Executive SummaryUpdated on Sep 30, 2025

Teradata and IBM Db2 Warehouse compete in the data warehousing category, with both offering high-performance solutions. Teradata often has the upper hand due to its parallel processing capabilities and broader toolset, leading to a more superior user experience.

Features: Teradata is praised for massive parallel processing, efficient resource allocation, and quick query processing across large datasets. Its Viewpoint tool provides valuable insights for system tuning. IBM Db2 Warehouse excels in handling big data and offers strong analytics capabilities, especially for business intelligence applications. It is recognized for its scalability and data retrieval speed.

Room for Improvement: Teradata could enhance cloud integration support and offer more flexible pricing. It also faces challenges with complexity and transaction processing improvements. IBM Db2 Warehouse needs better online resources and documentation to aid self-service troubleshooting. Faster technical support response times and better user guidance are also necessary enhancements.

Ease of Deployment and Customer Service: Teradata supports versatile deployment across on-premises, public, private, and hybrid clouds, ensuring flexibility. It generally enjoys robust support but could benefit from improved response times. IBM Db2 Warehouse focuses more on on-premises and private cloud setups and, while generally well-regarded, also needs improvements in response times.

Pricing and ROI: Teradata is considered a premium choice with high cost, delivering significant ROI, though its pricing may limit smaller businesses. In contrast, IBM Db2 Warehouse has pricing comparable to Oracle, perceived as high but valuable by clients willing to invest. Both solutions require understanding total costs for optimal ROI.

Senior Technical Manager- IBM Enterprise Systems at SYSTEMS INTEGRATED LTD (SYMPHONY)

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 improved data quality, optimized reporting processes, and enabled predictive insights across business units

The limitation we encountered was related to speed, prompting us to increase our AWS cloud thresholds and benchmarks on the servers, adding more throughput. We have been testing that, but speed remains one of our key issues. The integration has been awesome because of the platforms and their usage, and usability is great. The most challenging aspect is finding Teradata resources, so we are focusing on internal training and looking for more Teradata experts. If Teradata could provide a list of certified experts, that would be fantastic. I rated Teradata a nine because the main area for improvement is the bandwidth of resources that could assist us in applying to our projects, specifically more certified and expert resources. The market share of Teradata professionals is limited, creating an issue for us.

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."

"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."

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

"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 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 scale effectively as long as resources are available."

"Provides good security and reliability."

More IBM Db2 Warehouse pros

"The most valuable feature of Teradata is security. It runs on Unix and Linux platforms which provide better security."

"The cloud is ten times better than physical hardware; it is more cost-effective and the upgrade process is ten times easier."

"Teradata effectively uses parallelism to the granular level, performing better than other databases."

"Intelliflex is very scalable. In fact, scalability has improved 100 times by Intelliflex, in my personal opinion."

"Teradata can be deployed on-premise, on the cloud, or in a virtual machine, which means customers can move without having to create their architecture all over again."

"Teradata has positively impacted our organization by allowing our team to reduce from 27 people down to eight, consolidating our headcount, and helping the enterprise achieve a higher rate of internal return on financials."

"I found all parts --loading, transformation, processing & querying work in parallel, and end-to-end-- to be valuable."

"The feature that we find most valuable is its ability to perform Massive Parallel Processing."

More Teradata pros

Cons

"Lacks sufficient documentation and particularly in Spanish."

"IBM Db2 Warehouse needs to improve its interface."

"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."

"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 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."

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

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

More IBM Db2 Warehouse cons

"The setup is not straightforward."

"The solution needs improvement in its stability, support and pricing."

"Teradata is a bit late for the cloud."

"Limited interest and success in some areas make us hesitate about upgrading."

"Teradata needs to pay attention to the cloud-based solution to make sure it runs smoothly."

"If I want to implement an upgrade, I'd like to see how it will be different. Ideally, Data Lab should help me test production items and also do future things. Future releases should be downloadable and testable in Data Lab."

"The tool's flexibility and capacity for expansion are areas of concern where improvements are required."

"GUI of administrative tools is really outdated."

More Teradata cons

Pricing and Cost Advice

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

"Teradata pricing is fine, and it's competitive with all the legacy models. On a scale of one to five, with one being the worst and five being the best, I'm giving Teradata a three, because it can be a little expensive, when compared to other solutions."

"Teradata is expensive but gives value for money, especially if you don't want to move your data to the cloud."

"The product cost is high for what the client gets. There may be more cost-effective solutions for small and medium-sized organizations."

"When looking into implementing this product, pricing is the main issue followed by technical expertise."

"We are looking for a more flexible cost model for the next version that we use, whether it be cloud or on-premise."

"The solution requires a license."

"The price of Teradata could be less expensive."

"The price of Teradata is on the higher side, and I think that it where they lose out on some of their business."
