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

"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."

"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 solution is stable."

"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."

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

"Provides good security and reliability."

More IBM Db2 Warehouse pros

"I like this solution's ease of design and the fact that its performance is quite good. It is stable as well."

"It's the same as your visual database. I like the fast load feature for data, the BTQ solution is very good, and storage procedures are very fast."

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

"The data processing, clustering, and distributed computing are impressive."

"The ability to handle machine data parallel processing is the most valuable feature of Teradata."

"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."

"It is quick, secure, and has less hassles because we don't have to involve our networking team, infrastructure, etc. It is very easy to deploy and make market ready."

"We did performance testing. We had a set of real life MicroStrategy reports. Our conditions were: Not allowed to redesign data model, not allowed to rewrite the queries, all queries should be generated by MicroStrategy, no aggregates. Teradata appeared to be way faster than a similarly configured (in terms of hardware) Oracle server."

More Teradata 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."

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

"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 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."

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

"Lacks sufficient documentation and particularly in Spanish."

More IBM Db2 Warehouse cons

"The scalability could be better. The on-premises solution is always more complicated to scale."

"The initial setup was complex as we had to rewrite a lot of the code."

"The only issue our company has with Teradata IntelliFlex is that it is not cost-effective because of the way the product has been designed."

"Teradata's pricing is quite high compared to Redshift, Synapse, or GCP alternatives."

"There is a need to improve performance in high transaction processes, as well as the reporting system."

"The cloud is the new challenge and the new opportunity."

"Query language and its functionality are rather limited, compared to Oracle or even SQL Server. However, it is possible to perform any kind of logic in it (though some workarounds may be required)."

"Teradata's UI could be more user-friendly."

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."

"It is still a very expensive solution. While I very much like the pure technological supremacy of the software itself, I believe Teradata as a company needs to become more affordable. They are already losing the market to more flexible or cheaper competitors."

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

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

"Teradata is expensive, so it's typically marketed to big customers. However, there have been some changes, and Teradata is now offering more flexible pricing models and equipment leasing. They've added pay-as-you-go and cloud models, so it's changing, but Teradata is generally known as an expensive high-end product."

"The solution requires a license."

"We had a lot of parties involved when purchasing from the AWS Marketplace. They are very flexible and aggressive in trying to close the deal. They are good at what they have to offer and listening to the customer. It's a two-way street."

"The cost is substantial, totaling around $1.2 million, solely dedicated to upgrading the hardware."

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