity, and database size. The process is identical for both on-premises and cloud deployments. The flexibility of Oracle Database Appliance has helped grow business needs for many customers. Using the Oracle Database Appliance has positively impacted my organization because I can deliver it much more comfortably. Creating a database involves many processes, but with this solution, you just input the name and configure the network and other parameters. It is very similar to RDS in AWS services, where you specify the name, choose the engine, indicate parameter groups, VPC, subnet groups, and proceed. Both Oracle Database Appliance and RDS have greatly simplified the work.

Quotes from Members

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

Pros

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

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

"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 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."

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

"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

"I give it a nine out of 10 because it gives the customer easy access to a complete database solution within 30 minutes."

"The product is good value for money. It is a secure solution."

"The performance of the system is the solution's most valuable aspect. In combination with the database, it gives perfect results. It's a better system than using other kinds of integrated systems. In general, the ODA control is much simpler to use and offers up the best performance."

"The most valuable feature is the performance."

"The database is solid."

"The most valuable feature of the solution is the ability to combine all the data without the need for additional devices."

"Oracle Database Appliance provides high stability."

"The most valuable feature of Oracle Database Appliance is the ease of management."

More Oracle Database Appliance pros

Cons

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

"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."

"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 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."

"Lacks sufficient documentation and particularly in Spanish."

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

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

"The areas of the solution that is needing the most improvement are separating compute from storage, elasticity, which means scaling up and then retracting."

More IBM Db2 Warehouse cons

"The product's pricing is too high. We plan to migrate to another database in three to four years."

"I would rate the scalability a seven out of ten. It has some problems. Databases are huge. This leads to needing more and more RAM and capacity resources, making it hard to scale. Because of this, we use Exadata. That's definitely a point for improvement."

"If we were able to use Oracle Database to create mobile apps, that would be great. I don't know multiple languages, like Java, etc. I need to learn a separate language, right now in order to do this."

"Oracle could improve its capacity for built-in visualization."

"There is room for improvement in better integration with third-party tools, such as Power BI or Redshift."

"For the cloud version, there could be better storage options or more storage for lower prices."

"The main thing would be to make ODA more affordable, to make it a more economical machine. Also, I would like to see virtualization, so you could implement all of your functions on one machine. Finally, improvement in the speed and performance would be good."

"Technical support is not so great. It could be much better. The maintenance, for an enterprise system, isn't so great. It's also extremely expensive."

More Oracle Database Appliance cons

Pricing and Cost Advice

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

"In regards to licensing, it is cheaper to maintain for Oracle applications, and it's an all-in-one solution."

"Oracle’s pricing is ridiculously high."

"Oracle Database Appliance is a very expensive solution. If you have opted for the on-premises licenses from Oracle, then you have to pay yearly. If you have opted for the cloud subscriptions offered by Oracle, then you can pay either monthly or yearly."

"The price of the solution should be less expensive. However, they will increase the price more."

"The price should be lower."

"I don’t know ODA and alternative system prices. But Oracle the database license is quite expensive and a lot of my customers plan to migrate to open source databases like PostgreSQL."

"Oracle Database Application's support and maintenance are included in the contract."

"Get benefit from the capacity-on-demand features. License your cores according to your licenses."
